1.2 1+1 Protection for Cross-connect Unit and Timing Unit

The cross-connect unit and timing unit are provided by the GXCS/EXCS boards. GXCS/EXCS boards employs 1+1 hot backup for protection of crossing unit and timing unit at the same time. When the active crossing and timing units are in normal working mode, the standby crossing and timing units are in standby working mode, not engaged in cross-connection function of service, and not providing timing to the system, while the setting and timing configuration of the cross matrix are completely the same with the active units. When the standby units receive the information indicating abnormal performance of the active units or a switching command is sent by the NM, they will immediately take over the job of the active units, setting themselves into the active working mode and sending out a switchover alarm.

1.3 Protection for SCC unit

The SCC unit of OptiX OSN 3500 is provided with 1+1 hot backup protection. The standby SCC unit is in standby working mode when the active one is in normal operation.

1.4 Protection for Power Supply System

The OptiX OSN 3500 can access two –48V DC working power supplies through the two PIU boards. If either one of them goes faulty, the other one will operate to ensure the normal operation of the equipment.

1.5 1:N Protection for 3.3V Board Power Supply

The OptiX OSN 3500 provides 1:N power protection for other 3.3V board power supplies through the power backup unit of the AUX board. When failure occurs to the board power supply, the backup power will take over the power feeding job to ensure normal operation of the boards.

1.6 Intelligent Fans

For heat dissipation, the OptiX OSN 3500 adopts three intelligent fans, whose rotational speeds can be adjusted freely. The power supplies for these three fans serve as backup for each other. With the fan failure detection function, once one of the fan modules goes faulty, the other two will operate at their full speeds. The running status of the fans can be indicated by the corresponding indicators on the front panel.

1.7 Abnormality-Specific Service Protection

1. Power failure in software loading process

Application program and data have the check function. In the case the loading is

19

interrupted, the BIOS will not start the unfinished program and data until they are successfully loaded.

2. Providing over-voltage and under-voltage protection

The power board is designed with a lightning protection mechanism to effectively reduce the damages that may be possibly caused by transient high-voltage such as lightning. When the voltage is over low, this board will automatically reset the Center Processing Unit (CPU). The software will re-initialize the chips. The software will provide a mirror protection on important memories that may affect the services. In the case the voltage is not stable, which results in memory value changes, the values can be recovered to normal. In addition, when the voltage is too low, the power system will automatically cut off the active power to protect the system.

3. Providing board temperature check function

Temperature detection circuit is provided on boards that generate more heat. When the ambient temperature detected is too high, an alarm is generated to remind the maintenance personnel to clean the fans.

2 Network Level Protection

2.1 SDH Trail Protection

For the OptiX OSN 3500, trail protection may occur at either the multiplex section (MS) or the path in the modes of linear MSP and multiplex section protection (MSP) ring.

1. Linear MSP

Linear MSP is mainly used in linear networking topology. The OptiX OSN 3500 supports 1+1 and 1:N (N ≤14) protection schemes in the point-to-point linear networking topology. In the 1:N protection mode, additional services are supported to be transmitted on the protection system. In the linear MSP scheme, the switching time is less than 50ms as specified in ITU-T Recommendation G.841.

2. MSP ring

The OptiX OSN 3500 supports shared optical path protection of two MSP rings. That is, it supports two MSP rings on one optical interface. The OptiX OSN 3500 supports 2-fiber MS shared protection ring, with the switching time less than 50ms, as specified in ITU-T Recommendation G.841. Moreover, in line with ITU-T Recommendation G.841, the OptiX OSN 3500 supports 4-fiber bidirectional MS shared protection ring comprising ring switching and span switching. It other functions are similar to those of the 2-fiber bidirectional MSP.

2.2 SDH SNCP

The support of OptiX OSN 3500 to SNCP is fully in line with the requirements stipulated in ITU-T Recommendation G.841. Even multiple service switching events occur at the same time, the switching time can still be less than 50ms.

2.3 Protection for Interworking Service on Rings

When there are more than one interworking routes existing between the rings, inter-ring service protection can be enabled. For two rings in Dual Node Interconnection (DNI) mode, ITU-T Recommendation G.842 specifies the protection scheme for interworking services in rings with different protection schemes (such as SNCP or MSP). The support of the OptiX OSN 3500 to the DNI mode fully conforms to the requirements of ITU-T Recommendation G.842.

2.4 Fiber-shared virtual path Protection

The SDH network protection mechanism specified by ITU-T is primarily based on ring networks. As for the mesh networking mode, definitely they fail to enjoy satisfactory protection modes, as they cannot be detached into a series of optical ring networks.

Protection



21

By virtue of features of the OptiX series products, together with the in-house developed SDH cross-connect chips and powerful higher-order and lower-order cross-connect matrix, Huawei promotes a ring networking mode based on the path layer. That is, the protection for ring networks is based on higher-order or lower-order paths. From this point of view, the mesh network can be considered as overlapping of ring networks comprising various paths. Once independent protection for respective paths can be provided, the service on the whole mesh network can be protected accordingly.

2 Application of Ethernet Service

With the capability of accessing Ethernet service integrated into the SDH platform, the OptiX OSN 3500 can transmit both the voice service and data service. The OptiX OSN 3500 supports service convergence and L2 switching, as well as the VLAN function specified in IEEE 802.1Q. It also supports the L2 VPN service. With the special frame format, the OptiX OSN 3500 can be deployed in the fields such as MPLS, VLAN and L2 MPLS VPN, satisfying the user’s requirements for private line and network.

