1 Introduction
1 Introduction
8000 Intelligent Network Manager is an integrated network and service management system for
managing 5500 Digital Cross-Connect Series, 6300 Managed MSPP/Transport Series, 7090 Packet
Transport Platform Series, 7100 Packet Optical Transport Series, 8100 Managed Access System,
8600 Smart Router Series, 8800 Smart Router Series and mTera TM Universal Transport Platform
product families. It offers a Dashboard for performing all necessary functions to create, test and
monitor services provisioned on these product platforms. 8000 Intelligent Network Manager is a
multi-technology platform supporting IP VPN (RFC4364), DWDM optical, Layer 2 VPN, Ethernet,
G.709 OTN, ATM, TDM (PDH, SDH and SONET) and Internet access services provisioned on
top of the supported product families.
8000 Intelligent Network Manager is integrated in its entirety. The tools are integrated together,
they share and utilize the same data and they communicate with each other. The ef ficient data flow
between the tools is gained by the use of the same relational database for all the 8000 Intelligent
Network Manager tools. The database maintains an up-to-date status of the network, elements and
services and this status is shared in a real-time manner to all the tools and users. In a multi-user
environment, this ensures that all those who operate with the network are aware of events or actions
taken by other users in the network. In addition to maintaining the up-to-date status, 8000 Intelligent
Network Manager provides possibility for pre-planning of the network and services in advance.
The supported product families have been readily integrated within 8000 Intelligent Network
Manager and adapters for each product family are offered as an integrated part of the management
system. The network management system is thus ready to command and communicate with the
network elements without any additional modeling or adapter work. All communication to the
network and elements are designed to go through the network management system to ensure that the
consistency throughout the 8000 Intelligent Network Manager is maintained at all times.
With no single point of failure, 8000 Intelligent Network Manager is built to be a reliable and fault
tolerant system that performs well in a diverse environment and under variable circumstances. In
8000 Intelligent Network Manager, the needs of a growing network and operations have been
considered by ensuring the system scalability according to the size of the network and the number
of services and users.
8000 Intelligent Network Manager is designed to take full control over its own domain while keeping
in mind the requirements of operational support systems (OSS) and other domains. Northbound
interfaces can be used to adapt and integrate the system into other service provider’s systems. Via
the northbound interfaces, the OSS has access to the network infrastructure (e.g. elements andnetwork topology), the services (provisioning, monitoring and testing) and other OSS support data.
8000 Intelligent Network Manager brings a consistent yet adaptable way of managing not only the
elements but also the whole network and the services end-to-end within its domain.

1 Introduction
• IP VPNs providing many-to-many connectivity through the network. This connectivity service
is used mainly in the managed IP VPN application and in LTE networks.
• DWDM optical wavelength (channel) management. Optical channels can be used to carry purely
optical signals, SDH circuits and Ethernet services in a single optical channel. The DWDMsystem can be deployed either in a ring or mesh topology.
• Ethernet switching using VPLS VPNs. For many-to-many Ethernet connectivity, VPLS VPNs
can be used and configured on 8600 and 8800 network elements. The VPLS service specified
in RFC 4762 (Virtual Private LAN Service Using Label Distribution Protocol Signaling) is sup-
ported, which allows creating private Ethernet switching networks built of virtual switch in-
stances (VSI) interconnected with MPLS pseudowires.
• Ethernet switching using VLAN VPNs. For many-to-many Ethernet connectivity, VLAN VPNs
can be used and configured on 6300, 7090, 7100, 8100 and 8800 network elements. In the 8800
network element the VLAN VPN service is terminated to a VPLS/PW VPN service. Ethernet
switching is done in Ethernet switching capable units and the Ethernet traf fic transported over
shared TDM pipes in the 6300 and 8100 based network and optical channels in the 7090 and 7100
based networks. Due to the statistical nature of the Ethernet traf fic, the operator may choose tooversubscribe the network.
• Ethernet tunneling over MPLS using Ethernet PWs providing point-to-point connectivity through
the network. The PWE3 tunneling method is used. This point-to-point service is also sometimes
referred to as virtual private wire service (VPWS). Ethernet pseudowires are used both in the
managed Ethernet services application and broadband service aggregation application.
• G.709 OTN services. As the DWDM circuits, the OTN circuits can be used to carry different
types of signals across a network. Unlike the DWDM circuits, rerouting OTN circuits does not
require any re-configuration of the underlying hardware (e.g. cabling) leading to lower overall
costs in the network operation.
• ATM tunneling over MPLS using ATM pseudowires. ATM pseudowires provide point-to-point
connectivity through the network for tunneling ATM circuits over an MPLS or IP infrastructure.The PWE3 (pseudowire emulation edge-to-edge) tunneling method is used to tunnel the ATM
traf fic. This point-to-point service is sometimes also referred to as a virtual private wire service
(VPWS). This is the main connectivity service used in the mobile transport application for 3G
traf fic in R99 and R4 networks for transporting traf fic between the base stations (nodes B) and
the radio network controllers (RNCs). ATM tunneling can also be used in the broadband service
aggregation application for tunneling traf fic from ATM DSLAMs over an MPLS infrastructure.
• TDM tunneling over MPLS using TDM pseudowires (PWs). TDM pseudowires provide point-
to-point connectivity through the network for tunneling TDM bit streams over an MPLS infra-
structure. The PWE3 tunneling method is used. TDM pseudowires can be used to transport 2G
traf fic in mobile radio access networks between the base station and the base station controller
over an MPLS-based access network. TDM pseudowires can also be used to connect mobile
switching centers together over an MPLS backbone. Native nx64 kbps and 1.5/2 Mbps PDH as
well as nx64 kbps and 1.5/2 Mbps PDH bit streams over SDH/SONET are supported.
• PDH and SDH circuit management for the 1/0, 4/1 and 4/4 layers. TDM circuits can be used to
provide leased line services and mobile transport for 2G and 3G RAN networks. TDM circuits
can also be used for LAN interconnection services.
• Frame Relay and HDLC tunneling over MPLS using Frame Relay DLCI and HDLC pseudowires.
Frame Relay/HDLC pseudowires provide point-to-point connectivity through the network for
tunneling Frame Relay PVCs or other HDLC based services over an MPLS infrastructure. The
PWE3 tunneling method is used. Frame Relay/HDLC pseudowires can be used e.g. for trans-
porting GPRS or CDMA2000 1xRTT traf fic.

1 Introduction
• SONET circuit management for the STS-1 and STS-3c layers. SONET high-order circuits can
be used to provide similar services as SDH 4/4 circuits. SONET circuits can be configured and
used on the 5500 and 7100 network elements.
• Basic IP routing for broadband service aggregation applications.
Below, the different connectivity services are described more in detail.
1.2.1 IP VPN
The BGP/MPLS VPN method is the predominant and most scalable way to build MPLS-based
connectivity services. The service is based on RFC4364, which defines the MPLS/BGP-4-based
VPN implementation. Adding a new site to the VPN is easy and automated by the use of BGProuting advertisements. All the traf fic traversing through the VPN can be classified, and traf fic
quality can be handled properly through the network. The VPN allows any traf fic, including voice,
to be transported. IP traf fic from Ethernet frames or ATM/frame relay circuits may be terminated
and routed over the VPN. IP VPN services are used for example in LTE, LTE-Advanced (LTE-A)and 3G mobile backhaul networks.

1.2.2 Dense Wavelength Division Multiplexing
Dense wavelength division multiplexing (DWDM) is an optical technology used for increasing the
capacity and flexibility of the optical infrastructure. In a DWDM system, multiple optical signals
are transmitted over multiple optical wavelengths (channels) on a single optical fi ber. The optical
layer interfaces the digital layer at the optical termination equipment, which can be considered a
part of both the electrical and the optical layer. The optical layer provides multiplexing schemes
and management that are not present on the digital layer of the network. This optical infrastructure
supports e.g. multiple data rates (for example, 622 Mbps, 2.5 Gbps, 10 Gbps) and SDH signal rates.
DWDM units are available for the 6300 and 7100 network elements.

1.2.3 VPLS VPN
VPLS VPNs can be used to provide managed LAN interconnection services. A network of virtual
switch instances (VSI) interconnected with MPLS pseudowires is provisioned per VPLS VPN.
Customer devices are connected to the VSIs, and see the VPLS service as a large distributed
Ethernet switch. Because the VSIs ar e separate to each VPLS VPN, traf fic of different customers is
completely separated from each other.
VPLS VPNs are supported on 8600 and 8800 network elements. Both non-hierarchical and
hierarchical (H-VPLS) services are supported.

1 Introduction
Fig. 18 H-VPLS Service
1.2.4 VLAN VPN
VLAN VPNs can be used to provide managed LAN interconnection services. A VLAN tag is added
to the Ethernet frame to identify the customer at the ingress and the VLAN tag is then removed atthe egress point before forwarding the frame at the other endpoint of the VLAN VPN. The frames
are switched based on the VLAN tag and the Ethernet MAC address. A VLAN VPN may have
several endpoints in contrast to Ethernet pseudowires that only support point-to-point Ethernetconnections. TDM circuits are provisioned between the Ethernet switching points and overbooking
of these transport trunks can be exercised due to the statistical nature of the Ethernet traf fic.
Ethernet switching units are available in the 6300, 7090, 7100 and 8100 network elements. In
addition, a VLAN VPN service can be terminated to a VPLS/PW VPN service in an 8800 network
element. For a protected point-to-point service using the open RVT solution in the 7090 network,
the termination towards the VPLS service in the 8800 network provides dual homing i.e. there aretwo termination endpoints towards the VPLS service.

1.2.5 Ethernet Pseudowire
Ethernet pseudowires are most suitable for those connections that need network layer transparency
also for other than IP protocols. The Ethernet pseudowires are based on the PWE3 architecture. The
Ethernet pseudowires are point-to-point connections much like with Frame Relay virtual circuits or
TDM leased lines. Connections are implemented in the network in such a way that the traf fic is
mapped to MPLS LSPs. If VLANs are used in the network, it is possible to map traf fic from each
VLAN into a separate connection. This provides full VLAN transparency. It is also possible to
terminate Ethernet traf fic from frame relay circuits and transport it over an Ethernet pseudowire.
Service VLANs can be used to aggregate traf fic from multiple Ethernet interfaces to a single
aggregated interface by adding a VLAN tag to the Ethernet frames.
A service class specifying the QoS treatment the traf fic gets in the MPLS network can be defined for
each connection separately.

1.2.6 OTN Circuits
The 7100 Packet Optical Transport Series and mTera Universal Transport Platform supports the
ITU-T Recommendation G.709 optical transport protocol (also known as Optical Transport Network
(OTN)). The OTN is intended to function as an evolutionary step form legacy TDM (SDH/SONET)transport by reducing the inherent complexity of these protocols, and thereby, lowering the overall
capital/operational expenditure associated with such networks.
The G.709 OTN services can be used to transparently transport e.g. SDH/SONET, Ethernet and
optical services across a DWDM network. At the ingress node, the client signal is mapped to
a corresponding Optical Payload Unit (OPU) which in turn is mapped into an Optical Data Unit(ODU). The ODU can then be switched or multiplexed into a higher layer ODU for transportation
across the network. An example is shown in the figure below. Rerouting the ODU is possible at
any point, without any need to re-configure the optical cabling.
The 7100 OTS and mTera UTP as well as 8000 Intelligent Network Manager support the following
ODUks: ODUflex, ODU0, ODU1, ODU2, ODU2e, ODU3 and ODU4.

ODUk Circuit Tandem Connection Monitoring
Customers typically monitor ODUk services end-to-end using the the ODUk PM overhead. The
TCM field is therefore reserved exclusively for customer use and should not be used by any operator
whose network the ODUk service is passing through. The Tandem Connection Monitoring (TCM)
functionality implemented in the network elements allows monitoring the quality of the ODUk
services (i.e. circuits in 8000 Intelligent Network Manager) over a subsection of the network. This
becomes more important if the service passes through many operator networks, as TCM makes it
possible to monitor which subsections of the service are working properly, or having too manyerrors. TCM can also be used for triggering protection switching when a subsection is out of order.

1.2.7 ATM Pseudowire
ATM pseudowires are used in the mobile application for transporting the ATM traf fic over an MPLS
infrastructure. The ATM traf fic is encapsulated in the hub site node in an MPLS packet according
to the PWE3 architecture. The MPLS packet is then tunneled over an MPLS infrastructure which
may be, for instance, an SDH/SONET or Gigabit Ethernet ring. At the RNC site the ATM traf fic isdecapsulated from the MPLS packet and aggregated onto an unchannelized STM-1/OC-3c interface
towards the RNC. Either an ATM VPC or an ATM VCC may be tunneled in an ATM pseudowire.
Three mapping modes are supported for ATM pseudowires: N-to-one cell mode, one-to-one cell
mode and AAL5 SDU mode.
If no MPLS infrastructure is available, pseudowires can also be transported over an IP infrastructure
using IP tunnels. A typical application for MPLS over IP is the transport of Node B traf fic over
DSL lines to the RNC.

1.2.8 TDM Pseudowire
TDM pseudowires are used in the mobile application for transporting TDM traf fic over an MPLS
infrastructure. The TDM pseudowires are based on either the Structure-Agnostic Time Division
Multiplexing (SAToP) or the Structure-aware TDM Circuit Emulation Service over Packet Switched
Network (CESoPSN) specifications. The TDM payload is encapsulated in the ingress node in an
MPLS packet and tunneled over an MPLS infrastructure to the egress node. At the egress node the
TDM traf fic is decapsulated from the MPLS packet and the original TDM bit stream is reconstituted.
In SAToP pseudowires, the bit stream is encapsulated in MPLS without considering any possible
structure that may be imposed on the bit stream. In CESoPSN pseudowires, nx64 kbps channels are
extracted from the bit stream and encapsulated in an MPLS packet. CESoPSN pseudowires allow
traf fic grooming and save bandwidth when only a few of the nx64 kbps channels in an interface
carry user traf fic. SAToP pseudowires minimize delay and are the most bandwidth ef ficient when
the entire E1/T1 port needs to be transported over the MPLS network.

1.2.9 TDM Circuits
TDM circuits are used for providing leased line services and transport in 2G and 3G radio accessnetworks. Both PDH and SDH are widely used in these applications as the operator usually has
an existing PDH/SDH infrastructure that can be utilized for these applications. The 8100 network
elements have been optimized to provide nx64 kbps and E1 PDH circuits as well as connectivity to
SDH networks through mapping of PDH circuits to nxVC-12 and VC-4 SDH containers. The 6300
network elements have been designed for providing cost-ef ficient nxVC-12, nxVC-3 and nxVC-4
SDH connections. The 7100 network elements support n x VC-4 SDH connections.
The SONET technology can be used to deploy similar types of applications using the 5500 and
7100 network elements.
Fig. 26 TDM Circuits
1.2.10 Ethernet First Mile Services
The 8100 product family is complemented with an Ethernet over copper based solution consisting
of 8115 NTUs with the network terminating functionality and 8155 Access Switch nodes with the
aggregation functionality having Ethernet, E1, X.21, V.35 UNI interfaces and SHDSL copper
pairs between them. This platform supports L2 services such as Ethernet Private Line, E-LANand E-tree, as well as TDM SAToP and CES-based circuits where Ethernet packets are carried
over SHDSL/copper.
8000 INM supports adding the nodes to the network, launching the Local Craft Terminal and
managing faults. Services (Ethernet and TDM PW) are provisioned using Local Craft Terminal.

1.2.11 Frame Relay DLCI Pseudowire
Frame Relay DLCI pseudowires are used for transporting Frame Relay permanent virtual circuits
(PVC) over an MPLS network. The Frame Relay DLCI pseudowires are based on the PWE3architecture. The Frame Relay DLCI pseudowires are point-to-point connections, which map
Frame Relay PVCs to MPLS LSPs. Each PVC, identified by a DLCI value, is mapped to a separate
pseudowire (so-called one-to-one mode). In mobile networks, Frame Relay DLCI pseudowires can
be used for transporting GPRS traf fic between Base Station Controller (BSC) and Serving GPRS
Support Node (SGSN).

1.2.12 HDLC Pseudowire
HDLC pseudowires are used for transporting HDLC based protocols, such as Point-to-PointProtocol (PPP), Frame Relay and Cisco HDLC over an MPLS network. The HDLC pseudowires are
based on the PWE3 architecture. The HDLC pseudowires are point-to-point connections, which
map HDLC frames to MPLS LSPs. HDLC pseudowires implement a so-called port mode service,
since all frames from one port are mapped to the same pseudowire (as opposed to e.g. Frame Relay
DLCI pseudowires, which map frames to pseudowires based on the DLCI values). In mobile
networks, HDLC pseudowires can be used for transporting CDMA2000 1xRTT traf fic.

1.2.13 Seamless MPLS
MPLS has been deployed in the core and aggregation networks for several years and provides a
mature and stable basis for large networks. In addition, MPLS is already used in the access networks,
e.g. in the mobile or DSL backhaul. Currently, MPLS as a technology is used on two different layers:
• transport layer and
• service layer (e.g. for MPLS VPNs).

1 Introduction
In both cases the protocols and encapsulation are identical, but the use of MPLS differs especially
with regard to the signaling, control plane, provisioning, scalability and frequency of updates. On
the service layer, only service-specific information is exchanged; every service can potentially
deploy its own architecture and individual protocols. The services are running on top of the
transport layer. However, these deployments are usually isolated, focused on a single use caseand not integrated in an end-to-end manner.
Seamless MPLS provides an architecture which supports a wide variety of different services in a
single MPLS platform fully integrating the access, aggregation and core network. The architecture
can be used for residential services, mobile backhaul as well as business services, and supports fast
reroute, redundancy and load balancing. Seamless MPLS provides the deployment of service
creation points which can virtually be everywhere in the network. This enables flexible service
and service creation for the network and service providers. Services can be created based on the
existing requirements without a need for dedicated service creation areas in fixed locations. With
the flexibility of Seamless MPLS, the services can be created anywhere in the network and easily
moved between different locations.
Many aggregation networks are already deploying MPLS but they are limited to the use of MPLS
per aggregation area. Those MPLS-based aggregation domains are connected to a core network
running MPLS as well. However, most of the services are not limited to an aggregation domain
but running between several aggregation domains crossing the core network. In the past, it was
necessary to provide connectivity between the different domains and the core per service level, and
not based on MPLS (e.g. by deploying native IP routing or Ethernet-based technologies between the
aggregation and core). In most cases service-specific configurations on the border nodes between
the core and aggregation were required.
With Seamless MPLS there are neither technology nor topology boundaries for the services.
Network (or region) boundaries are for scaling and manageability, and do not affect the service layer
since the transport pseudowire carrying packets from the access node to the service node does not
care whether it takes two hops or twenty, neither how many region boundaries it needs to cross. Thenetwork architecture is about network scaling, network resilience and network manageability and
the service architecture is about optimal delivery: service scaling, service resilience (via replicated
service nodes) and service manageability. The two are decoupled: each can be managed separately
and changed independently.
Due to Seamless MPLS, service-specific configurations between the different MPLS islands are
not needed. Seamless MPLS connects all MPLS domains on the MPLS transport layer providing
a single transport layer for all services, independently of the service itself. The Seamless MPLS
architecture therefore decouples the service and transport layer and integrates the access, aggregation
and core into a single platform. One of the main advantages is that problems on the transport layer
only need to be solved once (and the solutions are available to all services). With Seamless MPLS it
is not necessary to use service-specific configurations on intermediate nodes; all services can be
deployed in an end-to-end manner.
An example of the Seamless MPLS deployment for IP VPNs is presented in the figure below.

1.2.14 Internet Access
The 8600 Smart Routers can be used for services in which the customer traf fic flows through the
nodes as basic IP route packets, without MPLS encapsulation or separate routing tables. ResidentialInternet access is a typical service like this. The operator usually provides dynamic IP addresses
for residential users through the DHCP protocol. The 8600 nodes support the DHCP relay
agent functionality, which can be used here. The traf fic from/to different residential customerstypically enters/leaves the 8600 nodes in separate customer-specific VLANs. Usually there is
a shaping/policing function configured in each VLAN to adjust the traf fic rate according to what
the customer has paid for.

