• Interworking in optical transport networksSignalling concepts: analysis and test them,

contribution to specification

– GMPLS for IP-based control plane (IETF)

– ASON / ASTN (Automatic Switched Optical/Transport Network, ITU)

– UNI for user controlled signaling and E-NNI

(Optical Internetworking Forum, OIF)

– Interoperability at UNI/NNI (OIF)

– I-NNI-GMPLS-Interface



• First Signalling-Results– GMPLS with Soft-Perm-Conn at Alcatel-CC1678 in operation

– OIF-E-NNI at Alcatel-CC1678 and Sycamore-CC SN16000 available

– OIF-UNI 1.0,R2, network side at Alcatel-CC1678 available

– OIF-UNI 1.0,R2, network side at Sycamore-CC-SN16000 available

– OIF-UNI 1.0,R2, client side: Late 2005

– OIF-UNI 2.0, planned for 1Q 2006 at Alcatel and Siemens CC

– Interworking tests of OIF-E-NNI between Alcatel-CC1678 and

Sycamore-CC-SN16000: some problems (interpretation of Unicast/Multicast OSPF-Packets when using IP-tunnels)



• Provision of Ethernet-Service over SDH with bandwidth adjustment (New SDH: GFP, LCAS, VC).– GFP: Generic Framing Procedure (ITU-T G.7042), method to transport

data packets (e.g. Ethernet) over SDH– LCAS: Link Capacity Adjustment Scheme (ITU-T G.7041), dynamical

bandwidth adjustment for SDH-links (variable VC4-container)– Virtual Concatenation (VC) instead of Continuous Concatenation (CC):

VC4-Container may use different ways in the transport network

• First New-SDH-Results– Basic tests/interworking between Alcatel-CC-1678, Siemens-CC-

hiT7070 and ADVA-GE-MUX-1500 successful – LCAS tests in 4Q 2005

Equipment (Alcatel-CC 1678) or directly with 10GE-LAN-Phy– Test: Performance, Functionality

• First L2-Results– VLL and VPLS: OK

– H-VPLS: Problems, Alcatel/Riverstone not fully compatible

– Interworking Ether Flow Control between L2/SDH-Switches: OK

– QoS-Fkt. for b/w limitations (Shaping,Policing;Ingress,Egress): OK

Project Goal Middleware

• Implementation of an operational environment for PC-cluster based on UNICORE– UNICORE supports the operation of a Compute-Grid

– Interoperability with Globus-toolkit and compatibility with OGSA (Open Grid Services Architecture) is planned

• Development / Portation of missing components– Development of a Meta-Scheduler based on Global Grid Forum

Standards (Grid Resource Allocation Agreement Protocol)

– Portation of MetaMPI and integration in UNICORE

– Adaptation/upgrading of local tools to connect and analyse distributed applications

– Development of high-performance parallel-I/O-interfaces (main

memory, file server)


Project Goal Applications (1)

• Usage/upgrading of (existing) applications with high and dynamical transfer requirements (e.g. e-science / Grid)– Several GE-tunnels per application – Dynamical requirement of bandwidth with guaranteed QoS – User controlled networks (E2E)

• Integration of real users – Variable requir. (time,size,quality) for „stress-test“ of network

equipment

• Based on experiences with new networks– Creation of new ideas for applications – Motivation of user groups for GRID-technology

• „VIOLA-Participation“ (DFN, TSI, Uni Erlangen) in FP6-projects:– GN2 - Geant2– MUPBED - Multi-Partner European Testbeds for Research

Networking

• The testbed VIOLA forms the national base to contribute successfully to international projects

• Interested for cooperation with similar projects/activities in Europe and elsewhere


Status (1)

• Testbed implementation was finished early 2005:– circuits are connected (including connection to G-WIN/GEANT)

– equipment is installed;

– network management is operational

• Work items of „Transport & Signalling“ have been started:– I-NNI: Available for Siemens-CC-hiT7070

– E-NNI: Available for Alcatel-CC-1678 and Sycamore-CC-SN16000

– E-NNI interoperability tests between Alcatel & Sycamore

Status (2)

• L2-Test/Operation:– VLL/VPLS interoperability tests with Alcatel & Riverstone: OK

– H-VPLS interoperability tests with Alcatel & Riverstone: Some problems

• Initial version of middleware is deployed, Integration of new middleware components in progress

• Application projects have finished preparatory work• First “runs” over the network have been made

Applications are beginning to stress network & middleware.