1. Transparent transmission of the point-to-point Ethernet service in the chain

The OptiX OSN 3500 can be deployed in the chain network for point-to-point transparent transmission of the Ethernet services, as shown in Figure 7. In this figure, service A is transparently transmitted from Ethernet Port 1 of NE1 to Port 1 of NE3, passing through VC-Trunk A. Service B is transparently transmitted from the Ethernet Port 2 of NE1 to Port 1 of NE2, passing through VC-Trunk B. The services A and B can be of either FE service or GE service.

2. VLAN convergence of Ethernet service in the chain

Supporting the VLAN function specified in IEEE802.1Q, the OptiX OSN 3500 provides private network service. It performs flow classification to services according to the Ethernet port and VLAN ID. Up to eight IEEE802.1P-compliant priorities can be set according to the flow classification result. The OptiX OSN 3500 isolates services of different users through VLAN to achieve security purpose. As shown in Figure 8, VLAN 1 and VLAN2 of Company A share VC-Trunk 1 with VLAN 2 of Company B, and the services on VLAN 1 of Company B are transmitted through VC-Trunk 2.

classification is performed to the Ethernet service according to the port and VLAN ID to distinguish different VLANs that Company A and B belong to respectively. Up to eight IEEE802.1P-compliant priorities can be set according to the flow classification result. The OptiX OSN 3500 isolates services of different users through VLAN to achieve security purpose. In the figure below, VLAN 1 of Company A shares a VC-Trunk with VLAN 1 of Company B, and VLAN 2 of Company A shares a VC-Trunk with VLAN 2 of Company B, and VLAN 3 of Company A shares a VC-Trunk with VLAN 3 of Company B. All services of Company A are converged to NE1 and output from an FE/GE interface to Lanswitch for processing.

5. L2 switching of Ethernet service

The OptiX OSN 3500 supports L2 switching of the accessed Ethernet data, which can be transferred according to their destination Media Access Control (MAC) addresses. For example: As shown in Figure 11, respective LANs of Company A and B are connected to four nodes. The Ethernet service between the nodes is not of a fixed point-to-point type. For example, a user of Company A connecting to NE3 may want to communicate with users of Company A connecting to other three NEs. That is, the flow direction of services is not definite. The Ethernet L2 switching function provided by the OptiX OSN 3500 can be employed to solve such a problem. For example, an Ethernet MAC address transfer table will be formed in the system when relevant settings are made to NE3. With the self study function of the system, this table can be updated

27

periodically. Then, according to their destination addresses, the data of Company A and B accessed at NE3 will be transmitted to their destinations via checking the transfer table and selecting corresponding VC-Trunks or sharing the same VC-Trunk. By this way, the system configuration is significantly simplified and the bandwidth utility is improved, and the corresponding maintenance and management becomes convenient for the operator.

7. EPL/EVPL Service

The OptiX OSN 3500 adopts the Martini modes to construct the MPLS L2 VPN and provides EPL/EVPL service. As shown in Figure 13, the system will check the Port + Vlan ID table and add the external label (Tunnel) and internal label (VC) it gets to the accessed Ethernet frames. Data transfer in the network is based on the external label, which will be discarded at the Provider Routers (P) equipment at the last hop. Then, the data will be transmitted to the corresponding Provider Edges (PE) equipment, which transfers the data to corresponding port according to the internal label. The OptiX OSN 3500 integrates the function of P equipment and PE equipment.

8. EPLAN/ EVPLAN Service

The OptiX OSN 3500 adopts the Martini mode to provide the EPLAN/ EVPLAN and implement the multipoint-to-multipoint connection of user sites. From the angle of user, the EPLAN/ EVPLAN network is a big Vlan where the user service can be converged. As shown in Figure 14, when the user’s Ethernet frame (with the source address being MAC H, and the destination address being MAC A, B or C) enters the PE equipment, the system will check the Layer 2 transfer table and attach the internal label (VC Label) it gets to the frame. Then, the frame is transferred to corresponding tunnel, where it is attached with the external label (Tunnel Label), and different Label Switch Paths (LSPs) are set up according to different addresses. The Ethernet frame is detached from the Tunnel Label when leaving the P equipment, and then transferred to corresponding PE equipment, where the VC Label is detached. After that, the Ethernet frame is transferred to corresponding output port according to the Layer 2 transfer table.

2 Equipment Management

The OptiX OSN 3500 is uniformly managed by the NM system. Through the Qx interface or MML interface, the NM system can implement management, maintenance and test to the whole optical transmission system in terms of fault, performance, configuration and security. The NM system improves the quality of network services, reduces the maintenance cost and ensures rational use of network resources. Huawei Technologies Co., Ltd. provides telecommunication operators with a whole series of optical transmission systems, which can be used on networks of different layers. To manage sub-network, area network or national network efficiently, the NM system is required to feature basic operation and maintenance functions, and the monitoring and management capability on the optical transmission network as well. According to the Telecommunications Management Network (TMN) network management hierarchical model, the telecommunication network management is divided into network element layer (NEL), NE management layer (EML), network management layer (NML), service management layer (SML) and business management layer (BML). The NE management system manages NE equipments within one subnet, while the NM system implements the network layer assignment, fault monitoring, performance analysis, resource analysis, circuit dispatching, etc. in a large-scale network. To adapt to network management of different scales and levels, the OptiX iManager series products of Huawei consists of the local maintenance terminal, NE management system, regional network management system and network level NM system. These products cover the applications of the TMN from the NE management layer, subnet management layer to the network management layer, and contain part of the service management layer functions. All the OptiX iManager series products can perform uniform management on SDH, WDM and OSN equipments. With these products, Huawei is able to provide telecommunication operators with a complete package of network management solutions for single equipment, single service to large scale and multi-service networks.