2.1 Overall Architecture
2.1.1 Typical Configuration
8000 Intelligent Network Manager is usually installed in a separate Local Area Network in theoperator Network Operating Centre, here referred to as management LAN. An overall configuration
of a typical 8000 Intelligent Network Manager configuration is shown in the figure below.
Fig. 31 8000 Intelligent Network Manager Confi guration
A more detailed description about each of these components will be given later in the following
sections. The management LAN can be physically distributed between different locations. For
security reasons it should, however, be kept separate from the managed Wide Area Network. Only
the Communication Servers should have access to the WAN.

2 8000 Intelligent Network Manager Components and Architecture
2.1.2 Minimum Configuration
Not all of the management system components need to be physically located in separate computers
when the size of the managed network and the number of management system users are small.
Single Server Configuration (SSC) can be used for networks having nodes up to 30 per cent
compared to a single Communication Server (for more information, refer to 8000 Intelligent
Network Manager Third Party Hardware and Software Requirements). SSC combines all of the
management system functions into one computer.
2.1.3 N-tier Architecture
In order to increase system flexibility and scalability, an N-tier architectural style has been applied in
the 8000 Intelligent Network Manager software. N-tier architecture, also often referred to as 3–tier
architecture, essentially means that at least the GUI client, application logic (business logic) anddata storage are separated from each other in a way that allows – but however does not force – them
to be run in separate computers. The advantages of this approach include better scalability (more
servers can be added to be able to handle large amounts of data) and relative easiness to make
changes to one part of the system without affecting the others.
The figure below shows the tiers of the system and their dependencies concerning some of the
network management system tools in a simplified way.

2 8000 Intelligent Network Manager Components and Architecture
2.1.4 Object Server
Object Server (OSR) isolates the 8000 Intelligent Network Manager business logic and GUI toolsfrom the database and network elements. They are offered a set of functions, by which they can
change the database contents, and select data from the database and network elements.
The Data Cacher process speeds up the data selection made by the Object Server. It keeps the
user-defined part of the database contents in the local RAM.
The advantages of the Object Server in multi-user environment include:
• Logical checks that prevent database inconsistency in multi-user environment can be collected in
OSR.
• Object Server collects the latest database changes in a specific database table (osrchan), where
also some additional information on the changes is stored.
• Object Server can inform the network management system tools of the changes in preselected
data, on the condition that all tools that change the corresponding data are also using Object
Server. This feature makes it possible to provide a practically real time view to the network data
to all 8000 Intelligent Network Manager users.
2.1.5 Server Monitoring
8000 Intelligent Network Manager servers can be configured to collect performance statistics of
the server computer and of the individual processes running in that computer. Refer to Server
Monitoring Con fi guration Wizard in the 8000 Intelligent Network Manager Online Help for the
options available. The collected statistics are stored in the database and can be viewed using thePerformance Management application.
2.2 Workstations
Workstations are the computers through which the operators use the 8000 Intelligent Network
Manager through a graphical user interface. Please see the document 8000 Intelligent Network
Manager Third Party Hardware and Software Requirements for detailed requirements concerning
workstation hardware and operating system.
The graphical user interface (GUI) is the interactive tool of network management. It is based
on hierarchical windows for all tools. The windows represent network elements and objectsgraphically. In addition, in some windows network elements and objects are displayed in treeand list view format, which is easy to navigate.
All 8000 Intelligent Network Manager tools are identified by the title bar text. The title bar also
identifies the target object in the network. For example, the Node Manager main window showsthe id and name of the target node in its title bar. The menu bar, where present, displays the sets of
actions available in each tool. The last of these sets is always the Help option.
Normal workstations can be configured to prefer a certain non-unique service instance by name, andto have backup servers if the preferred one cannot be found. In a large installation, the workstations
should be configured so that each group of workstations uses its own set of preferred non-unique
services, and uses the preferred sets of other workstation groups as backup only.

2 8000 Intelligent Network Manager Components and Architecture
The first application the user sees after launching 8000 Intelligent Network Manager in a workstation
is the Dashboard. All available management tools can be launched from there. The Dashboard also
contains small applications, called widgets, which can be used for performing certain operations
(e.g. a search for nodes, trunks and services in the 8000 Intelligent Network Manager database),
monitoring certain aspects of the 8000 Intelligent Network Manager (e.g. faults), or showing the8600 units with the highest CPU load.
Fig. 33 Dashboard
The workstation does not contain any business logic. The business logic runs in a Management
Server (Satellite Service) and all database communication and change notifi
cation handling is donein the management server. Such a Management Server was previously known as a Gateway Server.In 8000 Intelligent Network Manager, the gateway server has been integrated into the management
server architecture as a Satellite service.
All workstations are "thin-client" workstations. Thus, a Management Server running Satellite
Service is required.

2.3 Database Server
Database Server contains a Sybase relational database where all 8000 Intelligent Network Manager tools store their data. Please see the document 8000 Intelligent Network Manager Third Party
Hardware and Software Requirements for detailed requirements concerning database server
hardware.
2.3.1 The Role of the Database in 8000 Intelligent Network Manager
All inventory and configuration data of the managed network elements are stored in the 8000
Intelligent Network Manager database. This kind of complete documentation about the network is
created automatically when different 8000 Intelligent Network Manager tools, all of which use thedatabase, are used for building, configuring and monitoring the network.
Examples of data stored in the database are:
• line and control cards
• interface modules
• interface configuration: layer 1, 2 and 3 parameters, VLANs etc.
• protocol (BGP, OSPF, DHCP, ARP...) configuration
• service (circuits, VPNs, pseudowires...) configuration
• equipment and service fault information (resulting from fault polling)
• performance data collected from the network elements.
8000 Intelligent Network Manager database can be used for pre-planning networks, configurations
and services before they are actually implemented. It is possible to plan the network topologywith network elements and trunks that do not exist in real world yet. It is also possible to create
the detailed configuration and parametrization of non-existing nodes in the database and use
these nodes in pre-planned services. After the pre-planned nodes and trunks are in place, it is
a straightforward task to bring the pre-planned parameters from database to the nodes and to
implement the pre-planned services utilizing them.
Note, however, that dynamic information, such as the routes in the default routing tables and VRFs
learned through the BGP/OSPF routing protocols, is not stored in the database.
2.3.2 Separate Performance Management Database and PerformanceManagement Table Partitioning
Network elements, such as 7100, mTera, 8600 and 8800 NEs, with thousands of physical and virtual
interfaces, as well as IP VPNs, TE tunnels and pseudowires generate a large volume of 15-minute performance monitoring (PM) data. The database space reserved by the PM data may be from 10
to 1000 times bigger than the space reserved by network configuration data. Due to this fact, PM
data has a limited retention period – old PM data has to be removed daily to free the database
space for the new data.
As the size of PM data tends to grow very rapidly, the separate PM database and PM table
partitioning features keep the 8000 Intelligent Network Manager configuration database compact
and fast when the PM data collected one day exceeds 10-20 million rows.

Fig. 34 Separate PM Database
Benefits of the separate PM database are the following.
• Smaller main database footprint means that main database backups and maintenance routines
work much faster.
• When PM database is located on its own server or in its own physical storage, PM operations donot affect main database input/output.
• 8000 Intelligent Network Manager opens dedicated database connections to the PM database,
which means that, e.g. long-running or complex PM reports do not interfere with other activities.
• Warm/hot standby works much faster as there is no need to replicate the PM data.
• It is possible to put different optimization goals on the main and PM database.
Benefits of the PM table partitioning are the following.
• Faster PM reports
• Very fast and ef ficient clean up of the old PM data
The separate PM database is currently supported to be created only on the same physicalserver as the primar y database. Within this server, it is recommended to locate the separatePM database in its own physical storage.

2.4 Communication Server
2.4.1 General
A Communication Server is required for managing the nodes integrated into the 8000 Intelligent
Network Manager. The Communication Server sends cross-connection, pseudowire and other
configuration commands to the nodes, fetches configuration snapshots, transfers ESW files, polls
the nodes for faults and performance data, etc. It also maintains real time clock settings for thosenode types that do not have NTP as an option. Note that e.g. all 8600 nodes support NTP, and thus
Communication Server will not update their real time clocks.
A domain concept is used to refer to a system or network which internally uses the same
management protocols and paradigms. A network consisting of 8600 nodes is an example of such a
domain. Nodes in this kind of a domain are accessed via an adapter or adapters in a Communication
Server. The adapters perform the conversion of information between 8000 Intelligent Network Manager and the domain, i.e. the 8600 domain in this case. The adapter is plugged into the
southbound interface of 8000 Intelligent Network Manager and it communicates with the nodes
either directly or by using a vendor specific mediator, proxy or element management system as a
gateway. In the case of 8600 nodes, the adapter communicates directly with the nodes using a
protocol called BMP and with SNMP.
There can be several Communication Servers per domain, each running its own set of adapter
processes. Communication Servers are associated with areas, so that each Communication Server
handles the nodes of those areas that have been assigned to it. This allows 8000 Intelligent Network
Manager to manage very large networks.
For each area, it is also possible to define a backup Communication Server, which assumes the
responsibilities of the primary server if the primary server fails. Communication Servers thus provide a fully redundant system in node communication.
Please see the document 8000 Intelligent Network Manager Third Party Hardware and Software
Requirements for detailed requirements concerning Communication Server hardware.
A separate licence is needed for each of the adapter types deployed in the CommunicationServer. In addition, separate licenses are needed also for each network element deployedin the network.
2.4.2 Managing the Communication Servers
The supervisor process controls the server functionality. It can be monitored and controlled through
a graphical user interface, the Server Monitor tool. The Server Monitor tool shows all the services
and processes that are installed in the server, and their current status. Through the Server Monitor
tool the user may start and stop individual services and restart/shut down the entire server.
The operator can configure Communication Servers by using the Communication Server
Parameters dialog in Network Editor. This dialog allows the setting of the name of the server and
the computer LAN name, its IP address and the backup level, as well as the adapters used by the
server. The Communication Server uses a communication adapter for each network element type or
protocol it supports. Some Communication Server parameters are defined in the configuration file.

2 8000 Intelligent Network Manager Components and Architecture
The Communication Server can use the 8000 Manager Trace Utility to log its run time prompts,
warning messages and errors. The Trace Utility is a system through which different 8000 Intelligent
Network Manager tools generate log messages that are of help especially in the diagnosis of
problem situations.
2.4.3 Fault Management in Communication Servers
Fault management in 8000 Intelligent Network Manager Communication Servers is divided into
several dedicated processes. The polling controller creates poll jobs specified by polling policies.
The generic poller process uses adapters to poll faults from network elements. The faults are filtered
and reclassified, and then stored in the database. Polling policies can be edited in the Polling
Policies dialog in Network Editor.
2.4.4 Backup Monitoring in Communication Servers
The Communication Server can back up the functions of other Communication Servers in a
multi-server environment. The backup level can be configured in Network Editor. Possible values
for the backup level are Not Used, User Def and Auto.
The backup functionality is implemented by backup processes that run in each Communication
Server of the system. They poll each other to detect the loss of another server. If a server is lost, areas
are moved to running servers. This happens automatically if the backup level is defined as Auto for
the servers in the Communication Server Parameters dialog. It is also possible to set the backup
level to User Def and define the preferred Backup Communication Server in the Area Parameters
dialog in Network Editor. It is only possible to define one backup server for each area. On the other
hand, if both primary and backup server of an area fail the communication responsibility for the area
is moved to one of the running servers, as far as at least one running server exists.
2.4.5 Communication with Network Elements
There are two major ways of arranging the management communication:
• Outband management: There is a separate network for management communication, com-
pletely separate from the network that the 8000 Intelligent Network Manager installation in ques-
tion is managing. The external management communication network must provide IP connec-
tivity between the Communication Servers and all managed network elements. The advantage
of using outband management is that the management connectivity is not dependent on the state
of the managed network.
• Inband management: Communication between Communication Servers and managed nodesgoes through the managed network itself. The advantage here is that maintaining a separate
network for management communication is not needed. The disadvantage is that management
communication to the nodes is dependent on the state of the managed network.
When using inband management, care must be taken that configuration changes made in anetwork element do not cut the management connectivity to the node itself, or to any other nodes to which the management communication goes through the changed node.

2 8000 Intelligent Network Manager Components and Architecture
2.4.6 Element Adapters
5500 Adapter
The 5500 Adapter is needed for communicating with the 5500 Series network elements. The
communication to the network elements is done using TL1. The EMS for 5500 network elements
utilizes a similar architecture than the 7090, 7100 and 8800 EMS.
6300 Adapter
The 6300 Adapter is needed for communicating with 6300 Series nodes. The communication to the
network elements is done using a protocol called LMIP (Local Management Information Protocol),
which is based on the CMIP protocol (Common Management Information Protocol). For some partsof the communication, SNMP (Simple Network Management Protocol) is used as well. LMIP is
transported using the OSI TP4 protocol or, in case of the newest NE feature packs, using the IPTCP protocol, while SNMP is transported using the IP UDP and TCP protocols. In addition, each
Communication Server also runs a so called Gateway Process, which act as communication gateway
between the 8000 Intelligent Network Manager workstations and the control network of the 6300
nodes. The Gateway Processes are used by the 6300 Craft Terminal tools when they are used for node management purposes on the workstations.
7090 Adapter
The 7090 Adapter is needed for communicating with 7090 Series network elements (e.g. 7090-25
CE and 7090-45 CE). The communication to the network elements is done using SNMP. The SNMP
protocol is mainly used for collection of faults from the network elements.
The launching of 7191 Craft Station for 7090 network elements utilizes the Gateway Process in
Communication Server. This enables the 8000 Intelligent Network Manager workstations and 7090
network elements to be located in separate LAN segments.
The EMS for 7090 network elements utilizes a multi-tier architecture (based on Java Remote
Method Invocation) for communication between the workstation, Management Server and
Communication Server. The 7090 EMS component on Communication Server uses SNMP to
communicate with the 7090 network elements. Note that the EMS does not support the 7090-05 CE,
7090-07 CE and 7090-15 CEM network elements.
7100 Adapter
The 7100 Adapter is needed for communicating with 7100 Packet Optical Transport Series network
elements (7100 OTS and 7100 Nano) and mTera Universal Transport Platform network elements.
The protocol used in the communication to 7100 and mTera elements is TL1 (Transaction Language
1) and SNMP protocol for the packet subsystem. TL1, developed by Telcordia Technologies on top
of TCP, is a cross-vendor, cross-technology man-machine language. It is widely used to manage
optical (SDH/SONET) and broadband access infrastructure especially in North America.
The launching of 7191 Craft Station for 7100 and mTera UTP network elements utilizes the Gateway
Process in Communication Server. This enables the 8000 Intelligent Network Manager workstations,
and the 7100 and mTera UTP network elements to be located in separate LAN segments.

2 8000 Intelligent Network Manager Components and Architecture
The EMS for 7100 and mTera UTP network elements utilizes a multi-tier architecture (based on
Java Remote Method Invocation) for communication between the workstation, Management Server
and Communication Server. The 7100 and mTera EMS component on Communication Server uses
TL1 and SNMP to communicate with the 7100 and mTera UTP network elements.
8100 Adapter
The 8100 Adapter is needed to communicate with 8100 system nodes. Communication to the nodes
is based on a management protocol called the DXX protocol. The 8100 Adapter must be run in a
dedicated communication server, this server is also referred to as a DXX Server. No other adapters
may be run in a communication server running with the 8100 Adapter.
8100 EFM Adapter
The 8100 EFM Adapter is needed for communicating with the 8100 EFM network elements. The
communication to the network elements is done using SNMPv2. The SNMP protocol is mainly usedfor collection of faults from the network elements.
The EMS for the 8100 EFM NEs utilizes the Gateway Process in Communication Server.
8600 Adapter
Communication Servers communicate with 8600 network elements using BMP as the
communication protocol. This is an ef ficient, object-oriented management protocol, which is
specifically designed for managing data network elements. BMP uses UDP as a transport protocol,
although in the latest NE feature packs, TCP is also supported as a transport protocol. BMP has the
power of expression that makes it capable of making complex configurations in an effective way,
but is still relatively lightweight and simple compared to other powerful management protocols such
as CMIP. The 8600 Adapter is used for communicating with the 8600 network elements using the
BMP protocol. Third party management tools can read information from the 8600 network elements
using the SNMP protocol and the 8000 Intelligent Network Manager also uses the SNMP protocol
to collect performance statistics from the 8600 network elements.
8800 Adapter
The 8800 Adapter is needed for communicating with 8800 Smart Routers. The communication to
the network elements is done using SNMP. The SNMP protocol is used both for configuration of
the 8800 Smart Routers as well as for collection of the faults from the network elements. The
performance history data is collected using FTP.
The EMS for 8800 network elements utilizes a multi-tier architecture (based on Java RemoteMethod Invocation) for communication between the workstation, Management Server and
Communication Server. The 8800 EMS component on Communication Server uses SNMP to
communicate with the 8800 network elements
Generic SNMP Adapter
The Generic SNMP adapter is used for communicating with third party nodes supporting the SNMP
protocol and standard SNMP MIBs.

CLI Service
CLI Service is needed for communicating with 8600 network elements when no BMP interfaceis available in the network element.
ADNS Service
ADNS Service is used for detecting the appearance of newly deployed nodes in the network. ADNS
Service is a part of the automated deployment feature.
Deployment Service
Deployment Service is DHCP –like service for assigning initial IP address to newly deployed nodes
in the network. Deployment Service is a part of the automated deployment feature.
2.5 Management Server
Management Servers run most of the 8000 Intelligent Network Manager business logic. This is
divided into service processes. The placement of different services in the server computers is
flexible: most of the services can be run in the same server or alternatively different services can be
located in separate servers. It is also possible to have multiple servers running a single service in an
installation where the number of workstations is very large. The clients can be configured to use analternative Management Server if the preferred server is unavailable. The setup application offers a
number of pre-configured sets of services for ease if installation and configuration.
The currently installed services and their status can be seen in the Server Command Center - 8000INM dialog.

2.5.1 Service Processes
Some services must have only one copy running at a time, while there can be several copies of others
running simultaneously, if the service names and workstations have been configured appropriately.
The unique services with only one possible instance are described in the table below.
Service Description
Packet Loop Test Service Allows scheduled and immediate testing operations
Running more than one instance of the above services in the system will lead to error situations.
The rest of the services also depend on each other. As a general rule, there should be at least one copy
of each service installed and running in the management system for the system to be fully functional.
These services are described in the table below.

2.5.2 Using Multiple Service Instances
If a Management Server fails, the same services can be activated in other Management Servers by updating their configuration files (or by reconfiguration) or clients can be preconfigured to
automatically revert to use another management server if the preferred server is unavailable.
2.5.3 Satellite Service
The Satellite Service serves an array of workstations, see the figure below. The Satellite Service
was previously known as the Gateway server.
Fig. 36 Management Server Running Satellite Service in 8000 Intelligent Network Manager
Workstations do not have a direct connection to the database as their access to the database is
multiplexed through the Satellite Service. Workstations are connected to the Management Server
running the Satellite Service with routed LAN. Individual remote clients and their connection to
the database can be better tolerated because the 8000 Intelligent Network Manager tools of the
workstations cannot lock directly onto the database tables. The Management Server serializes
transactions to the Database Server.

2 8000 Intelligent Network Manager Components and Architecture
Workstations use the services of the Database Server, Management Servers, Communication Servers
and Recovery Server through the Satellite Service.
2.5.4 Fault Service
The Fault Service is run in the standard Management Server. It continuously polls the database
for changed faults, processes the fault data and performs service fault mapping. When the Fault
Service detects changed faults, it analyzes the fault data and informs Fault Management System
of the change in the fault condition. The Fault Service maps the raw fault data both to the basic
network elements, e.g. nodes and trunks, and to the higher-level objects, e.g. circuits, customers and
service categories. Fault Management System listens to the notifications from the Fault Service andinvokes fault queries for different objects under fault monitoring.
The Fault Service provides services for several workstations in the system, and there can be several
Fault Services running in the same system.
2.5.5 Northbound Interface
8000 Intelligent Network Manager can be integrated into the operator's OSS system by using the
Northbound Interface. The level of this integration as well as the exact OSS components to integrate
with will vary a lot from one operator to another. To address these needs 8000 Intelligent Network
Manager provides a framework which supports implementing a number of northbound interfaces for
different purposes, e.g. fault management, VPN provisioning etc.
MTOSI Adapter
TM Forum’s Multi-Technology Operations System Interface (MTOSI) effort has the goal of defining a unified open interface to be used between Operations Systems (OSs), where an OS isany management system that exhibits Element Management Layer (EML), Network Management
Layer (NML) and/or Service Management Layer (SML) functionality as defined in the ITU-T
TMN model. 8000 Intelligent Network Manager provides a northbound MTOSI interface using
traditional web-services technologies (WSDL/SXD and SOAP/HTTP) to implement a combination
of standard, pre-standard and proprietary operations. The interface is based on the MTOSI Release
2.0 specifications with some proprietary extensions for IP/MPLS based services as well as testand diagnostics functions.
Supported functionality includes the following.
• MPLS pseudowire provisioning (SAToP and Ethernet PWs)
• IP VPN provisioning
• RSVP-TE tunnel provisioning
• Port configuration
• Connection testing (VCCV LSP ping, ATM ping, IP Ping, Ethernet ping and traceroute)
• Port status checks
• Port and pseudowire loopbacks
• IP static route configuration
• LDP neighbor configuration

• NE inventory retrieval
• Network element provisioning
• Ethernet OAM (802.1ag and Y.1731) management
• IEEE 1588 synchronization management
• Generic extension interface (calling native 8000 Intelligent Network Manager macros through
MTOSI)
The supported elements include 8605 Smart Router, 8609 Smart Router, 8611 Smart Router, 8620
Smart Router, 8630 Smart Router and 8660 Smart Router.
The MTOSI Adapter can be configured as part of the NBI Server configuration.
SNMP NBI Adapter
8000 Intelligent Network Manager provides an SNMP interface for the fault system. Both SNMPversion 2 and SNMP version 3 are supported. The SNMP NBI Adapter can be configured as part of
the NBI Server configuration.
2.6 Recovery Server
Recovery Server provides facilities to restore user communication links if trunk or node faults occur
in the 8100 system network. The Recovery Server is used for circuit and trunk protection.
Recovery Server is optional and runs on a dedicated recovery computer. If there is only one DXXServer in the system, both Recovery and DXX Servers can run in the same computer.
It is possible to install two Recovery Servers in the 8100 network to increase reliability. In case of an
unrecoverable failure of the active Recovery Server (e.g. LAN failure, physical damage causing PC
hardware failure, electricity break) the backup Recovery Server will take over the recovery support
for the 8100 network. In case of a hardware or software update, the backup can also replace the
primary Recovery Server during the update operation.
Recovery Management System uses a single centralized Recovery Server that provides the recovery
functionality. However, it is possible to switch servers at any time. Server switching operations can
be initiated from Recovery Control Program if you have the required privileges.

network, if needed.
3.2 Basic Package
3.2.1 Network Editor
Network Editing Tools are used for building, viewing and editing the model of the 8000 system
network stored in the database. Network Editing Tools comprise Network Editor as a top-level
window from which you can launch the other tools, including Node Editor and ID Interval Editor.
The objects stored in the database represent the management view of the hardware and software
elements and the interconnections between them. Network Editor displays many of these objects and
connections graphically. It has many text-based dialogs for viewing and changing the parameters of the database objects. In a few cases Network Editor communicates with the hardware elements. A
special feature of Network Editor is the Toolbox, which floats on the Network Editor screen. It is a
collection of panels that allow new objects (nodes, trunks, locations and networks) to be created,
existing objects to be selected and moved, and independent tool sessions to be launched.

Fig. 37 Network Editor Window
Representation of Network
Network Editing Tools represent the network in the Navigator Tree, List and Network View
windows, and switches in one or more Node windows.
The Network View window represents a graphical view of the whole network, or the view can be
zoomed and scrolled to show a part of the network. In this window the nodes, trunks, locations andnetworks are represented by small graphic representations, symbols. Each object refers to a specific
item of hardware, a logical object created for the purpose of managing the hardware, or external
equipment connected to it. For example, each switch is represented by a graphic resembling the
front view of the switch subrack. A location is a symbol representing a group of nodes and trunks
that interconnect the network elements, usually all located in close proximity. A location can be
opened to view the subnetwork it represents. Locations can be nested, i.e., a location can contain
another location.
The Navigator Tree View window represents a navigational view of the whole network. Objectsare grouped according to their type and position in the topological hierarchy. The number of visible
objects in the window can be limited by using subdivision groups and filters. The List View window
gives a more detailed report view of object properties.

3 8000 Intelligent Network Manager Application Packages
Two other types of Network window can be opened. The secondary network window displays an
overview of the network. A location window can be opened for any location object to display the
network of network elements in that location.
Trunk Symbols
Connections between network elements are represented by a connecting line, referred to as a bundle.
On this line, there are small symbols displaying the trunk type. More than one trunk can be placed
upon a connecting line and to represent multiple trunks between the same pair of end network
elements.
View Options
The types of objects displayed and how they are displayed can be controlled by a number of view
options.
The network view options include the following:
• Customer view
• Trunk view
• Network element view
• Selected area
• Unbound network elements
• Object labels
The network element level views include the following:
• Subrack or shelf view
• Module view
• Interface view
• Network element tree view
A Node window can be opened for any switch by launching a Node Editor session. The Node
window displays an overview of the subracks of a switch and a picture of a subrack with its cards
and interface modules.
State Logic
The main target of the 8000 Intelligent Network Manager State Logic is to allow the user to
pre-design the 8000 system networks in the database even if no hardware exists. State changes are
initiated by the user. The state of the object implies certain assumptions about its configuration
and behavior when managed.
The states have the following meaning for the objects in a network element:

same as installed, but end-to-end management and network level management
software considers this object to be suitable for production use.
8800 Network Element States
planned 1 Object is assumed not to exist physically. As a general rule, configuring the
object will only affect the database representation.
installed 2 Configuration operations will affect both database and network element. The
specific hardware object may or may not exist physically. Alarms are not
monitored for the object.
in use 3 Object is meant to be used in production. From configuration point of view,
this is the same as installed, but end-to-end management and netwo rk level
management software considers this object to be suitable for production use. For
objects representing physical resources, the system has ensured, at some point in
time that the physical resource is in place. Alarms are monitored for the object.
Usually, planned is seen as the lowest and in use as the highest state. When updating the state from
planned to installed or in use, the parameters are copied from the database to hardware. Parameters
that belong to the whole network element instead of a certain interface or other physical object
are associated to the state of the control card.
Node Editor
Node Editor is a tool for defining the provisioning of network elements and defining and viewing
interface uses and the bindings of interfaces to trunks and nodes.
There are two ways to add new cards and modules into the network element. This can be done
through a pop-up menu or with the help of toolboxes of available card and module types. A Settings
dialog allows the state of objects to be changed. Various Node Manager windows can also be
opened from Node Editor.
Node Editor provides two views for displaying network element furnishing: graphical view and
tree view. The graphical view shows subracks/shelves, cards and interfaces of the node as a picture.
The tree view shows the same information in a tree structure, but shows also binding information for the interfaces of the node. In addition to the two switch views, there is a network view showing
the trunks and other nodes attached to the node being viewed.
A pop-up menu is available both for the graphical view and the tree view.

ID Interval Editor
ID Interval Editor is a tool for defining the range of valid IDs for each class of object that Network
Editor and other tools can add to the database, e.g. node IDs and trunk IDs.
Power Balance Application
The Power Balance application is used for estimating power consumption and power balance
(surplus or shortage) of 8660 Smart Router and 8630 Smart Router. The Power Balance Overview
dialog displays power estimates of several network elements whereas the Power Balance Details
dialog shows a detailed power report for a single network element. The power computation is
based on the network element inventory data stored in the 8000 Intelligent Network Manager
database. The Power Balance application gives just a rough estimate of the power figures, more
reliable estimates can be calculated manually as instructed in Tellabs® 8600 Smart Routers Tellabs®
8660 Smart Router Reference Manual and Tellabs ® 8600 Smart Routers Tellabs® 8630 Smart

QoS Settings Tool
The QoS Settings tool is used for setting up various Quality of Service related parameters in allinterfaces of the network. The parameters can either be set for one interface at a time or for a
point-to-point trunk, in which case identical parameters are set to both the end interfaces of the
trunk. This tool can be opened from Node Manager main window and Node Editor for an interface
and from Network Editor for a trunk.
The tool provides support for templates that make it possible to define a QoS setup suitable for
certain kinds of interfaces/trunks in a network, to name this template and to apply it for any number
of interfaces or trunks. Applying an existing template to each interface or trunk is done by opening
the QoS Settings tool for the interface or trunk, selecting the template from a drop-down list and
clicking a single button in the dialog. The templates are stored in the 8000 Intelligent Network
Manager database and there can be any number of them.
The QoS parameters supported by the tool include:
• Bandwidth Reservation: parameters related to RSVP capacity reservations for traf fic engineered
LSPs
• Policer: service class-specific policers for traf fic entering the node through the interface in ques-
tion
• Shaper: service class-specific shapers for traf fic leaving the node through the interface
• Queue: queuing parameters for the different service classes for traf fic leaving the node through
the interface
• Mappings between E-LSP exp bits/Ethernet priority bits and the service classes used by the op-
erator. These affect both ingress and egress traf fic.

Synchronization Monitoring Tool
Synchronization Monitoring Tool is used to monitor the synchronization clock flow throughout the
8100 system network. It can also monitor 6300 nodes that are managed with 8000 Intelligent
Network Manager. This tool can be used, for example, to check that the synchronization network is
configured as planned and to locate faults (e.g. loops) in the synchronization network.
There are two possible methods of monitoring synchronization clock signal distribution in the
network. The first is Default Synchronization Path, and the second is Current Synchronization Path.
The default path shows where the synchronization clock signal is expected to come from, and
the current path shows where the synchronization clock signal is actually coming from. Tracing
can be done to one node at a time.
Enhanced Reporting Tool
The Enhanced Reporting tool provides a central and flexible location for querying the 8000
Intelligent Network Manager database for inventory and services.
• Custom queries can be built by setting various filters on any column in a given report.
• Customized queries may be saved for reuse and shared with other users.
• Once saved, queries can be scheduled for regular execution in Scheduling Center, with results
e-mailed to users.
• Report output may be exported to multiple formats, including CSV and PDF.

3.2.2 Node Manager
8100 Node Manager and 8600 Node Manager
Node Manager provides facilities to manage the network elements: switches, cards and interfaces.
The element management facilities include parameter setting, fault monitoring, consistency
checking and templates. Node Manager can be opened from Network Editor.
Node Manager is a collection of tools that are used for setting parameters for network elements
and monitoring the existing parameter values.
Node Manager shows the actual topology of the network element and which cards are active and
in use. With Node Manager it is also possible to add/remove cards and modules and change their
states (planned, installed, in use).

Preplanning
Preplanning makes it possible to create elements and set parameters for them in the planned stateindependently of the state of the physical hardware. Later, when the state of the elements is raised
from planned to installed or in use, the parameters are copied from the database to real hardware
elements. In normal use, when hardware communication exists and the element is in the in use state,
Node Manager shows the actual layout of network elements and allows the user to set parameters
for hardware values.
Templates
Templates are used to store a named set of interface parameters to the database. The use of templates
helps the user to set interface parameters faster and more accurately. The system administrator can,
for example, make an interface parameter template which the other operators can make use of later.
Node Manager Tools
There are several different tools in Node Manager. These include, among others, the following:
• Consistency Checker for finding and resolving inconsistencies between database and node. In the
Consistency Checker dialog it is possible to select for which topology elements the consistency
check is done.
• Node Autodiscovery for reading a node topology hierarchy to the database. Autodiscovery can be
initiated when a new network element has been installed or as an incremental discovery operation
when line cards and modules have been added to the network element. The network element must
be added to the database before initiating the autodiscovery operation.
• IP Routing Table for defining routing table
• MPLS for defining MPLS behavior
• IP Host for defining protocol parameters
• BGP-4 Router for defining BGP parameters and creating neighborhoods
• QoS Settings for defining Quality of Service parameters for the node
• ACL for defining Access Control Lists
• OSPF Router Process for defining OSPF router behavior
• OSPF Area for defining OSPF area parameters
• IS-IS Router Process for defi
ning IS-IS router behavior • Route Map for defining Route Maps

3.2.4 Fault Management System
Fault Management (FMS) is used for monitoring and reporting the fault status in the 8000 system
network. The basic function of Fault Management System is fault monitoring, which includes thecontinuous supervision of network elements. The Communication Servers and DXX Servers collect
the fault data from network elements (Communication Server used in the text subsequently to refer
both to DXX Servers and Communication Servers). Each server is responsible for gathering fault
events from one or more network areas (a collection of network elements). The detected fault events
are filtered, if necessary, and transferred to the system database. The network fault status stored in
the database is, in turn, continuously monitored by Fault Servers in the system.
This arrangement offers a real-time fault view of the monitored network to the network operator.
Detected fault events are attached to proper object symbols (trunks, user access points, network
element kernel parts, etc.) in the Fault Management windows. The appearance of these symbols
directly indicates the severity of faults in the corresponding network elements.

Fig. 53 Main Window of Fault Management System
Fault Monitoring Principles
Fault monitoring is automatically started when the state of the network element is changed to in use.
Fault monitoring is based on network fault polling. 'To poll' means to perform a status query fromthe network element. Whenever a change in the network element fault status is detected, detailed
fault information is provided in the faulty network element itself. This information is read by the
Communication Server and transferred to the database. Communication Server obtains the fault
data through an adapter. Depending on the case, the adapter can interface with another managementsystem or contact the network element directly. Note that only a single poll has to be performed for
a network element because all the new faults and cleared faults are polled at the same time. By thisarrangement a single Communication Server can take care of the fault polling of a relatively large
area. The Communication Server polling parameters, like fault and network element ping polling
period, are configured in the Polling Policies dialog in the Network Editor.
Fault notifications, initiated by network elements, are used for speeding up the detection of new or
changed faults. When there is the first change in a fault situation of the node since the last time the
node was polled, a fault notification is sent to 8000 Intelligent Network Manager. After receivingthe notification the node that sent the notification is polled immediately – or almost immediately
if there are notifications coming from several nodes in a short period of time – even if it is not
yet that node's turn in the normal polling cycle.

http://slidepdf.com/reader/full/8000-inm-sr60-system-description 89/171
3 8000 Intelligent Network Manager Application Packages
In addition to the network fault status polling and notifications, also the consistency between the
system database (network element and card configurations) and the actual values stored in hardware
are checked periodically. Any inconsistencies detected during the checking are reported via the fault
management user interface.
The faults reported by a card are ignored in case the installation state of the faulty interface or the
card itself (card level faults) is below the configured threshold value. This value can be set to
installed or in use. By this method the faults generated during equipment installation can be omitted.
A card is under fault monitoring as long as it exists in 8000 Intelligent Network Manager. All
possible active faults and the card fault history are deleted when the operator deletes a card.
Fault filtering allows modification of the rules for including and excluding certain types of faults
into and from the database. Those faults already in the database can be viewed by the Fault
Management System windows.
Fault Management Windows
The fault management user interface contains five basic fault monitoring windows, the Network ,
Network Element, Bundle, User Access and Unit window. These windows follow the fault
condition in the supervised network in real time, which means that whenever the windows are open
at the workstation, new faults are indicated as soon as the Communication Server has detected them.
The faults are attached to proper fault management object symbols in these windows. The Fault
Management System objects in the windows are the following:
• Network
• Location
• Network element
• Subrack
• Bundle (trunk group between two network elements)
• User access group (user access interfaces of a single network element)
• Trunk
• Card
• Card block (card physical block objects )
• Card logical block (groups of physical block objects)
• Interface (interface of a card)
• Components
The appearance of the object symbol in the window (color coding, blinking status) directly reflects
the fault state of the object. The object is said to be in the normal state when it does not contain
any fault events at all. For example, a user access group object of a network element is in the
normal state when all the user access interfaces in the network element are operating normally.
The object is alerting if it contains at least one unacknowledged fault event. Note that normally
the object is alerting as long as the fault remains unacknowledged, regardless of the fault state in
the network (active or inactive). After the operator has acknowledged the fault, the object state is
changed to faulty. When the fault is fixed, the object state is changed to normal again. If an object
contains several faults, the layout of the object symbol in the window is determined according to
the most serious fault event.

3 8000 Intelligent Network Manager Application Packages
In the Fault Management System there are two different card block types: physical block object and
logical block. A physical fault object contains a physical fault block and block class numbers, and
represents real hardware objects where faults originate from. The logical fault block is used to group
several physical fault block objects into a certain logical group.
In addition to basic fault monitoring windows, there are Service Fault Monitoring related windows:
Service Fault Monitoring (SFM) window and Service Fault window. Service Fault Monitoring
enables the real time supervision of all services, i.e. IP VPNs or pseudowires that are assigned to a
certain Service Category. A Service Category is a collection of pre-selected services. It is possible
to configure Service Fault Monitoring so that only the selected service categories are displayed.
In this mode, symbols are displayed in the order they were selected. In addition to the predefined
categories, an operator can select dynamically Customers to be taken under monitoring. Thefault status of categories and customers is displayed in the Service Fault Monitoring window.
The All Faulty Services symbol can be added to the lower right-hand corner of the window. This
symbol represents the total fault status of all services. By default, the selected service categories and
customers are saved on the configuration file and thus remembered. This means that next time the
previous view is automatically restored. One workstation or Fault Server can be selected to saveand update all faulty services in the database.
All faulty services and their fault status details of the corresponding category or customer are listed
in the Service Fault window. The appearance of Category and Customer symbols follow the same
characteristics as other objects in the FMS windows (color coding and blinking status directly
reflects the fault state of the object). From the Service Fault window an operator can open a Service
Fault Report window concerning a specific service and its faults.
The Critical Element Fault Monitoring window enables the real time supervision of faults related
to a particular trunk or node type. The window shows the selected trunk and node types with the
type label texts below the symbols. In the partitioned networks, the fault statuses of the trunk and
node types are shown for the selected regions. It is also possible to see the fault statuses which aresummed from all network faults without dependence on the regions. For more information on
partitioning, refer to 3.11 Partitioned Package.
The Fault Management System view can also be reduced to show only faulty network objects. This
option is very useful in large networks when only a small number of objects are faulty.
A warning beep facility can be activated at the workstation to give an audible warning when the
fault status in the network has triggered the preset severity level.
In addition to the fault monitoring facilities, the Fault Management System user interface also offers
other supporting tools. The fault view mode (maintenance status/service status/mask status) for
different types (network element/trunk/view/alarm/fault) can be defi
ned. Fault reports withseveral search conditions can be retrieved from the database and printed, if necessary. Old events
can be deleted from the fault history when no more needed. The Trouble Ticket facility can be
used to record information on network service problems. Any inconsistencies detected between
the system database and the actual network hardware can be studied in more detail. Tools for
defining the fault filtering characteristics also exist.
Fault Report Application
The Fault Report application can be used for monitoring individual faults and faulty services withsophisticated summarization, filtering and prioritization functions. The application has flexible
layout architecture, i.e. the windows can be dragged out from the main view, or moved and resized
within the application. Additionally, the windows can be tabbed together.

The Fault Report application can display numerous fault types, i.e. element faults, component
monitoring faults and faulty services, in the same window. The different fault types are shown in
their own fault perspectives providing different views to the fault data. By default, the Fault Report
application includes five different fault perspectives.
The Element Faults, Faulty Services and Component Monitoring perspectives can contain
the following subwindows.
• The main fault report window displaying the fault report rows. This window shows all report
rows according to the current perspective settings.
• Multiple summary windows showing graphical presentations of fault summaries. The summary
calculations are always based on the current perspective settings, and reflect the main fault report
window.
• The Fault Details window displaying a detailed view of the selected row in the report.
• Optional fault report subwindows showing related faults based on the selections made, e.g. the
element faults related to the selected faulty service or node faults. The selections made in thesummary windows are also applied to the fault report subwindows.
Fig. 54 Fault Report Application with Element Faults Perspective
The Fault Status and Fault Summary perspectives contain summary graphs of the overall
situation, e.g. the amount and severity of network element faults, faulty services and component
faults (server faults).

Fig. 55 Fault Report Application with Fault Status Perspective
Each fault perspective includes a predefined set of fault views affecting the fault data within the
perspective. Fault views can be used for filtering and sorting the fault data. The fault views are based on priority calculations whose results are shown in the Priority column as a star rating.
When using the fault views, every fault has a rating from one (lowest) to five (highest) stars
indicating its importance. By default, all data is shown as non-prioritized and sorted according to
the On-Time column.
Additionally, the fault perspectives contain a predefined set of summary windows presenting
summarized fault data in the pie and bar charts. The summary windows help to detect abnormalfault changes. Clicking a graph item displays detailed fault data in the fault report subwindow.
By using dynamic filters, the most significant faults currently existing in the network can be viewed
more thoroughly. Filtering affects all windows in the current perspective. These dynamic filters
are for temporary use only, and they are not permanently stored.

Fig. 56 Dynamic Filtering View
In the Fault Settings dialog, report types and time settings can be selected for the fault perspectives.
The layout settings of the Fault Report application can also be configured in this dialog. The fault
reports and summary graphs have their own settings. Many visual aspects, e.g. coloring and themaximum number of items to be shown can be configured. Additionally, it is possible to enable or
disable fault change messages for the reports and the summary graphs.
Fault Acknowledgment
Each fault event must be acknowledged. The fault acknowledging is either performed by the operator
or automatically by the system. When the fault is acknowledged, the alert indication (i.e. blinking)
stops. Alerting is thus active for an unacknowledged fault event if the fault itself has disappeared.
Only after the acknowledgement is performed and the fault is fixed in the network, the corresponding
object returns to the normal state and the fault event can be transferred to the fault history.
Fault Filtering
The purpose of fault filtering is to make it possible to fine-tune the fault management to meet
different needs. Faults that are filtered out (masked) are not stored in the database. If a fault is not
filtered, it is stored in the database. Those faults that are in the database can be later dynamically
view filtered in the Fault Management user interface.

Special Concepts Used in FMS
Fault Status Indication
A fault event reported by a network element contains the fields listed below.
The severity status has four categories:
• Critical
• Major
• Minor
• Warning
The maintenance status has three categories:
• Prompt Maintenance Alarm (PMA)
• Deferred Maintenance Alarm (DMA)
• Maintenance Event Information (MEI)
The maintenance status is converted from severity values in the following way:
• Critical mapped to Prompt Maintenance Alarm (PMA)
• Major mapped to Deferred Maintenance Alarm (DMA)
• Minor mapped to Maintenance Event Information (MEI)
• Warning mapped to Maintenance Event Information (MEI)
The service status of a fault event has two categories:
• Service alarm (S)
• Non-service alarm (non-S)
The fault status categories are used in the color coding of the FMS user interface to indicate the
severity of fault events.
The coding of different FMS object states in the Fault Management windows is by default as follows:
normal object Static color code:- CYAN for non-faulty objects
alerting object Blinking color code:
- RED for PMA/S/Critical faults
- YELLOW for DMA/Major faults
- GREEN for MEI/non-S/Minor/Warning faults
faulty object Static color code
- RED for PMA/S/Critical faults
- YELLOW for DMA/Major faults
- GREEN for MEI/non-S/Minor/Warning faults

http://slidepdf.com/reader/full/8000-inm-sr60-system-description 95/171
3 8000 Intelligent Network Manager Application Packages
It is possible to define a different color coding for a workstation with the Configure Fault Colors
dialog. Note, however, that the 8000 Intelligent Network Manager documentation in general refers
to standard coding (red, yellow, and green) when fault colors are concerned.
If an object contains several faults, the object symbol status and color are determined in accordance
with the most serious fault event. The order, from the most serious fault to the least serious one, is
as follows:
• Alerting PMA/S/Critical
• Alerting DMA/Major
• Alerting MEI/non-S/Minor/Warning
• Static PMA/S/Critical
• Static DMA/Major
• Static MEI/non-S/Minor/Warning
• Normal
Note that you can select the layout mode to be based either on the fault maintenance status (PMA,
DMA, MEI) or the service status (S, non-S). It is also possible to separate acknowledgement
information from priority calculation in the Set Fault Status View dialog. Thus the order, from the
most serious fault to the least serious one, is as follows:
• PMA/S/Critical
• DMA/Major
• MEI/non-S/Minor/Warning
• Normal
3.2.5 Trouble Ticket
The objective of the Trouble Ticket facility is to record, manage and control the service problems
associated with networks, customers and elements. A trouble ticket is a form filled in partly by
the system and partly by the operators. Tools for creating, viewing, editing and deleting these
tickets are supplied.
First category tickets are opened for general problems that do not involve a customer or a network
element. A customer ticket is attached to a specific customer in the network. Typically, it is created
as a response to a customer complaint. A network ticket is assigned to a specific network element,
either a trunk or a card.

3.2.6 Accounting Management
Accounting Management is supported for 8100 network elements. Circuit connection time reports
are based on the circuit accounting data that the 8000 Intelligent Network Manager components
(Router, Circuit Loop Tests, and Recovery) produce during the circuit’s lifetime. The accountingdata contains information on all activation, deactivation, testing and recovery actions on the circuit.
3.2.7 Security Management
Operator Access Control
Before any network management operation can be performed, an operator has to first perform a
login operation. In the login, the operator is requested to enter the correct username/password pair.
Several username/password combinations can be created by an operator for different purposes. If
wished, the system can force the operators to change their passwords regularly. The system can also
be set to limit the number of failed login attempts. Each login and logout operation is recorded in an
audit log where they can be viewed by an operator with security privileges.

http://slidepdf.com/reader/full/8000-inm-sr60-system-description 97/171
3 8000 Intelligent Network Manager Application Packages
Privileges
A set of privileges is attached to each operator when the username of an operator is created. A privilege is a permission to use a network management application or part of the application. In most
applications, privileges are divided into separate read and write privileges, allowing an operator
to use an application either in a read-only mode (no permission to alter any data) or in a modify
all mode (altering data in the database is allowed). In the case of some applications, operators can
be given even more detailed privileges, i.e. an operator can use an application to perform certain
operations while some other operations are prohibited.
In a partitioned network, it is possible to give operators permission to only manage part of the
network (one or several regions). Even inside a region, it is possible to restrict operator privileges
only to the backbone or access level of a network. If wished, other parts of a network can be hidden
altogether from a specified operator. For more information on partitioning, refer to 3.11 Partitioned
Package.
Profiles
Privileges to use different network management applications are grouped to form an operator
profile. A profile can then be attached to any network operator or group of operators. By giving
the same profile to a group of operators it is easy to add or remove privileges to/from several
operators at the same time.
LDAP and RADIUS Authentication
It is also possible to authenticate users from a central LDAP or RADIUS server. This is beneficial
when the user needs access to several tools. The passwords of the users are managed centrally at the
LDAP or RADIUS server. The passwords need to be changed only once in the LDAP or RADIUS
server, instead of being changed in each of the tools where the users have access. In addition, an
8000 Intelligent Network Manager user profile is assigned to the users in the LDAP or RADIUS
server. The user profile defines the user authorization for each of the 8000 Intelligent Network
Manager applications.
3.2.8 Scheduling Center
The Scheduling Center tool is used for scheduling tasks in 8000 Intelligent Network Manager.
The following types of tasks can be scheduled.
• Script/command line tasks. Any type of operating system scripts and commands can be sched-uled.
• Maintenance tasks. The database maintenance tasks can be scheduled. The database requires
regular maintenance in order to function optimally. These are mandatory tasks, and a default
schedule is automatically installed.
• Remote maintenance tasks. Maintenance tasks for the replicate database can be scheduled
(mandatory if NMRS is used).
• Database polling. Certain types of data can be polled from the main tables to the secondary tables
for reporting purposes.
• Backup tasks. Database resiliency requires database backups to be taken in adequate intervals.
These are mandatory tasks, and a default schedule is automatically installed.

• Housekeeper tasks. Housekeeper tasks clean up obsolete data, monitor the Sybase database server
parameters and delete aged data. These are mandatory tasks, and a default schedule is automati-
cally installed.
• Web Reporter tasks. Web Reporter tasks can produce reports and collect trend data.
• Enhanced Reporting tasks. Reports can be scheduled and post-processed e.g. e-mailed.
• Stored procedure. The stored procedures can be scheduled.

3.2.9 OAM Management
The OAM Management tool is used for managing Ethernet operations, administration and
maintenance (OAM) functions, defined in IEEE 802.1ag and ITU-T Y.1731 standards. These
standards define a number of mechanisms and protocols for monitoring and testing Ethernet
connections.
• Continuity Check (CC) – Used for proactive OAM, i.e. for detecting loss of continuity or mis-
connections of an Ethernet connection.
• Loopback (LB) – Used for verifying connectivity of an Ethernet connection either between end-
points or between an endpoint and an intermediate point.
• Link Trace (LT) – Used as an on-demand OAM function for tracking the path of an Ethernet
connection, or for fault localization.

• Frame Loss Measurement (LM) – Used for measuring the frame loss experienced by an Ether-
net connection.
• Frame Delay Measurement (DM) – Used for measuring the frame delay and delay variation of
an Ethernet connection.
The OAM Management tool supports management of these mechanisms, as well as management of
the Ethernet OAM monitoring objects: Maintenance Domain (MD), Maintenance Association (MA),
Maintenance Association Endpoint (MEP) and Maintenance Domain Intermediate Point (MIP).
Fig. 59 OAM Management Tool
In addition to node-by-node management of Ethernet OAM, OAM Management supports also
service and trunk associated OAM management. This makes it possible to configure Ethernet OAM
directly for network level objects, such as Ethernet trunks, VPLS VPNs, Ethernet and VLAN pseudowires and VLAN VPNs, instead of configuring it separately for each endpoint.

3.2.10 IP Address Management
The IP address management is a feature designed to prevent duplicate IP addresses in the network,
which could potentially interfere with the network configuration. When adding new IP addresses
or updating existing ones to the 8000 Intelligent Network Manager database, a check for findingduplicate IP addresses is done. If duplicates are found, a warning is displayed and then the operator
has two options: the warning can be overridden and the configuration can be continued, or the
configuration can be cancelled.

Faults are created for each network resource having the same IP address. In addition, the All IP
Addresses or IP Duplicates query can be executed in the Enhanced Reporting tool. The query
shows all the duplicates among the existing IP addresses.
Duplicate IP addresses are considered real if they can cause a conflict. There are no warnings or
faults for allowed duplicates. Examples of allowed duplicates include IP interfaces in different
MPLS VPNs, interface IP and node management IP in the same node, and Communication Server
IP and its domain adapter IPs.
The IP address management is supported for 8600 and 8800 IP interfaces, node IPs (management IP,
router ID IP, etc.) and Communication Server IPs. This feature is also supported in Node Managers,
VPN Provisioning, Autodiscovery Service and Macro Manager.
3.2.11 IP Address Pool Management
The IP Address Pool Management tool is designed to manage IP address pools and to allocate IP
addresses from the pools helping users to easily manage the IP configurations in the network. The IP
address pools can be added, modified and removed in the tool. IP addresses can be automatically
allocated from a certain IP address pool, or the next available IP address from an IP address pool can be assigned to an interface.
In addition, the All IPAddress Pools or IP Address Pool Usage query can be executed in the
Enhanced Reporting tool. The query shows information either on all IP address pools or on the
allocation of a certain IP address pool.
The IP address pool management is supported in Node Managers for 8600 IP and loopback
interfaces, and for 8800 L3, loopback and IRB interfaces.

3.2.12 Automated Deployment
The automated deployment is designed for deploying a large number of network elementsquickly with a minimum amount of manual effort. The automated deployment automates the
network element deployment by using the extensive preplanning support in 8000 Intelligent
Network Manager. Network element configurations are preplanned in the database with a set
of user-configurable templates. Newly deployed elements are detected automatically by 8000
Intelligent Network Manager and the configuration is pushed to the network element immediately
when the element is available in the network. It is possible to include IP VPN endpoint configuration
and even testing in the configuration process enabling the new network element to carry customer
traf fic within minutes after the physical installation and power on.
For the operator, the automated deployment functionality provides the following benefits, resulting
to lower operational expenses and fast time-to-market:
• Shortens the network and service rollout from days to minutes.
• Minimizes human errors and extra site visits.
• Enables ef ficient resource utilization, and reduces the training needs.
The deployment process takes place in four main phases:
• Planning (deployment planning and network planning)
• Physical installation
• Identification of the network element
• Deployment
The planning and physical installation requires manual work whereas the identification of thenetwork element and the deployment take place automatically. In the planning phase the operator
prepares 8000 Intelligent Network Manager for the deployment of the network elements (see the
figure below). The deployment planning is done for
• providing data for the Deployment Service (acting as a DHCP server) and 8000 Intelligent Net-
work Manager for identifying the network elements to be added to the network,
• preplanning the element and service configurations for the network elements to be added, and
• defining a deployment template containing the deployment steps, i.e. the operations to be run
once the network element is physically installed to the network.
8000 Intelligent Networ k Manager includes a set of wizards for assisting in the deployment
planning. The wizards are aligned for an easy creation of the basic configuration for adding thenetwork elements and endpoints to the IP VPN RAN for LTE. The configuration wizards and a
wizard for defining the deployment template are bundled into an application called Multi Node
Deployment Tool. The Multi Node Deployment Tool will pre-deploy the nodes, i.e. the preplanned
element and service configurations are created in the 8000 Intelligent Network Manager database.
Once the pre-deployment is done, it is possible to make further modifications to the preplanned
configuration in 8000 Intelligent Network Manager database with the 8000 Intelligent Network
Manager tools (e.g. Node Manager or VPN Provisioning).

Some layer 2 network planning is needed if the smart router autoconfiguration feature and the
DHCP relay agent information option 82 [RFC3046] are used for providing the initial management
IP address. The network design principle for supporting the location-based identification of the
option 82 is illustrated in the figure below. The network elements are connected to an Ethernet
switching network. The first Ethernet switch identifies the location of the network elements site
based on its ports. It translates the network element VLANs (e.g. VLAN ID 100) in each port to a
unique VLAN. At the DHCP relay agent, the Ethernet port number and the VLAN ID are mapped to
a circuit ID (e.g. “ge1/0.100”) and the routed ID of the DHCP relay is mapped to a remote ID. The
Deployment Service identifies the network element based on its location, i.e. circuit ID and remote
ID, and assigns an IP address allocated for the network element.

Fig. 63 Network Planning for Supporting DHCP Relay Agent Information Option 82
In the physical installation phase, the field technician connects the physical cables and powers thenetwork element on. If the smart router autoconfiguration feature is used in the process, the field
technician needs to connect an autoconfiguration dongle to the CLI console port before the network
element is powered on. This enables the network element autoconfiguration functionality where
the network element scans Ethernet interfaces and VLANs while searching for the DHCP server.
For further details of the smart router autoconfiguration, the use of DHCP relay agent information
option 82 and interface scanning, see Tellabs®
8600 Smart Routers IP Forwarding and Traf fic Management Con fi guration Guide.
The identification of the network element is based on the IP address given to the management
interface of the network element. The IP address can be automatically given by the Deployment
Service or it can be configured by some other means. When the Automated Deployment Network
Scanner (ADNS) finds the added network element, it tells the Automated Deployment Controller
(ADC) to start the deployment.
The added network element is configured in the deployment phase. If the DHCP protocol was used
for giving a (temporary) IP address, 8000 Intelligent Network Manager first configures a permanent
IP address for the management interface and removes the DHCP client configuration. Once the
management communication to the network element is ensured, 8000 Intelligent Network Manager
configures the element and services as planned in the planning phase. For accomplishing this, theAutomated Deployment Controller runs the operations defined in the deployment template (made in
the planning phase). The deployment operations may include, for example,
• downloading a certain element software version to the network element,
• copying the configuration from the database to the NE by raising the state of the node to installed
or In Use,
• raising the states of trunks and connecting RSVP-TE tunnels,
• adding new endpoints to IP VPNs.
The automated deployment is currently available for the 8602 Smart Router, 8605 Smart Router,
8609 Smart Router and 8611 Smart Router NEs.

3.3 Provisioning Packages
The TDM, ATM, Ethernet, FR/HDLC, IP VPN and Optical Provisioning Packages allow the operator
to choose what kind of services to configure in the network. There are three tools for provisioning
the services available in the 8000 Intelligent Network Manager: Router, VPN Provisioning
and VLAN Manager. The Router tool is used to provision TDM and optical circuits, the VPN
Provisioning tool is used to configure IP VPNs and VLAN VPNs, Ethernet, ATM, TDM, Frame
Relay and HDLC pseudowires, and the VLAN Manager tool is used to configure VLAN VPNs in
the 6300 and 8100 networks. Each provisioning package contains the following functionality:
• IP VPN Provisioning - The IP VPN Provisioning Package allows the user to provision IP VPNs
with the VPN Provisioning tool.
• Optical Provisioning - The Optical Provisioning Package allows the user to establish optical
(DWDM) and G.709 OTN connections in a network where the 7100 system is deployed.
• Ethernet Provisioning - The Ethernet Provisioning Package allows the user to configure Ethernet
pseudowires, VPLS VPNs and 7090/7100 based VLAN VPNs with the VPN Provisioning tool.
It also allows the user to provision VLAN VPNs in the 6300 and 8100 networks with the VLAN
Manager tool.
• ATM Provisioning - The ATM Provisioning Package allows the user to configure ATM pseu-dowires with the VPN Provisioning tool.
• TDM Provisioning - The TDM Provisioning Package allows the user to configure PDH and SDH
circuits with the Router tool and TDM pseudowires with the VPN Provisioning tool.
• FR/HDLC Provisioning - The FR/HDLC Provisioning Package allows the user to configure
Frame Relay and HDLC pseudowires with the VPN Provisioning tool.
In addition, there is a Tunnel Engineering tool to provision manually traf fic engineered LSPs inMPLS networks. The Tunnel Engineering tool is automatically included in each of the Provisioning
Packages, except for the Optical Provisioning Package.
Below, a more detailed description about each of the provisioning tools - Router, VPN Provisioning,VLAN Manager and Tunnel Engineering - is given.
3.3.1 Router
General
Router is a flexible 8000 Intelligent Network Manager tool where you can set up and manage circuits
through the 8000 system network. Router shows an overview of the network with the Navigator
Tree, List and Network View windows, views for different network objects (nodes, trunks, NTUs
and locations) and displays connection routes. You can zoom into nodes and interfaces to view and
set the communication parameters of the interfaces.
Connections are referred to as circuits. Circuits can be routed through the 6300, 7100, 8100 andmTera UTP network elements both automatically and manually. It is also possible to terminate
SDH and PDH circuits in the 8600 and 8800 network elements. The circuits can be completely or
partially connected and disconnected. It is also possible to create planned circuits without a physical
network. In this way the connections can be built in advance using planned interfaces and trunks.
The circuit only has to be connected to be operational when the physical network is available.

3 8000 Intelligent Network Manager Application Packages
Currently optical, ODUk, SDH, SONET, PDH, ATM and Frame Relay circuits are supported.
Circuits are also used to route virtual VC-4/2/12, VLAN, 2M, 1/1, ATM, Frame Relay and STM-64
trunks through the high-order network.
By enabling the Multi-Layer Routing feature, you can semi-automatically create VC-12 trunks over
the SDH 4/1 layer with Trunk Wizard when routing PDH 1/0 circuits.
With 2M Cascaded circuits, you can use the 4/1, 1/1 and 1/0 layers in the same circuit without
having to create virtual trunks when switching between layers.
If you have 6300 ETEX units in your network, you can use their VC groups in Diverse SDH circuits.
With the diverse circuit you can route each child VC interface of a VC group separately or together
with a selection of any other child VC interface of the VC group. You can also add or remove VC
child interfaces later to / from the VC group and route / unroute them later without disturbing the
traf fic. This can be used with LCAS for network protection and dynamic capacity change.
Circuit Components
A circuit is identified by a unique ID and name. The necessary circuit parameters, such as capacity,
customer and signaling, must be specified at the initial state when creating the circuit. The capacity
can be in the range of 8 kbps – 10 Gbps. The basic circuit consists of two endpoints (NTUs
or interfaces) and a route.
A route is created by allocating, manually or automatically, capacity from the trunks. Manual
routing is done by simply selecting (double-clicking on) the trunks with enough capacity (colored
green/dark green). The automatic routing uses a shortest path algorithm to find the optimal route by
calculating a set of weighted criteria (length, cost, delay and occupation).
Reserve backup routes for PDH 1/0 circuits can be pre-routed by Router or dynamically routed by
Recovery Management. They are used by Recovery Management to back up the primary route
when necessary.
In a partitioned network, the network is divided into regions into two levels, backbone and access.
Backbone level trunks are high-capacity trunks carrying only inter-regional data. Access level
trunks are mainly used for carrying data within the region. To keep this structural two-level network
well differentiated, you need to control the way you route. In short, regional routes use access
level trunks, and inter-regional routes mainly use backbone level trunks. For more information on
partitioning, refer to 3.11 Partitioned Package.
A complex circuit with several endpoints consists of several subcircuits to help manage the circuit.
In this way the circuit topology can be changed even while the original circuit is still active. The
subcircuits can, naturally, be separately connected and disconnected.
Circuit Topologies
The types of circuits supported are point-to-point (pp), point-to-multipoint (pmp) and broadcast (bc).
The point-to-point type of circuit, which is the most commonly used, is bi-directional and consists
of two end interfaces and a route, see Fig. 6. Interfaces for test purposes can also be added, butthey are used only in the Circuit Loop Test tool. When transporting a PCM signal, it is possible
to compress the signal to an ADPCM signal in order to save trunk capacity in the network. The
compression can be from 64 kbps to 32, 24, 16 or 8 kbps.

A special Circuit Swap feature can be used for the swap type of point-to-point circuits. The idea is
to allow the replacing of a circuit endpoint by another when, for some reason, the primary endpoint
is damaged. By convenience, several swap circuits can use the same swap point in order to allow
replacement of endpoints for several circuits in a single step.
The broadcast type of circuit is uni-directional and consists of one master and any number of slave
interfaces, branch nodes, subcircuits and routes.
The point-to-multipoint type is similar to the broadcast type of circuit, but the data flow is
bi-directional. Additionally, branch nodes have special Point-to-Multipoint (PMP) Servers that are
used to control data flow in the slave-master direction.
Network Optimization Tools
With the Reroute Circuits tool, you can select a set of PDH or SDH circuits and select alternative
endpoints and automatically route alternative paths with desired routing templates. Then the
connections can be swapped, and the unused routes deleted. This is useful when new nodes/trunkshave been installed or when the network topology is changing due to growth.
For the PDH, SDH and ATM circuits you can also route, unroute, connect and disconnect the
original paths.
The routing template basically controls what trunks to use or not to use. Weights can also be set
to optimize the route for cost, length, delay, occupation or a combination of these. The routing
templates are stored in the database, and special privileges are required to edit them. It is also
possible to keep a local routing template that is not stored in the database.
3.3.2 VPN Provisioning
The VPN Provisioning package provides tools for creating, modifying and deleting different kinds
of MPLS VPN services, in other words, pseudowires, VPLS VPNs and BGP/MPLS IP VPNs. In
addition, provider bridging based VLAN VPN services for the 7100 packet subsystems as well as
7090 and 8800 network elements are supported. Additionally, G.8032 rings are supported for the
7100 packet subsystems. These services are collectively referred to as VPN services in the text
below. The VPN Provisioning tool provides a high-level user interface for establishing any type
of these VPN services. Interfaces in which VPN endpoints are created can be chosen from a
tree view, where interfaces or entire nodes bound to customer sites are displayed below customer
and site information.
The main window of the VPN provisioning tool is shown in the figure below.

Fig. 64 Main Window of VPN Provisioning Tool
The VPN Provisioning tool supports ten different VPNs: Ethernet Pseudowire Mesh, ATM
Pseudowire Mesh, TDM Pseudowire Mesh, FR Pseudowire Mesh, HDLC Pseudowire Mesh, VPLS
VPN, VLAN VPN, G.8032 ring, BGP/MPLS VPN and Default Routing Access.
A Pseudowire Mesh VPN has a point-to-point topology with two endpoints connected with a
pseudowire. You may create several point-to-point pseudowires under the same VPN, therefore
creating a pseudowire mesh. For the Ethernet pseudowires, the two endpoints will either be in
Ethernet ports or VLAN/S-VLAN sub-interfaces. For ATM pseudowires, the endpoints will either be ATM VP or VC sub-interfaces. For TDM pseudowires, the endpoints will be either E1/T1
interfaces or nx64 kbps interfaces configured on top of the E1/T1 interfaces. The E1/T1 interfacemay be native E1/T1 interfaces or E1/T1 streams aggregated onto SDH/SONET channelized
interfaces. For Frame Relay pseudowires, the endpoints will be Frame Relay PVCs. For HLDC
pseudowires, the endpoints will be HDLC interfaces. Also TDM, ATM, Ethernet, Frame Relay and
HDLC cross-connections (locally connected pseudowires) are supported.
For pseudowires, two different topologies are supported: single-segment and multi-segment. These
differ in how the pseudowire is carried in the packet-based transport network. A single-segment
pseudowire is carried end-to-end by one packet network tunnel, whereas a multi-segment
pseudowire consists of many segments, each carried by a separate tunnel, which are switched inintermediate nodes. Multi-segment pseudowires provide a more flexible and scalable mechanism for
managing pseudowires, supporting e.g. aggregation of multiple pseudowires into the same tunnel in
hub points and interconnectivity between different packet network domains.

For protecting pseudowire-based services, pseudowire redundancy (as per [draft-ietf-pwe3-
redundancy-03] and [draft-ietf-pwe3-redundancy-bit-03]) is supported. The pseudowire redundancy
mechanism supports multiple protection schemes, e.g. protecting a multi-segment pseudowire
end-to-end by configuring multiple redundant paths for the PW, or providing multi-homing based
service protection when a part of the service is implemented with pseudowires. The pseudowire
redundancy for the end-to-end protection is presented below.
Fig. 66 Pseudowire Redundancy
VPLS VPNs may have multiple endpoints. Each endpoint is connected, either locally or via a
pseudowire, to an Ethernet Virtual Switching Instance (VSI). The VSIs in different nodes are then
interconnected with MPLS pseudowires either in a full mesh fashion or, when using hierarchicalVPLS (H-VPLS), in a hierarchy, to allow any-to-any connectivity between the endpoints. Together,
the switches form a Virtual Private LAN Service instance, emulating a single LAN to the end user.
An example of an H-VPLS VPN is presented below.

Fig. 67 H-VPLS VPN
A VLAN VPN is a static S-VLAN based service which may have multiple endpoints. VLAN trunks
and G.8032 rings are used for routing the service in such way that there are no loops in the route (a
G.8032 will not form a loop since one of the trunks is always open). The endpoints of the service
may e.g. terminate a single/multiple C-VLAN(s) in a Customer Edge Port (CEP), all C-VLANs of
a port-based Customer Network Port (CNPP) or an S-VLAN of an S-tagged Customer Network
Port (CNPS). This service can also be a protected point-to-point service, but in such case the route
consists of an RVT trunk. In addition, a VLAN VPN service can be terminated to a VPLS/PW
VPN service in an 8800 network element. For a protected point-to-point service using the openRVT solution in the 7090 network, the termination towards the VPLS service in the 8800 network
provides dual homing i.e. there are two termination endpoints towards the VPLS service.
There are two different types of Resilient VLAN Tunnels (RVT), i.e. XC-RVT and VB-RVT, and
they are used for protecting point-to-point VLAN services. An RVT has a working and a protection
path, which are routed using VLAN trunks and G.8032 rings, but the path must always start/end
using a VLAN trunk. The XC-RVT is used in the 7100 nodes for connecting/tunneling one or more
point-to-point VLAN services at the endpoint nodes of the RVT whereas the VB-RVT is used in the
7090 nodes for bridging a single point-to-point VLAN service to the RVT. The RVT has a protection
group at its endpoints for switching between the working and protection paths depending on when
a failure occurs in the active path.
A G.8032 ring consists of a set of VLAN trunks making up a ring. The VLAN VPN services can
be routed through the G.8032 rings, and they will be protected by the ring protection mechanism
even if a single trunk in the ring fails. The G.8032 ring provides an alternative and faster protection
mechanism to the spanning tree protocol for building multipoint VLAN services. The protection
mechanism can also be used as an alternative to an RVT trunk if the endpoints of the point-to-point
service are located at the nodes of the ring. This solution is more scalable since the protection
groups used in the nodes of the ring are shared by many services. One of the trunks in the G.8032
ring is defined as a Ring Protection Link (RPL) trunk. As the VLAN traf fic in the ring should
not make any closed loops, the RPL trunk is open if there are no errors in the ring, and it will be
closed when there is an error in another trunk of the ring. A G.8032 ring can also have one or more
sub-rings. The sub-ring is connected to its parent with two nodes (dual homing for avoiding a
single point of failure) called interconnection nodes. The sub-ring in a trunk has an own RPL trunk
functioning according to the same principle as in the main/parent ring.

3 8000 Intelligent Network Manager Application Packages
BGP/MPLS VPNs may have multiple endpoints. Three different topology types are supported for
these kind of VPNs
1. Full mesh: Traf fi
c may be sent from any endpoint to any other endpoint through the VPN.2. Central services hub-and-spoke: Traf fic may be sent from a single hub endpoint to any of the
spoke endpoints or from any of the spoke endpoints to the hub endpoint. However, the spoke
endpoints may not communicate with each other through the VPN.
3. Full-featured hub-and-spoke: Also referred to as firewall hub-and-spoke based on one typi-
cal application. In this VPN topology the spoke endpoints can communicate with each other
through a customer router that lies behind the hub endpoint. Actually there are two endpoints
for hub here, one for incoming traf fic from the spokes towards the hub and another for outgoing
traf fic from the hub towards the spokes.
In the Default Routing Access type of service, the interfaces associated with the service do
not belong to any VPN. The IP traf fic originating from the interfaces will be routed using the
default routing table, thus interfaces belonging to different Default Routing Access instances may
actually communicate with each other. The Default Routing Access instances can be thought of as administrative instances for the service, used for documenting the interfaces where broadband
services have been configured.
In addition to these topologies available for customer VPNs carrying payload data, VPN
provisioning also supports a single management VPN (one per network) enabling central
management of the non VPN-aware CE routers on the customer premises. The topology of the
management VPN is like that of the central services hub-and-spoke VPN, with the exception that the
management VPN may have more than one hub site.
The work flow for establishing IP VPN services is basically the same as for pseudowires. However,
for the IP VPNs there are some additional steps related to classifying and policing the traf fic and
configuring routing options towards the customer networks.

Pseudowire Wizard
The Pseudowire Wizard is a very handy tool when creating a large number of pseudowires in the
network. The wizard allows you to select a group of source and destination interfaces from the
network and it will then create the needed pseudowires between the selected interfaces. If required,the wizard can connect the pseudowires during the same operation.

Discovering Pseudowires and IP VPNs
It is possible to discover pseudowires and IP VPNs that have been configured in the 8600 network
elements directly through the command line interface. The discovery functionality has been
implemented for those who want to roll out the network quickly with pre-generated CLI scripts.
After the roll out phase, the pseudowires and IP VPNs can be uploaded to the 8000 Intelligent
Network Manager and managed centrally from the network management system with the discovery
functionality.
Reparenting Pseudowires
VPN Provisioning also contains Pseudowire Editor that is convenient to use for re-parenting
pseudowires. You can select a group of interfaces used for pseudowires and select Move
Endpoints from the pop-up menu. Then select the destination interfaces where you want to move
the pseudowires and click start. All pseudowires in Pseudowire Editor will be moved to the
new destination interfaces. Pseudowire Editor can also be used to edit basic parameters of the
pseudowires.

7100 Service Endpoint Mapping Wizard and 7100 VCAT Diverse Circuit Wizard
Creating an end-to-end packet-over-SDH/SONET (PoS) circuit using the 7100 SSM-D/X cards
requires many steps, and critical steps in the procedure may be overlooked leading to suboptimal
performance. There are two wizards in 8000 Intelligent Network Manager aimed at helping to
make such procedures easier and more effective: 7100 Service Endpoint Mapping Wizard and
7100 VCAT Diverse Circuit Wizard.
The 7100 Service Endpoint Mapping Wizard is a tool used for setting the parameters and optionally
creating all the required entities, including the Ethernet ports, link aggregation groups and Ethernet
virtual connections associated with an SDH/SONET circuit that has already been created with
the Router tool.
The 7100 VCAT Diverse Circuit Wizard encompasses all the functionality found in the 7100 ServiceEndpoint Mapping Wizard, but additionally it can be used for creating an entirely new SDH/SONET
diverse circuit used for carrying the traf fic across the network.

3.3.3 Tunnel Engineering
The Tunnel Engineering tool can be used for creating traf fic engineered LSPs either when provisioning an MPLS VPN or as an entirely separate action. It can also be used for setting explicit
routes for traf fic engineered LSPs and for viewing routes of existing LSPs in the network.
The Tunnel Engineering tool supports the following tunnel types:
• RSVP-TE tunnels. The RSVP tunnels are MPLS-switched tunnels signaled with the RSVP-TE
protocol.
• MPLS-TP tunnels. The MPLS-TP (MPLS Transport Profile) tunnels are MPLS-switched tunnels
configured statically, node by node, in the network by 8000 Intelligent Network Manager.
• IP tunnels. The IP tunnels are used for transporting pseudowires over an IP infrastructure when
MPLS is not available.
• Static LSPs. The static LSPs are statically configured single-hop MPLS tunnels.
The main window of the Tunnel Engineering tool is shown in the figure below.

Fig. 75 Main Window of Tunnel Engineering Tool
For the RSVP-TE and MPLS-TP tunnels, the Tunnel Engineering tool supports automatic,
semi-automatic and manual routing of tunnels. In the automatic routing, the tunnel is automatically
routed between the endpoint nodes. In case of the RSVP-TE tunnels, the route is calculated by the
source node using the CSPF (Constrained Shortest Path First) algorithm, whereas in case of the
MPLS-TP tunnels, the route is calculated by 8000 Intelligent Network Manager using its internalSPF (Shortest Path First) algorithm. In the semi-automatic and manual routing, the user defines
the hops (strict and/or loose) that are to be used as part of the route. In the manual routing all hops
are given along the path, whereas in the semi-automatic routing only some of the hops are given
and the node (in case of RSVP-TE) or 8000 Intelligent Network Manager (in case of MPLS-TP)
calculates the rest of the route. Additionally, it is possible to use bandwidth reservations for the
tunnels. A bandwidth value can be defined for the tunnel, which is to be reserved on the trunks alongthe path of the tunnel. For the RSVP-TE tunnels, bandwidth reservations are maintained by the
network elements, whereas for the MPLS-TP tunnels, the bandwidth reservation is maintained in the
8000 Intelligent Network Manager database.

For the MPLS-based tunnels (RSVP-TE and MPLS-TP), both E-LSP and L-LSP tunnels are
supported. The difference between these is essentially that while a single E-LSPs can carry traf fic
belonging to multiple service classes, a single L-LSP only carries traf fic belonging to a single
service class.
Tunnel protection is supported for the RSVP-TE and MPLS-TP tunnels. For the RSVP-TE tunnels,
RSVP-TE 1:1 Path Protection and RSVP-TE Fast Reroute Protection (RFC 4090) are supported.
For the MPLS-TP tunnels, MPLS-TP Linear Protection (RFC 6378) is supported.
Discovering Tunnels
It is possible to discover RSVP-TE and MPLS-TP tunnels that have been configured in the 8600 and
8800 network elements directly through the command line interface. The discovery functionality
has been implemented for those who want to roll out the network quickly with pre-generated CLI
scripts. After the rollout phase, the tunnels can be uploaded to the 8000 Intelligent Network
Manager and centrally managed from the network management system.
Discovering other tunnel types is currently not supported.
3.3.4 VLAN Manager
VLAN Manager is an optional tool for 8000 Intelligent Network Manager. It is used for graphical
and user friendly provisioning of VLAN connections, i.e. VLAN VPNs.
VLAN Manager is a part of Ethernet switched solution (ESS) concept. The concept makes it
possible to use an existing 6300/8100 network as a core network for layer 2 Ethernet services.
VLAN Manager is used only for VLAN VPN provisioning. Other management tasks suchas creating layer 1 connections are performed with other 8000 Intelligent Network Manager
applications, which enable seamless integration into TDM provisioning and eliminate the need of
redundant configuration work.
VLAN trunks, i.e. layer 1 connections between Ethernet/VLAN switching network elements, are
created in the same way as the other trunk types in 8000 Intelligent Network Manager by using
Network Editor. VLAN Manager considers VLAN trunks as TDM capacity reserved for VLAN
Manager use and uses the VLAN trunk information stored into the 8000 Intelligent Network
Manager database to calculate optimal routes for VLAN VPNs.
The VLAN Domain Configuration tool has also been integrated into Network Editor. The tool
automates the configuration of VLAN domain wide (e.g. QoS) parameters into the Ethernet/VLAN
switching network elements. VLAN domains are separate Ethernet/VLAN network instances, i.e.sets of Ethernet/VLAN switching elements and VLAN trunks that connect them.
3.4 Testing Package
3.4.1 Overview
The Testing Package contains the Packet Loop Test and Circuit Loop Test tools for troubleshootingcircuits, pseudowires, VLAN, VPLS, and IP VPNs services. The Circuit Loop Test tool can be used
for services in TDM-based networks whereas the Packet Loop Test tool has been designed for
services in MPLS and Ethernet based networks.

3.4.2 Packet Loop Test
Overview
Packet Loop Testing is a testing tool for detecting and localizing problems in packet networks and
verifying services, created by 8000 Intelligent Network Manager VPN Provisioning tool. It contains
a collection of test packages including different test items. The network can be tested after setting up
a new node or fixing a trunk fault or before creating a new service. With IP VPN and PW tests the
user can ensure that the IP VPN and PW are working correctly and fulfilling the QoS requirements
configured before taking the service into use.
The tests can be executed manually or they can be scheduled for automatic execution in the background. The tests running in the background could be used to give the operator a daily view of
the network and the services.
The results of the tests can be stored in the database for further analysis.
Test Packages
Packet Loop Testing contains the following test packages and test items:
Management Communication Test Package contains functionality for testing the communication
between 8000 Intelligent Network Manager and nodes. This package includes the following tests:
• Node Management Connectivity Test pings nodes to check the IP-level connectivity between
the Communication Server and the nodes.
• Node Management Traceroute Test detects the route along the Communication Server and thenodes. It can be useful when investigating management connectivity problems between the 8000
Intelligent Network Manager and a node.
• Trunk Management Connectivity Test test the IP-level connectivity between the Communica-
tion Server and one or both end nodes of a specific trunk in the network.
• IP VPN Management Connectivity Test pings all endpoint nodes of the IP VPN to check the
IP-level connectivity between the Communication Server and the nodes. Note that the loopback
interface of the node is tested instead of the real IP VPN endpoint interface.
• PW Management Connectivity Test pings all endpoint nodes of the pseudowire to check the
IP-level connectivity between the Communication Server and the nodes. Note that the loopback
interface of the node is tested instead of the real PW endpoint interface.
• TE Tunnel Management Connectivity Test pings the endpoint nodes of the tunnel to check theIP-level connectivity between the Communication Server and the nodes. Note that the loopback
interface of the node is tested instead of the real tunnel endpoint interface.

• Node Connectivity Test pings nodes to check the IP or LSP level connectivity between two
nodes. The LSP level connectivity test requires MPLS support from the nodes – at the minimum.
• Node Traceroute Test traces the path between two nodes. It can be useful when investigating
node connectivity problems in the network.
• The Node Quality Test Sub-package can be used for testing the quality of the connectivity be-
tween two nodes.
• Node Throughput Test is an intrusive test for determining the maximum bandwidth avail-
able between two nodes without having the traf fic discarded. This test should be used with
care as it will affect live traf fic in the network and is usually only used in the initial deploy-
ment phases of the network. This test is supported in the 8600 node hardware and therefore
throughput between two nodes can be tested up to the line-speed of the interfaces in the
node. Packet distribution, send interval and QoS distribution can conveniently be selected
using predefined templates. It is also possible for the user to define his own distribution
values.
• Node Round-trip Delay Test is used for testing the round-trip delay of packets sent between
two nodes. This test is supported in the 8600 node hardware and therefore micro-second
accuracy can be obtained for the test results.
• Node One-way Delay Test can be used for testing the delay of packets sent between two
nodes. It needs accurate time synchronization between the nodes e.g. by using NTP.
• Node One-way Delay Variation Test can be used for testing the one-way delay variation
between two nodes. This test is supported in the 8600 node hardware and therefore micro-
second accuracy can be obtained for the test results.
• Node One-way Packet Loss Test can be used for testing the packet loss for packets sent
between two nodes. Packet distribution, send interval and QoS distribution can be defined
using predefined templates, or the user can define them manually.

Trunk Test Package contains functionality for testing basic router network communication between
trunk end nodes in a basic router network. These tests can be run unidirectionally or bidirectionally.
• Trunk Connectivity Test pings trunk end nodes to check the IP-level connectivity between those
two end nodes.
IP VPN Test Package contains functionality for executing tests on individual VPNs. The IP VPN
tests are a combination of different tests that are organized so that the operator needs to execute
only a few tests manually.
• IP VPN Connectivity Test gives the operator the ability to test the connectivity automatically
between all endpoint interfaces of an IP VPN.
• IP VPN Traceroute Test allows the operator to discover the routes between all endpoint inter-
faces of an IP VPN.
• IP VPN Quality Test Sub-Package enables the operator to test the quality of transmission be-
tween each site in an IP VPN. These tests are supported in the 8600 node hardware, therefore,
both elements must be 8600 nodes.
• IP VPN Throughput Test is an intrusive test for determining the maximum bandwidth that
a certain IP VPN has between the endpoints in the IP VPN. This test will affect the IP VPN
traf fic and can also affect other traf fic in the network, so it should be used carefully. This
test is typically used when provisioning a new IP VPN to make sure that the IP VPN can
carry the traf fic provisioned for the user without discarding traf fic. This test is supported in
the node hardware, which means that traf fic can be generated up to the interface line-speeds.
Packet distribution, send interval and QoS distribution can conveniently be selected using
predefined templates. It is also possible for the user to define his own distribution values.
• IP VPN Round-trip Delay Test is used to measure the round-trip delay of packets being
sent between the endpoints in the IP VPN. This test is supported in the node hardware, and
therefore micro-second accuracy can be obtained.
• IP VPN One-way Delay Variation Test is used to test the one-way delay variation of test
packets sent between the endpoints in an IP VPN. This test is supported in the node hard-
ware, and therefore micro-second accuracy can be obtained.
• IP VPN One-way Packet Loss Test can be used for testing the packet loss for packets sent
between endpoints in an IP VPN. Packet distribution, send interval and QoS distribution can
be defined using predefined templates, or the user can define them manually.

• PW Connectivity Test can test the connectivity inband and end-to-end for a pseudowire having
the VCCV control channel enabled using the VCCV ping for all PW types. This is a powerful
test for verifying the consistency between the control plane and forwarding plane for the tested
PW. In addition, the ATM ping is supported for ATM based PWs, and Ethernet Ping for Ethernet
PWs. Maintenance endpoints (MEPs) need to be created at the ends of an Ethernet PW in order to test it. It is also possible to select an ICMP ping based test between the end nodes of the PW
e.g. when VCCV is not enabled for a PW or there are no MEPs at the ends of an Ethernet PW.
• PW Traceroute Test traces the path inband and end-to-end for a pseudowire having the VCCV
control channel enabled using the VCCV traceroute for all PW types. This is a powerful test
for verifying the consistency between the control plane and forwarding plane for multi-segment
PWs. It is also possible to select an ICMP traceroute based test between the end nodes of the PW
e.g. when VCCV is not enabled for a PW.
• The PW End Node Quality Test Sub-package can be used for testing the quality of the connec-
tivity between the end nodes of a pseudowire.
• PW End Node Throughput Test is an intrusive test for determining the maximum band-
width available between the end nodes of a pseudowire without having the traf fic discarded.This test should be used with care as it will affect live traf fic in the network and is usu-
ally only used in the initial deployment phases of the network. This test is supported in the
8600 node hardware and therefore throughput between two nodes can be tested up to the
line-speed of the interfaces in the node. Packet distribution, send interval and QoS distribu-
tion can conveniently be selected using predefined templates. It is also possible for the user
to define his own distribution values.
• PW End Node One-way Delay Variation Test can be used for testing the one-way delay
variation between the end nodes of a pseudowire. This test is supported in the 8600 node
hardware and therefore micro-second accuracy can be obtained for the test results.
• PW End Node One-way Packet Loss Test can be used fortesting the packet loss for packets
sent between the end nodes of a pseudowire. Packet distribution, send interval and QoS
distribution can be defined using predefined templates, or the user can define them manually.

• TE Tunnel Connectivity Test can test the connectivity inband and end-to-end for an RSVP TE
tunnel using the LSP ping. This is a powerful test for verifying the consistency between the
control plane and forwarding plane for the tested tunnel. It is also possible to select an ICMP
ping based test between the end nodes of the tunnel e.g. when troubleshooting situations where
an LSP ping based test gives a connectivity error as a result.
• TE Tunnel Traceroute Test traces the path inband and end-to-end for an RSVP TE tunnel using
the LSP traceroute. This is a powerful test for verifying the consistency between the control
plane and forwarding plane for the tested tunnel. It is also possible to select an ICMP traceroute
based test between the end nodes of the tunnel e.g. when troubleshooting situations where an
LSP traceroute based test fails to trace the complete path.
• The TE Tunnel Quality Test Sub-package can be used for testing the quality between the end
nodes of a tunnel.
• TE Tunnel Throughput Test is an intrusive test for determining the maximum bandwidth

be run unidirectionally or bidirectionally. The maintenance domain, maintenance association,
maintenance endpoints and maintenance intermediate points associated with the service need to

• VLAN Connectivity Test checks the connectivity between the service endpoints using an
802.1ag based loopback message between the source and destination MEPs associated with the
service.
• VLAN Traceroute Test traces the path checks between the service endpoints using an 802.1ag based link trace message between the source and destination MEPs associated with the service.
Intermediate MIPs found in the path are reported. This can be useful when investigating connec-
tivity problems in a network for the VLAN VPN service.
• The VLAN Quality Test Sub-package can be used for testing the quality between service end-
points located at 7090-05 CE, 7090-07 CE, 7090-15 CEM or 7090-25 CE (only the 82.7325A
switch module) nodes of a VLAN VPN service according to RFC2544. The endpoints to be
tested need to have MEPs. The test will be executed using multiple frame sizes, starting the test
from the smallest frame size towards the largest testable frame size in each iteration. Results will
be given separately for each frame size used in the test. The frame sizes to be used in the test can
be selected by the user, or the default frame sizes specified in RFC2544 can be used.
These tests are intrusive and can therefore be service-affecting when using high bit rates inthe tests. Thus, pay special attention when selecting the bit rate to be used in the test.
• The VLAN Throughput Test is used for determining for each testable frame size if the
frames using the given bit rate can be passed between the VLAN endpoints without losing
frames. When there are lost frames using the given bit rate, the test algorithm in the node
will iterate in order to find a bit rate at which frames are not lost in the test.
• The VLAN Round-trip Delay Test is for determining the latency for each testable frame
size using the given bit rate when frames can be passed between the VLAN endpoints with-
out losing frames. When there are lost frames using the given bit rate, the test algorithm in
the node will iterate in order to find a bit rate at which frames are not lost and measure the
latency of such frames.
• The VLAN Frame Loss Test is used for determining for each testable frame size the frame
loss rate using the given bit rate between the VLAN endpoints. If frames are lost using the
given bit rate, the frame loss rate will be measured using 90%, 80%, … of the given bit rate
until no frames are lost.
• The VLAN Burst Test is used for determining the maximum number of frames that can be
sent in a burst so that received frames are not lost using the given bit rate for frames sent
between the VLAN endpoints.
The following figures show examples of the windows in the VLAN Quality Test Sub-package.

Background Test Manager
The Background Test Manager contains functionality for defining and scheduling tests that areexecuted in the background. If the tests are run by the 8600 nodes, these are basically performance
tests, that is, they produce performance data to be used by, e.g., Integrated Performance Management
tools. Note that not all tests can be scheduled to run in the background. The test can be scheduled to
run once or on a minute, hourly, daily, weekly or yearly basis in a specified time interval.
The basic operations for managing background tests are the following:
• Adding a new test schedule
• Viewing the status of background tests
• Suspending a running background test
• Resuming a suspended background test• Deleting an existing background test schedule
• Modifying an existing background test configuration
• Viewing the result of the background tests
The following figure shows an example of the GUI of the Background Test Manager window.

SLA Monitoring
The Background Test Manager can be used for SLA monitoring of services configured on the
8600 nodes. The node, IP VPN and PW throughput, one-way delay variation, round-trip delayand packet loss tests can be scheduled in the background and a threshold can be assigned to the
tests. If the threshold is exceeded, the background test manager will insert a fault in the database
notifying the user of an SLA violation.
3.4.3 Circuit Loop Test
The Circuit Loop Test is a testing tool for detecting and localizing problems in those circuits created
by 8000 Intelligent Network Manager. It can help to qualify the circuits or transmission media by
giving detailed performance results. Several features allow the user to test different sections of a
circuit. Different test patterns and loops can be used. The control signal operation can be tested
separately, and a break in a circuit can be easily detected.
The Circuit Loop Test facility supports three categories of circuits: PDH 1/0 and SDH paths and
ATM Virtual Paths. For the PDH 1/0 circuits the Circuit Loop Test window allows activating
test pattern generation and reception in order to retrieve detailed results including error rate, failure
and performance statistics. For the ATM virtual paths there are two tests: loop back test for data
transmission testing and continuity check test for permanent continuity monitoring. With the
Circuit Loop Test window it is also possible to define ATM virtual path segment endpoints required
for loop back and continuity check. The SDH paths have their own test window, which allows
access to several 8000 Intelligent Network Manager tools and can also activate a cross-connection
loop on the path.

General Test Properties for PDH 1/0 Circuits
For the PDH 1/0 circuits, the Circuit Loop Test tool supports testing of point-to-point, compressedpoint-to-point, swap point-to-point, broadcast and point-to-multipoint circuit types. All types,
except for compressed point-to-point circuits, can be tested at the endpoint level. Compressed
point-to-point circuits must be tested at the subcircuit level because they are not bit-transparent
from end to end.
All different types of point-to-point circuits can be tested either uni-directionally or bi-directionally.
A test is defined by selecting a subset of available resources between the endpoints. If a swap
point-to-point circuit is tested, one of the possible endpoint pairs must be chosen first.
When testing a broadcast circuit, the master endpoint and at least one of the slave endpoints must
be selected. It is normally possible to select any number - from one up to all - slave endpoints for
testing. However, the lack of common test resources can sometimes be a restriction.
Point-to-multipoint circuits are tested uni-directionally in the same way as the broadcast circuits.
The point-to-multipoint circuits can also be tested bi-directionally. In that case the master endpoint
and only one of the slave endpoints can be selected for testing.
A so-called intermediate node can be selected along the route of a circuit. The intermediate node
provides additional resources for testing.
It is also possible to test the predefined backup routes of point-to-point circuits. At the beginning,
the primary route is disconnected and the predefined backup route is connected. After that the
circuit can be tested in a normal way.
Test endpoints are additional interfaces that can be used for monitoring the data flow through the
actual circuit. This is a useful way to perform long-term monitoring tests without disturbing thecircuit. This feature is available for point-to-point circuits only.
Available Resources
There are three different resource types for testing purposes. Test resources are objects that can
transmit and receive data and control signals. Loops are used for looping the received signal
back to the original source. Redirections are used for directing the signal to test an endpoint for
monitoring purposes.

• Test resources are used to generate appropriate test data patterns or control signals. The circuit-
specific test resource is, for example, in an interface that is reserved by the circuit. The node
common test resource can also be used in access nodes or intermediate nodes. If the intermediate
node is a branch node in a point-to-multipoint circuit, there are two additional test resources in
the PMP Server units (VCM or GCH-A). The node common test resource is located in a controlunit (e.g. SCU and SCU-H). In addition, there is a test resource in every VCM and GCH-A
interface. There are test resources also in NTUs (for further information, refer to the appropriate
NTU manual or booklet).
• Loops are used for looping the incoming signal back to the original source. There are three
different places where a loop can be activated or created:
X-Connection The signal is looped back using a cross-connection
command to the given port of an endpoint interface
or trunk.
Loop in Interface A loop that is activated by a management command
in the given endpoint interface. This kind of aloop can be activated in the CAE, CCO, CCS,
GCH-A, GMH, IUM, ISD-LT, ISD-NT and VCM
interfaces.
Loop in NTU A loop that is activated by a management command
in the given Network Terminating Unit (NTU).
There are NTU loops in all NTU types.
• Redirections are located in a special kind of intermediate nodes called Test Branch Nodes. The
test branch node is the place where the incoming signal can be directed to test an endpoint. There
are two types of redirections. Listening of an endpoint means that you direct the signal to the
test endpoint by making a uni-directional connection from the endpoint to the test endpoint. The
normal operation of a circuit is not disturbed in any way. The other way is to replace one of theendpoints by a test endpoint. The original connection is removed and a bi-directional connection
is made from the other endpoint to the test endpoint. It is possible to create only one redirection
to one endpoint. Redirections to both endpoints can be activated at the same time.
Test Types
Testing of circuits can be separated into two categories. An internal test is performed by using one
or more test resources for transmit/receive purposes. In an external test neither a test pattern nor a
control signal is generated by Circuit Loop Test. External equipment is used for performing the test.
• Internal Test includes two different sets of tests. The first one is often referred to as a Control
test which is performed on the circuit control signals (105-109, 108-107, 105-106) by driving the
circuitry directly. The second one is simply called a Test. This means that the data path is tested
using different test patterns.
• External Test can be activated by making a loop-back or by using redirections. The external
equipment can, for example, transmit or receive data like a test resource. Monitoring the incom-
ing or passing signal is another example.
Both asynchronous and synchronous circuits can be tested.

Test Results
The Circuit Loop Test facilities allow the user to activate test pattern generation and reception of PDH 1/0 circuits in order to retrieve detailed results, including error rate, failure and performance
statistics. In the case of ATM virtual paths, the test results consist of the count of test cells looped
back or the presence of the loss of continuity fault in Fault Management, depending on the ATM test
type. Circuit Loop Test collects no results for SDH cross-connection loops. The current test status is
displayed while a test is active on a workstation. In addition, all types of active tests (PDH 1/0,
ATM, and SDH) can be saved on the test catalogue in the database. The workstation can even be
switched off while the testing remains active in the 8100 system network. In these cases the tests
are called background tests. The background tests can be accessed again or terminated at any time
by starting Circuit Loop Test for them again.
The test results are presented as bit error and G.821 counters, signal interruption counters, cell
counters or faults, depending on the test. When external test equipment is used, no test results are
available.
Characteristics of SDH Path Loop Test
The SDH Testing tool has two modes, intrusive and non-intrusive. In the non-intrusive mode one
can view faults, performance and trail trace from accessible VC objects. The intrusive mode adds a
capability to set cross-connection loops; add Supervisory Unequipped VC objects and access the
tool for SNC switch manipulation.
The window shows the whole SDH circuit at the same time. All nodes, trunks, internal connections
and VC objects are drawn. Endpoint information is shown for circuit endpoints. Accessible VCobjects related to the circuit are drawn as gray triangles. Typically, there are terminating VC objects
at circuit endpoints and possibly monitoring VC objects at SNC/N branch points.
Non-Intrusive Testing
Non-intrusive testing does not disturb circuit traf fic, unless one changes trail trace. The tools include:
• Trail Trace tool starts the Trail Trace Tool. It can be started for a single VC object or a concate-
nated group of VC objects.
• Performance tool start the Performance Tool. It can be started for a VC object. In the case of a
concatenated circuit, the VC object is selected from the Concatenated Components dialog.
• Faults tool starts the Fault View for the selected VC object. Use the Concatenated Components
dialog to select the component from a concatenated group.
• Active monitoring tool enables periodic polling of a VC object. The object is drawn in red if
there are faults or in dark blue if the performance has degraded. Black means that there has been
a communication error when the object was polled, and white means that polling has not been
performed for the object. A normal, well functioning object is shown in light blue. Only one
component of a group can be polled. The component can be selected from the concatenation
group.
• Node Manager tool starts the Node Manager tool for the selected node.
To use a tool, select it from the toolbox, then click on the VC object you wish to access.

http://slidepdf.com/reader/full/8000-inm-sr60-system-description 138/171
3 8000 Intelligent Network Manager Application Packages
The Concatenated Components dialog can be used to specify a component of a concatenated
group. Some of the tools require the selection of a single component. Cross-connection loops and
SNC switch always affect the whole group. Trail Trace can affect the whole group or a single
component. Other tools affect only a single component.
Intrusive Testing
Loops and SNC switch operations can disturb traf fic. If the circuit is a virtual trunk, a warning is
given. To appreciate the level of danger involved, consider a virtual trunk which carries hundreds of
circuits. If the virtual trunk is cut by a loop, all circuits will also be cut. If automatic recovery is
active, all of those PDH 1/0 circuits would be candidates for recovery, and that would severely tax
the servers and control channels of the network.
Intrusive testing differs from non-intrusive testing by allowing more tools and options. When the
selection tool is active and there is no active loop in the circuit, all locations where a loop can be
placed are shown by a green rectangle with an arrow inside. An active loop is shown in a yellow
rectangle, and all other possible loop locations are hidden while a loop is active. To activate theselected loop, click the Activate button. To reset an active loop, click the Reset button. To clear the
selection, click the Clear button. When a loop is activated, no faults are masked in the network.
If one exits from the tool while the loop is active, the loop will remain active in the network. The
test can be opened again for the same circuit, and the loop will be shown as active. It can be reset
normally then.
There are also two more tools in the toolbox than there was in the non-intrusive case, i.e. SNC
switch and Supervisory Unequipped:
• SNC Switch tool starts the SNC Switch Control Tool for the SNC branches. The tool is especially
useful in combination with the loop tool, as it allows the SNC/N protection to be bypassed so thatthe looped signal can be forced at the desired position. Normally a working SNC/N protection
would recover from the loop by using the non-looped portion of the circuit, if possible.
• Supervisory Unequipped. Node Manager can be used to create special VC objects called Su-
pervisory VC objects, which have a property of filling the payload with zeros. The signal sent
from Supervisory VC objects can be equipped with a trail trace, which distinguishes the signal
sent from the unequipped fault. The trail trace must be set separately.
This tool can be used to determine the points in the circuit where the Supervisory VC objects
will be connected. The actual connections are made when the test is activated, and removed
when the user resets the test, i.e. the connections are handled in the same manner as the
cross-connection loops.
There are no separate test results beyond those which can be seen from the different tools. The
test has no set duration (cross-connection loops have no time out possibility, and there is no fault
masking involved), but the database test catalog has a nominal 24-hour duration for the test. The
Test Reminder is not used by the SDH test tool.
The combination of trail trace, loop, supervisory unequipped testing and SNC switch can be used to
verify that the SNC protection works, signal reaches all parts of the circuit, and the correct faults are
generated at the endpoints under different conditions.
General Test Properties for ATM Virtual Paths
The Circuit Loop Test tool supports testing of point-to-point ATM virtual paths. As they can be
seen as circuits, the term ‘circuit’ is used of them, too.

The testing of ATM virtual paths is quite different from the testing of PDH circuits. All virtual path
tests are non-intrusive, since the normal transmission can continue in spite of the test activities.
The tests can have a slight effect on the overall performance though. The tests are based on the
ATM Operations and Maintenance (OAM) cells.
For the ATM Virtual Paths there are two tests: loop back test for data transmission testing and
continuity check test for permanent continuity monitoring. With the Circuit Loop Test window it
is also possible to define ATM virtual path segment endpoints.
The continuity check is a so-called permanent test, which means that it has no predefined test
duration. The test remains active until it is deactivated.
Testing Level
An ATM virtual path can be seen in different ways from the management point of view. You can
consider it as one entity from one virtual path connection endpoint to the other. In that case an
end-to-end level is in question. On the other hand, a virtual path connection can be divided intosmaller, independently managed portions, called segments. When a test is run in such a portion, it is
run at the segment level. Segment endpoints can be defined with the Circuit Loop Test facility.
The loop back test can be run either at the segment or end-to-end level. The end-to-end level
can be used if the other end of the test path is in external equipment. The continuity check testis always run at the segment level.
Available Resources
The testing resources for the ATM virtual path tests are so-called Link Termination Points (LTP).
There are two link termination points in one ATM access unit, one in the access interface side and
the other in the trunk interface side. The link termination points can also be defined as segmentendpoints.
For an ATM virtual path test, one link termination point is defined as a source and the other as a
sink. A source inserts test cells into the data stream. A sink receives those cells. Sometimes, as in a
loop back test, the source and the sink are the same link termination points.
A loop is a link termination point on the virtual path connection, where the test cells are looped
back to the original source. With a loop back test, this looping point can be a segment endpoint
or a virtual path connection endpoint. In the first case the testing is done at the segment level
and in the latter case the level is end-to-end.
Test Results
Test result for ATM virtual paths is the number of cells sent and received in the loop back test. For
continuity check, the results can be viewed in Fault Management as VPL (Virtual Path Link) down
alarm if LOC (loss of continuity) is detected.
3.5 Service Fault Monitoring Package
The Service Fault Monitoring Package allows the operator to monitor both TDM circuits and MPLS based services in the network. The operator may react to fault situations in the network based on the
priority of the services being affected. It also includes a service management tool that can be used to
bundle a number of TDM circuits, MPLS VPNs and VLAN VPNs into a logically managed service.

3.5.1 Service Fault Monitoring Windows
There are two Service Fault Monitoring related windows: Service Fault Monitoring (SFM)window and Service Fault window.
Service Fault Monitoring enables the real time supervision of all services, i.e. pseudowires, TDM
circuits, VLAN VPNs and IP VPNs that are assigned to a certain Service Category. A Service
Category is a collection of preselected services. It is possible to configure Service Fault Monitoring
so that only the selected service categories are displayed. In this mode, symbols are displayed in the
order they were selected. In addition to the predefined categories, an operator can select dynamically
Customers to be taken under monitoring. The fault status of categories and customers is displayed
in the Service Fault Monitoring window. The All Faulty Services symbol can be added to the
lower right-hand corner of the window. This symbol represents the total fault status of all services.
By default, the selected service categories and customers are saved on the configuration file and
thus remembered. This means that next time the previous view is automatically restored. One
workstation or Fault Server can be selected to save and update all faulty services in the database.
All faulty services and their fault status details of the corresponding category or customer are listed
in the Service Fault window. The appearance of Category and Customer symbols follow the same
characteristics as other objects in the FMS windows (color coding and blinking status directly
reflects the fault state of the object). From the Service Fault window an operator can open a Service
Fault Report window concerning a specific service and its faults.
3.5.2 Service Management
The Service Management tool allows the operator to manage a number of TDM circuits, VLAN
VPNs and MPLS VPNs as one logical service. The connections can be grouped together to form aservice object which can then be monitored as one entity in Service Fault Monitoring. It is also
possible to associate trunks and nodes with a service object.
In the Service Management window the operator can see all the components associated with the
service and launch associated tools with each of the components such as the Router, Circuit Loop
Test, VPN Provisioning, Packet Loop Test, etc. If fault monitoring has been enabled, the service is
monitored as one entity in Service Fault Monitoring and the user may also see the fault status of the
service in the Service Management window.
There is no restriction on how you group the connection in the network into services. It is also
possible to associate the same connection with several services. There are several options to group
the connections. The operator may group the circuits and VPNs such that all connections associated
with a certain base station are grouped together. Another option is to group all leased line trunkstogether and monitor them as one entity. If the operator uses some Ethernet switches managed by
the 8000 Intelligent Network Manager to form a management DCN, then the Ethernet switches
can be grouped to form one DCN service etc.

the history data on the database. The history data can then be viewed and analyzed later. In
the real-time performance monitoring, the counters are read from the network elements with an
interval of 5 to 600 seconds and drawn in a graph. This is intended for status verification and
trouble-shooting purposes.
For more information on the supported counters and supported history periods related to 6300, 7090,

3.6.2 Performance Statistics
The different types of supported performance statistics are listed below. For more information onthe available counters, refer to 8000 Intelligent Network Manager Online Help.
Data Granularity
The granularity of the collected data can be defined in more detail for the performance data types
supported by several interface types.
E.g. instead of collecting all PWE3 circuit statistics you can select to collect and store only Ethernet
PWE statistics, or instead of collecting all MIB2 type packet statistics only LAG can be selected.
This helps in all performance collection areas.
• There is less load on network elements (processing PM data queries).
• The DCN bandwidth usage (PM data transfer) is smaller.
• There is less load on Communication Servers (PM data processing).
• The size of the PM database is smaller.
• PM reports can be created faster.
The Polling Policy dialog can be used for configuring the granularity of the collected data. This is
currently supported for the 7100, 8600 and 8800 network elements.

3.6.3 History Data Collection and Ageing
Communication Servers take care of the data collection from 6300, 7090, 7100, 8600, 8800 and
mTera UTP network elements. The DXX Servers take care of the data collection from the 8100
network elements. The data collection runs continuously without operator intervention after the
server programs have been started.
Statistics are polled from the network elements continuously in the background according to a
polling policy configured for the Communication Servers and stored on the 8000 Intelligent Network
Manager database. The polling policy controls how the data is polled from the network element.
The recommended polling cycles depend on the amount of network elements, their furnishing,
network configuration and the performance of the Database Server.
Since the amount of performance history data can become huge in large networks, the old
performance data must be continuously removed from the database. The user may defi
ne for howlong the performance data should be stored on the database by configuring the ageing settings.
The Communication and DXX Servers will then automatically remove the old performance data
according to the ageing settings. The Performance Configuration tool can be used for configuring
the ageing settings, and it also shows the current database size of performance history tables.
Trend Calculation
Trend calculation is performed daily by Communication Server. The user needs to enable thetrend calculation, and configure the time of calculation. The trend calculation uses daily interval
history data as the input for the calculation. The daily interval history data contains history records
collected according to a polling policy (performance poll period) that has been configured by the
user in Network Editor. The results of the trend data calculation for each period are stored on the
8000 Intelligent Network Manager database, and the Performance Management Overview tool
can be used for reporting.
Raw Performance Data
Raw performance data, i.e. data that is stored and presented exactly as it is available on the network
element, is supported for the 7090, 7100, 8800 and mTera UTP network elements.
The data collection is enabled in the polling policy for the adapter. This data can be viewed using
the Node Manager tool. Data ageing is configured in the Performance Configuration tool.
3.6.4 Performance Reporting
Performance reports are typically available both in tabular and graphical forms. The user can
configure the reports in different ways. It is, for example, possible to report the totals of G.821/G.826
performance counters during different time periods in calendar time (weeks, months). It is also
possible to select multiple circuits and trunks to have network level down-time reports. Printouts,
however, are only in tabular form.

Packet Counter Performance Reporting
A graphical tool is available in the 8000 Intelligent Network Manager for viewing packet and cell based performance statistics in the 6300, 7090, 7100, 8600 and 8800 network elements. The tool
can be used both for history performance reporting as well as real-time performance reporting
(when applicable for the interface).
Performance interval history can be viewed in the graphical Performance Management tool. The
user may define the reporting period and the performance indicators to be displayed in the window.
There is a number of performance indicators to select from including: utilization, sent/received
octets/packets, errored packets, discarded packets for the interface or trunk interface.
The interval history data can then be exported to third party tools for further analysis through the
northbound interface of 8000 Intelligent Network Manager.
Web Reporter can be used to report performance interval history data.
Real-time performance monitoring polls the data from the network elements in real-time
according to a configured time interval, which can vary from a few seconds to several minutes.
The polled data is not stored on the database, only showed in the graphical window, which is
updated after each data poll. The real-time performance monitoring tool is useful in troubleshooting
situations in which a real-time picture of the current interface or trunk utilization is required to be
checked, e.g., how many packets are transferred, how many packets have errors or how many
packets are dropped. If the data needs to be analyzed with an external tool, it can also be exported to
a text file. With the data logging feature, it is possible to log polled counter values into a file in the
8000 Intelligent Network Manager workstation.
Exporting of the performance data showed in the Performance Monitoring tool, both in history
and real-time modes, can be done to a PDF document, clipboard graphics, graphics file or text file.The data is stored in the file in comma-separated value (CSV) format. The data in CSV format can
also be imported from a text file and displayed in the Performance Monitoring tool.
Performance Configuration is used for configuring the automatic removal of obsolete history data
from the database as well as for enabling the utilization fault monitoring and trend calculation.
3.6.5 Interface Utilization Threshold Monitoring
The Performance Management Package contains a very useful feature to monitor the utilization of
the interfaces (or an associated trunk interface) supported by 8000 Performance Management. The
collected packet performance data is analyzed and the utilization of the interface is calculated. If theutilization exceeds a user-defined threshold, then a fault is created and the user is alerted through the
fault monitoring tools. This allows the user to monitor the utilization of the network and to add
more capacity to the network before the congestion situations in the network become critical.
This feature is supported for the data from the 6300 and 8600 network elements.

3.6.6 Trend Analysis
The performance trend analysis looks at the utilization history data of performance statistics andcalculates trends based on this data. This feature helps the user to plan when a particular interface or
link is becoming full. The trend data calculation uses the linear least squares method for fitting the
measurement data into a straight line. Performance Management extrapolates the straight line to the
future to find out when the utilization exceeds the user-configured threshold. The trend data can be
calculated over different periods, e.g. one day, one week, four weeks or a custom period.
The Performance Overview tool reports the trend data and shows the following trend and
performance data.
• Trend Delta in period [and 24h]; the utilization change during a trend calculation period [and
during a day] to find out the fastest growing interfaces.
• Congestion date In/Out; the estimated date of congestion calculated for the user-defined conges-tion threshold. The congestion threshold can be changed. Sorting by date gives a report showing
which interfaces will congest first.
• Average Utilization In and Utilization Out during a period.
• Total amount of traf fic In and Out during a period.
The utilization trend calculation is supported for interfaces having utilization In or Out supported in
the 6300, 7090, 7100, 8600, 8800 and mTera UTP network elements.

3.6.7 Performance Overview Reporting Tool for 6300, 7090, 7100, 8600, 8800and mTera UTP Network Elements
The Performance Overview report is used for network level trend data analysis and reporting,
utilization reporting, and TDM and Abis group history reporting for the 6300, 8600 and 8800
network elements. Optical/OTN, TDM and port-level (Ethernet, POS) reporting is supported for the 7100 and mTera UTP network elements. Port-level (Ethernet) reporting is supported for the
7090 network elements.
The reporting application has a wizard making it easy to generate a report. Sorting and filtering is
supported, and the report can be saved to a file for further analyzing the history data. The graphical
Performance Reporting tool can be launched for more detailed reporting of performance history of an interface or specified layer.
The Performance Overview report helps to find congested interfaces or trunks by showing theutilization for all applicable interfaces. You can also look at e.g. Unavailable Seconds, Dropped
Packets and Delay counters in the corresponding report types for finding other problems in the
network.

3.7 Recovery Package
3.7.1 Recovery Management System
Recovery Management (RMS) is a centralized restoration system for the 8100 system network. It is
used for restoring user communication links if trunk or node faults occur in the network. Restoring
the user communication links can be done at the trunk level (trunk recovery) and circuit level
(circuit recovery). The RMS may keep a log of the incoming network faults and the RMS actions on
them. The operator may exclude some trunks or circuits from recovery actions or may disable trunk recovery or circuit recovery by setting RMS restrictions. The restrictions can by set for all trunks or all circuits or they can be set explicitly for some given trunk or circuit.
Trunk Recovery
Trunk recovery restores all connections in a specific trunk when there is a trunk failure. This is done
by reserving some of the trunks in the network for backup purposes.
If a trunk fault occurs in the network, RMS tries to remedy this fault by replacing the faulty trunk
with a backup trunk between the same two nodes. If such a trunk exists, the information flow
from the primary trunk will be switched to the backup trunk. This operation is called swapping.
If the primary trunk gets repaired, the unswap command switches back the information flow from
the backup trunk to the primary one.
If a backup trunk between the two nodes cannot be found, RMS tries to back up the faulty primary
trunk by a trunk route, which consists of two or more trunks between the end nodes of the primary
trunk. This means, that the information flow of the primary trunk will be redirected through other
nodes.
Since a trunk backup procedure is carried out much faster than the circuit recovery in a network,
RMS tries to restore network connections first by trunk recovery. If this fails, circuit recovery is
carried out. This behavior can be altered by the user by setting RMS restrictions.
Priority bumping at the trunk level provides low-cost recovery services. With priority bumping, the
backup trunks can be used by circuits that carry low traf fic class data. If a primary trunk fails, itis recovered by rejecting the low class traf fic of a backup trunk and no recovery action is started
for the bumped out low traf fic class circuits.
Recovery is not supported in the SDH network, but SDH trunk faults are administered by RMS
and RCPR.

3 8000 Intelligent Network Manager Application Packages
Circuit Recovery
Circuit recovery is used to restore individual circuits in the network and allows a more granular control over the circuits that are restored in failure conditions. Thus the capacity reserved for
backup purposes in the network can be minimized. Also, if trunk recovery fails, circuit recovery
can be used to restore the circuits in the failing trunk. The circuit types supported by circuit
recovery are: PDH 1/0 point-to-point (pp), point-to-multipoint (pmp), broadcast (bc), compressed,
swap and virtual grooming circuits.
Circuit recovery is done either by explicitly defining a backup route for the circuit or by having
the RMS calculate a spontaneous backup route for the circuit.
In addition, the capacity of primary trunks is not always allocated totally to user circuits. Normally,
all primary trunks contain free timeslots that may be used for route allocation if a circuit breaks
down. The timeslot capacity of a primary trunk is divided into three capacity pools: a primary
pool, backup normal pool and backup low pool. Primary routes and predefined backup routes areallocated from the primary pool. The spontaneous route capacity allocation depends on the circuit
priority and on the allocation mechanism. Circuits have four possible priorities: undefined, high,
medium and low. The allocation mechanism can be specified by the user. A spontaneous route is not
created for the circuit whose priority is undefined.
If a trunk fault cannot be recovered either in trunk or circuit recovery, RMS waits for a while and
retries the circuit recovery for those broken circuits until a successful recovery. The delay and
behavior between the periodical retries can be configured in order to allow a scalable solution
for networks with a large amount of circuits.
Recovery Control Program
The Recovery Control Program (RCPR) serves as the user interface to RMS. Using RCPR the
system operator can control all the RMS actions performed in the 8100 system network. For
example, controlling the logging of RMS actions, controlling RMS settings, setting timeslot
allocation rules, refreshing the fault state of a trunk and so on.
Server Redundancy
Recovery Management System uses a single centralized Recovery Server that provides the recovery
functionality. However, if increased reliability is needed, it is possible to install two Recovery
Servers. In case of an unrecoverable failure of the active Recovery Server, the other (standby)
Recovery Server takes over the recovery support. This feature can also be used when updating
hardware or software components in a Recovery Server.
It is also possible to switch servers at any time. Server switching operations can be initiated from
Recovery Control Program if you have the required privileges. The Recovery Server state can also
be viewed from the Recovery Control Program.
It is also possible to have the active server poll the standby server periodically. If there is no standby
server or it is not responding, a notification message appears in the Recovery Control Program.

3.8 Service Viewing Package
The Service Viewing package can be used to restrict the network views of the 8000 Intelligent Network Manager tools. This makes the management of the network easier.
3.8.1 Service and Circuit Component View
It is possible to select views that are based on circuits and customers. In these three views, Circuit
Components View, Customer Components View and VLAN Components View, only those nodes,
trunks etc. that are part of a selected circuit, or belong to a given customer, or are in particular
VLAN domain are shown on screen.
Circuit Components View
Fig. 93 Circuit Components View
The Circuit Components View shows the components, i.e. nodes and trunks, which are used for aselected circuit in selected regions. Also, components of several circuits can be selected in the view.
Target circuits are defined in a dedicated dialog, depending on their attached regions and the nature
of the circuit traf fic (region-internal, region-terminating or transit traf fic).

3 8000 Intelligent Network Manager Application Packages
Note that not all the trunks and nodes of circuits are necessarily shown in the view. The circuit
components in those regions which are not selected into the view are dropped from the display.
Using the Circuit Components View requires a license for component views. The view can be
activated/deactivated from the Backbone Overview mode or from the Regional Network View.
Customer Components View
Fig. 94 Customer Components View
The Customer Components View shows the components (nodes and trunks) which are used for
circuits of a selected customer or several customers in selected regions. In principle, this view is the
same as the Circuit Components View; instead of defining a set of circuits the operator selects a
customer whose circuits should be included. Also, the nodes which do not yet have circuits for thecustomer but which are dedicated to the customer, are included in the view.
Using the Customer Components View requires a license for component views. The view can be
activated/deactivated from the Backbone Overview mode or from the Regional Network View.

3.9 Planning Package
The Planning Package is supported for the 6300 and 8100 network elements only. It contains two
tools: Fault Simulator and Network Capacity Calculator for planning purposes. In addition, the
user may also plan the network in a simulation database with the normal 8000 Intelligent Network
Manager tools without having the actual hardware in place.

3.9.1 Fault Simulator
If a fault occurs in the 8100 system network, Recovery Management (RMS) will try to remedy it by using the backup trunks or the free time slots in the primary trunks. The network operator
can also issue recovery commands through the Recovery Control Program (RCPR), which is an
operator interface to RMS.
No matter how the recovery works, the bottom line issue is whether there are suf ficient backup
trunks in the network or primary trunks which contain enough free timeslots.
Therefore the question of how to suf ficiently and economically arrange primary trunks and backup
trunks is an important issue to be considered when a network is planned and when the performance
of an existing network is examined. Is it possible to test network recovery without collecting real
time data
Fault Simulator (FSMR) is designed to serve this purpose. It simulates the faults which may occur
in the real network and allows you to observe how RMS reacts to faults. This tool is therefore very
useful in finding potential shortages in recovery designs of the planned or existing network, such as
a lack of redundancy or inef ficient parameter setups. It is possible to run Fault Simulator only in a
simulation database. This guarantees that Fault Simulator never disturbs normal network operation.
Fault Simulator generates two types of faults, i.e. trunk faults and node faults. It saves the faults in
the database and sends them immediately to RMS through a named pipe.
Fault Simulator is easy to use. Faults are introduced and removed by double-clicking on a node or a
trunk with the mouse or via trunk and node lists in the corresponding dialog boxes. In addition,command scripts for fault generation can be recorded by Macro Manager (see chapter 3.13.1 Macro
Manager ).
3.9.2 Network Capacity Calculator
In the 8100 system network, digital signals are carried by trunks and circuit cross-connections are
accomplished by nodes. The maximum amount of information flow through a trunk is called total
trunk capacity, and the maximum cross-connect capability is called total node capacity. When user
circuits are connected in the network, they take both trunk capacity and node capacity. What has been
taken into use is called used capacity, while what has not been taken into use is called free capacity.
Reporting
Network Capacity Calculator (NWCC) reports the network capacity, including total, free and used
capacity of trunks and nodes when circuit connections are made according to the customer's demand.
It is capable of calculating traf fic between different nodes or locations and traf fic internal to, ending
to or going through a location. It can be used when planning a network or evaluating an existing
one. This tool helps the network operator in discovering shortage or redundancy of capacity in the
planning or existing network. Fig. 96 shows a snapshot of NWCC in use.

Fig. 96 Snapshot of Network Capacity Calculator (NWCC)
Planning
It is possible to use NWCC in network planning. New nodes, trunks and circuit connections can becreated. First, it provides, as does Network Editor, a set of basic objects such as nodes and trunks to
create a network. In addition to the nodes and trunks referring to a specific item of the 8100 system
network hardware, NWCC introduces ideal nodes and ideal trunks into the network. An ideal node
has unlimited cross-connect capacity, and an ideal trunk has infinite transport capacity. It is also
possible to preset a real maximum capacity for a node type in the initialization file, and NWCC can
use the preset value in calculations instead of infinite values. Given the endpoints and the capacity
requirement, it builds up circuit connections, as does Router, automatically or manually. In theautomatic routing mode, each trunk is given a cost and the shortest path between the endpoints is
found by the program which minimizes the sum of the trunk costs. The user can select one from
various types of cost available before starting automatic routing.
NWCC first reads the network data from the database, while it is used for studying the existing
network. It displays the network, calculates the capacity, shows the statistics, and prints the results.The user can edit the network by adding or removing objects and make new circuit connections.
However, the changes made by using NWCC do not affect the data in the database. NWCC saves
the data in a file instead of the database.

3.10 8100 Service Computer
The Service Computer (SC) is supported for 8100 nodes. It is used to monitor and control the
operation of a single node. Node Manager is the only 8000 Intelligent Network Manager user
interface component which can be used in the Service Computer. Therefore it has some facilities of
Fault Management and Performance Management. The Service Computer has no database support.
3.11 Partitioned Package
The purpose of network partitioning is to allow large networks to be managed by 8000 Intelligent
Network Manager regionally and still provide a centralized view of the entire network. Large
networks consist of smaller regional subnetworks and a backbone network connecting the
subnetworks together. Network division into regions is performed on a geographical basis. The
main interest of regional operators is to manage their part of the network with less attention being paid to other parts. More or less, these operators want to view their regions as separate networks,
which can be managed ef ficiently no matter how large and complex the overall network structure is.
The regions are also protected against unauthorized usage by other operators. Special access rights
are needed in order to operate in several regions e.g. when building up the inter-region connections.
Partitioning improves the structural organization of the network and hence the management
procedures. This facilitates the network building and helps the operators to understand the overall
structure. Partitioning also guides the operators to build up the network in a more comprehensible
way; nationwide meshed networks can be avoided.
Users can focus on particular parts of the network; they can create different network views by
selecting the regions and hierarchy levels they wish to display on the screen. The views can be
selected in the Backbone Network Overview (see chapter 3.11.2 Backbone Overview of Network )of the Network Editor, Router, Fault Management and Performance Management tools. The
selected view also restricts the sphere of operation of these network level tools (refer to the chapters
describing these tools).
Views for VPN Provisioning and Tunnel Engineering are configured using the Region Selection
for VPN Provisioning dialog in the Dashboard. For further information, refer to 3.11.6 VPN
Provisioning and Tunnel Engineering in Partitioned Network .
In addition to views based on geographical region and hierarchy levels of the network elements, it is
possible to select views that are based on customers and circuits. In these three views, Customer
Components View, VLAN Components View and Circuit Components View, only those nodes,
trunks etc. that belong to a given customer, or are part of a selected circuit, or are in particular
VLAN domain are shown on screen.
The relationships between the different choices of viewing the partitioned network are described
in the following chapters.
3.11.1 Hierarchy Levels for Partitioning
A large flat network is divided into regions on a geographical basis. Each node is attached to
a single region. In addition to this, different hierarchy levels are assigned to network trunks and
nodes. There are two ways of configuring the regions: the hierarchy levels of nodes and trunks can
be used in dividing the network into the access and backbone parts (access L1, backbone/access L2
and backbone L3), or into generalized regions simply dividing the network into smaller parts.

http://slidepdf.com/reader/full/8000-inm-sr60-system-description 161/171
3 8000 Intelligent Network Manager Application Packages
If access/backbone division is used, a single geographical region can contain both access and
backbone level components, or only backbone level components. This model supports the
assumption that a regional operator is often responsible for installing, monitoring and maintaining
all the network elements in a region, including the backbone network components.
The hierarchy levels are originally based on three categories of traf fic:
• region internal traf fic
• traf fic terminating at a region
• transit traf fic
These traf fic categories are used in defining the hierarchy levels for network trunks. The level of a
trunk thus indicates the nature of traf fic that is either used or intended to be used. The nodes are
also assigned similar hierarchy levels. These, in turn, are determined according to the hierarchy
levels of the connected trunks.
Router and Recovery Management obey the hierarchy levels when routing circuits or recoveringcircuits or trunks if the Partitioning Traf fic Rules are enabled. In addition, these tools obey the
regional boundaries via the so-called Partitioning Network Rules. In Recovery Management the
operator can also disable the Partitioning Network Rules for a specific trunk or circuit.
Fig. 97 shows an example of a partitioned network. Note that the backbone network is formed by
trunks at the level L3 and nodes belonging to the categories L2 or L3. The access network consists
of trunks and nodes of the categories L1 and L2. The figure is purely logical and does not present
any geographical relationships between the regions.

3.11.2 Backbone Overview of Network
Selections of view preferences can be made in the Backbone Overview mode. The operator canselect (mark) one or more regions. For each region the operator can select to view either backbone
components, access level components or both if the access/backbone division is used. This selection
of the level of interest can be different for each region. If generalized regions are used, the operator
can select the desired region.
Fig. 98 Backbone Network Overview (Access-Backbone Division Used)
From this Backbone Network Overview mode the operator can open either a Regional Network View(chapter 3.11.4 Regional Network View), a Backbone Network View (chapter 3.11.3 Backbone
Network View ) or an All Network View. The selection of the regions and the selection of the
level of interest only affect the Regional Network View and are necessary before activating the
Regional Network View. The Backbone Network View displays the backbone level components
independently from the selection of the level of interest. The All Network View shows all the nodes
and trunks as if the network was not partitioned.

The operator can restrict the Regional Network View to consist of only such network components
which belong to a given customer, or are part of a selected circuit, by activating the Customer
Components View (chapter Customer Components View) or Circuit Components View (chapter
Circuit Components View ) or VLAN Components View (chapter VLAN Components View).
These component views can also be activated/deactivated in the Regional Network View. A separatelicense is needed to activate these component views.
An operator with permissions limited to a single region can bypass the Backbone Overview mode
and go directly to the Regional Network View when opening a network level tool. (See chapter
3.11.4 Regional Network View)
3.11.3 Backbone Network View
Fig. 99 Backbone Network View
The Backbone Network View shows the backbone level (L3) trunks and the corresponding end
nodes, i.e. the backbone network. In case the operator has no backbone level access to a region, the
corresponding trunks and nodes are dropped from the view. Real management operations can be
performed in this view, e.g. the operator can zoom into the node with Node Manager, or activate
fault monitoring for the components shown.

Fig. 100 Regional Network View
The Regional Network View shows the access level and/or backbone level nodes and trunks of
selected regions. Different levels of interest can be used in different regions at a time; the selection
of regions to be viewed is performed in the backbone overview mode.
Each node must have a region and a hierarchy level in order to be shown in this view. The nodes andtrunks which are created in a VPN workstation are not shown in this view before a RNO has added
the required information to them. RNO can access such nodes and trunks in the non-partitioned All
Network View, which can be activated from the Backbone Network Overview mode.
A trunk which leaves a region to another region not shown in the view is represented by an arrow
symbol. Fig. 22 contains three such symbols for the backbone level (L3) trunk bundles.
Activating/deactivating the Customer Components View (chapter Customer Components View) or
Circuit Components View (chapter Circuit Components View) or VLAN Components View (chapter
VLAN Components View) is also possible in this Regional Network View.

3.11.5 Fault Management in Partitioned Network
In a partitioned network, different views are offered for operators in the network level tools to assistin focusing only on a relevant set of network elements at a time. In Fault Management System only
the faults originating from the components currently shown in the view are reported. Also, even if
the node is visible in the view, but the fault originates from an interface or a unit which is of no
interest for the current view (backbone/access aspects), the fault is filtered out. The rules for the
faults in different views are explained in the following chapters.
Backbone Overview
No faults are reported in this view.
Backbone Network View
The following faults are included:
• All faults from visible L3 trunks and L3 nodes.
• All faults from SCU, SXU etc. common units of visible nodes.
Regional Network View
The visible faults within each region depend on the level of interest defined (access/backbone/all)
for a region:
1. Level of interest is backbone for region BB1. The following faults are visible:
• Faults originated from L3 nodes in region BB1.
• Faults originated from common units (SCU, SXU etc.) of L2 nodes in region BB1.
• Faults originated from L3 trunk interfaces from L2 nodes in region BB1.
2. Level of interest is access for region ACC1. The following faults are visible:
• Faults originated from L1 nodes in region ACC1.
• Faults originated from L2 nodes, with the exception of L3 trunk faults.
3. Level of interest is all for region ALL1. The following faults are visible:
• All faults originated from all nodes in region ALL1.
Customer Components Network View
• Only those components and faults that are affected by the selected customers are displayed.
• Fault history reports cannot be retrieved in this view.
• Network change messages for the component view are not visible, but the main view will process
them.

Circuit Components Network View
• Only those components and faults that are affected by the selected circuits are displayed.
• Fault history reports cannot be retrieved in this view.
• Network change messages for component view are not visible, but the main view will process
them.
L3 Trunk Monitoring
A trunk which leaves a region to another region not shown in the view is represented by an exit
arrow symbol. In Fault Management System these bundles are also under fault monitoring. Two
different operational modes can be defined for the monitoring:
• full L3 trunk monitoring• partial L3 trunk monitoring
Full monitoring includes faults from both end interfaces of a trunk. Partial monitoring ignores the
L3 trunk faults in case the faulty interface is not within the selected regions.
3.11.6 VPN Provisioning and Tunnel Engineering in Partitioned Network
Partitioning for VPN Provisioning and Tunnel Engineering is enabled by default for the systems
that have already been configured for the generic partitioning support. The accessible regions and
the level of access allowed for the operator are configured in Regional Role Editor. Note that if
an operator profile has the Use global privileges to all regions or Super User option configured,
the operator automatically has access to all regions. When an operator logs in the Dashboard, theVPN Provisioning and Tunnel Engineering applications are automatically configured to show all
regions that the operator has access to.
The Region Selection for VPN Provisioning dialog is displayed in the Dashboard offering a
quick overview of the regions that the operator can access with VPN Provisioning and TunnelEngineering. In this dialog it is possible to select a set of regions to e.g.allow the operator to focus
on a specific group of network elements. Additionally, partitioning offers better performance as
without partitioning all existing VPN network element and tunnel data might get loaded into VPN
Provisioning and Tunnel Engineering. With partitioning only the data from regions with allowed
access is loaded.

Fig. 101 Region Selection
The rules regarding the allowed operations for an operator, .e.g. a connect or disconnect operation,
vary depending on which VPN or tunnel service is configured. In general, the operator needs to
have the Read/Write privileges to all regions where the involved network elements are located.
When a minimum number of regions is selected there may be elements in the VPN Provisioning
and Tunnel Engineering tools that are shown as Not in view. However, this does not impact the
operations that an operator is allowed to perform; e.g. the operator may still be able to connect a
VPN although some endpoints are shown as Not in view.
Note that if a set of regions changes while VPN Provisioning and Tunnel Engineering are running,
the applications must be restarted.
3.12 Unit Software Management Package
The Unit Software Management tools are used for updating the element software (ESW) in network
elements. Instead of updating the network elements one by one, these tools enable running the
update ef ficiently for tens or even hundreds of network elements. In addition, the tools provide ESW
reports for a set of selected nodes. The Element Software Management tool supports 7090, 7100
and 8600 product families. The 8100 Unit Software Management tool with reduced functionality
is used for 8100 network elements.
3.12.1 Element Software Management
The Element Software Management tool provides services to maintain element software files. The
software files are stored either in the database or FTP servers. The 8600 software files are stored in
the database whereas the 7090 and 7100 files are stored in the FTP servers.
The tool provides also ESW inventory reports for a set of selected nodes. Optionally, the report can
be enhanced with the detailed software information by reading the data directly from the network
elements. For 8600 nodes, the tool provides additionally unit-based reports. Reports can be saved to
a file in CSV format allowing to import the information to another reporting tool.

The software update in the network elements is based on download plans which can be created with
this tool. Each download plan supports a product family specific update procedure. The plan defines
a set of network elements to be updated. For each network element, the software file and version
can be selected. In addition, a set of run-time options for the plan can be defined. It is possible to
schedule the download task to be run later at the time defined in the plan. The software update can be done fully automatically, or the update procedure can be stopped in some update phase, e.g. after
transferring the file but before activating the software. This allows continuing the software update
manually. Before activating the plan, the user can select which network elements in the plan will be
processed enabling the user to take more control over the update procedure.
The tool provides a copy operation for creating new download plans based on the old plans. A plan
can consist of hundreds of network elements, and using this copy functionality a lot of manual work
can be avoided. The plan can be modified by adding new elements to the plan or by removing
old and obsolete network elements. The tool also enables easy modification of the used software
files and versions in the plan.
Normally the software of the network elements is updated as a whole including all units in the
network element. This can be done by using software packages including software and possibly
FPGA images for all types of units. However, the tool supports also a unit-based software update
with unit specific software files for some unit types.
When the download plan has been activated and the corresponding download task created, the
update procedure can be monitored by following the status columns in the plan. For each network
element in the plan, the tool reports the current update stage, state, operation and possible problems.
During the update procedure the download task can be temporarily paused or completely stopped. A
stopped task can be restarted again and the procedure will continue from the phase it was before the
stop operation. Also a completed task having some problems can be restarted.
The download task is performed stage by stage according to the product specific update procedure.
On each stage a set of network elements are processed in parallel speeding up the whole update procedure. The level of concurrency can be controlled by defining the corresponding options in the
download plan.
The completed download plans can be removed from the database but they can also be kept in the
system as documents about the software updates in the network elements.

3.12.2 8100 Unit Software Management
For the 8100 system nodes, the 8100 Unit Software Management tool provides features to get
reports on software and hardware versions of units of a selected type in a selected set of nodes.
The user can automatically download new software into several units selected anywhere in the
8100 system network. Downloading new software into different units can be done in one session,
and the events of download progress can be saved into a file for further review. The unit and file
information in the main window and in the download dialog can be saved in a file or printed on a
printer. The software version, serial number of units and the date of downloading are also updatedinto the database.
To prevent any errors in the unit software download, the tool also checks for inconsistent software:
the name of the software file is compared to the unit hardware type, as well as, checking the
software version numbers.
The time required for downloading can be reduced by opening several download sessions
simultaneously. You can start several download tools for different areas of the network in one or
more computers. In one computer, the recommended maximum number of tools is four, which thenalso requires four unique file names for download events to be saved. Unit Software Compatibility
Checker checks the compatibility between the GMU base unit software and other unit software
in a node.

3.13 Macro Package
3.13.1 Macro Manager
Macro Manager is an additional tool for managing the network by special macro commands. The aim
is to speed up the network management processes in the case of a large network and a huge number
of network objects (nodes, trunks, circuits, etc.). The interactive graphical interface is replaced by
macro commands. Additionally, you can create your own Graphical User Interface for your macros
using the Application Development Toolkit, see chapter 3.13.2 Application Development Toolkit.
You can reuse the sample macros delivered with the program or record your own macros. The macro
language supports high-level control structures, such as variables, conditional statements, loops and
submacro calls. It can also handle database change messages and supports file operation, threading,
scheduling, polling and printing. These features allow you to write complex programs in Macro
language to automate sequences of 8000 Intelligent Network Manager operations.
Node Manager macros are used for setting different kinds of hardware parameters. Most of them
also update the database. Network Editor macros are used to build and edit the network in the
database. Router macros are used for managing circuits. Fault Simulator macros are used for adding
and deleting node and trunk faults in the database. Note that simulator macros can only be run in
a simulation environment. Topology macros are used for node inventory and trunk provisioning.
Service provisioning macros are used for IP VPN and pseudowire provisioning. Discovery macros
are used for discovering nodes, IP VPNs and pseudowires.
Add-on macros are macros that can be launched directly from the 8000 Intelligent Network Manager
GUI. An add-on macro can be associated with specific NE objects (for example, interfaces of a
specific type) and then launched for those objects via pop-up menus in Node Manager.
Refer to the Macro Manager online help for details.
3.13.2 Application Development Toolkit
The Application Development Toolkit is a platform for the graphical user interface (GUI) and
network level programming. It is a high-level programming language with a class library that
gives you a network level object model of the 8000 system network. It includes the 8000 system
network, visual (GUI) and parameter objects. With Application Development Toolkit you can create
your own windows and dialogs to view and configure parameters of the 8000 system network.
With Dialog Editor you can design your own dialogs. Application Development Toolkit supportsstandard GUI application features, window and dialog controls like menus, buttons, edit fields
and list views with columns.
Application Development Toolkit requires a separate license. It uses the services provided by Macro
Manager and thus requires that the Macro Manager license is active in 8000 Intelligent Network
Manager.
The functionality provided by Application Development Toolkit and macros provided by Macro
Manager work seamlessly together. The window macro applications developed with Application
Development Toolkit can be run separately from Macro Manager.

3.14 Web Reporter
The Web Reporter tool is used to access information in the 8000 system network through the intranetor the Internet. In addition to the traditional browsers, there is a dedicated Web Reporter application
for mobile devices (for Android, iOS and Windows) providing an easy-to-use GUI. The resolution
and scale have been optimized for the mobile version. The same logic is being used in both browser
options for login, navigation tree and report filtering.
Web Reporter enables fast distribution of information without the need to consult the personnel
operating the network. For example, customer service staff and sales personnel can view circuit
capacity, availability, pseudowire and tunnel information, free node interfaces or faults when a
customer calls. Field service personnel can see where a fault is located and plan repairs accordingly;
they can also receive node information when installing new hardware and services. Management
can monitor the quality, performance and observe the size and contents of the network. Also the
network operators benefit from the clear and comprehensive reports. End customers may be
interested in monitoring the availability of their circuits and pseudowires. Regarding the secure
communication over the network, Web Reporter supports HTTPS providing the encryption of the
communication between a client and a server.
The system contains a number of predefined reports that the user can schedule. The output format
for these periodic reports is HTML, PDF or Excel.
