APPLICATION PPLICATION OF MSTP 4.1
Application of Ethernet Service EPL: Ethernet Private Line Fig 4-1 EPL
MSTP access node accesses data of important clients via FE interface, as shown in the above figure. After adapted with GFP encapsulation rate rather than L2 switching, user data is mapped into SDH VCG, then transmitted from end to end via SDH network to destination node. In the above process, link bandwidth depends on VCG. It is occupied only by a user just like a physical private line, so end-to-end QoS of services can be ensured. Different from conventional private line, MSTP can employ LCAS protocol or NM configuration to adjust link bandwidth flexibly and dynamically, and support traffic control. EPL can ensure transparent transmission of Ethernet service, e.g., Ethernet MAC frame and VLAN label. Ethernet service can be protected in SDH protection mode.
EVPL (Ethernet Virtual Private Line) Fig 4-2 EVPL
In the above figure, user data are accessed via several user ports, and share the bandwidth of one network-side port (WAN port), i.e., one physical private line. The bandwidth at WAN port can also be configured. It is required to adopt Confidential and Proprietary Information of ZTE CORPORATION

VLAN technique to ensure service intervals between different user ports. The advantage of the scheme is that all user ports can share bandwidth at WAN port, CIR and PIR should be configured to ensure QoS at user ports, and user Ethernet service adopts SDH physical-layer physical-layer protection. EPVL is applied to virtual private line interconnection of different users (interconnected via VLAN) between two nodes. For example, VLAN1 and VLAN2 are two branches of industrial and commercial systems, and VLAN3 and VLAN4 are two branches of tax system.
EPLAN (Etherrnet Private LAN) Fig 4-3 EPLAN
The services at 3 branches can be converged to headquarter via star network composed of SDH timeslot links. MSTP at central node is embedded with L2 switching function. For central converged services, link bandwidth from branches to headquarter is exclusive, so end-to-end QoS can be ensured. And the network is highly reliable. When a branch fails, services at other branches still work. User Ethernet service adopts SDH physical-layer protection. Fig 4-4 EPLAN
The services between 3 branches and headquarter can form Ethernet shared ring through SDH virtual connections via VCAT. But it is required in the configuration that each MSTP node in the ring support L2 switching and STP. In this way, less fiber bandwidth is occupied when large quantities of nodes are available in the ring. In order to avoid unfair bandwidth allocation among the nodes, the supervision is required to control LAN port traffic at each node. The ring adopts SDH physical-layer protection. Because Ethernet ring crosses several SDH rings, STP protection can also be used. Fast STP can reduce protection time to less than 3 seconds.

EVPLAN (Ethernet Virtual Private LAN) Fig 4-5 EVPLAN
The services between branches and headquarters of company A and B can form virtual Ethernet shared ring through SDH virtual connections via VCAT. But it is required in the configuration that each MSTP node in the ring support L2 switching and STP. The services of two companies are isolated by VLAN. In this way, less fiber bandwidth is occupied when large quantities of nodes are available in the ring. In order to avoid unfair bandwidth allocation among the nodes, the supervision is required to control LAN port traffic at each node. The ring adopts SDH physical-layer protection. Because Ethernet ring crosses several SDH rings, STP protection can also be used. Fast STP can reduce protection time to less than 3 seconds. EPL is applied to private line interconnection between two users.

transmitting other services. In addition, ATM transparent transmission on SDH network can connect several VP-RINGs in serial to form a mixed ring.
4.3
Application of RPR Service The deepened function of RPR by ZTE 1. The RPR board of S330 has integrated RPR MAC function following the IEEE 802.17 standard 2. RPR board (RSEB) can build up 1.25G RPR ring ，and its bandwidth towards Backplane is 2.5G. 3. The interface of MAC layer is 4×FE ＋2×GE，it can carry out the n×FE to FE ，n×FE to GE and n×GE to GE converging. 4. Using powerful function of service classification the service can be differentiated based on the interface or VLAN. 5. Powerful function of flow control: The maximum number of data streams carried on the RPR ring is 1000, every data stream can be set as Class A0, A1, B, and C, also the flow control parameter of stream can be set and the granularity granularity of flow control is 20Kbps. 6. The station supports plug and play ，and the configuration is very simple, RPR ring can find the incorrect fiber connection voluntarily. voluntarily. 7. The wrapping and steering protection is available on RPR layer, and the conflict of protections between SDH layer and RPR layer can be avoided by setting switching time delay. 8. The capability of MAC address is very large, every station can learn and store 64,000 MAC addresses ， it can avoid the unnecessary flood frame and reduce the waste of bandwidth when building up complex network. 9. The fairness arithmetic of autonomous intellectual property can share the bandwidth properly, make the bandwidth converge quickly and make the bandwidth fluctuation little. 10. CID (Customer Identifier Domain) in RPR. can carry out double isolation as CID plus VLAN ID, so it can isolate the data belonging to the same VLANs in different VPN domain and carry out EVPL and EVPLAN in network.

Chapter 5 – Networking and Protection
For ZXMP S330 equipment, one or two –48V power cables are introduced to the cabinet via the air switch in the power distribution box. When two groups of equipment room power supplies are introduced to the device, the power supply works in 1+1 protection mode to make sure that the device works well in the case of either the power group failure.
Inside-cabinet power protection The -48V power is filtered in the power distribution board in the power distribution box to provide power for the sub-rack and fan shelf. ZXMP S330 uses two power distribution boards for power distribution. The two power distribution boards can provide power jointly or separately.
Board power protection The board adopts the distributed power supply mode to reduce the power affect between boards to zero. All boards have over-current and over-voltage protection. Power polarities inversely connected: Use fuse for protection. protection.
Cross-switch protection ZXMP S330 uses two CS boards. The 1+1 protection for the CS board is realized. Namely, two CS boards, i.e., active and standby, can be configured in the system. In case of failure, the NMS sends commands to control the switching of the CS board.
Clock protection ZXMP S330 uses two SC boards to achieve the protection for the clock. To ensure reliable synchronization and timing, the SC board may work in the hot backup mode or independently, independently, that is, two system clock boards, i.e. active and standby, may be configured in this system. When both boards are in position and work normally, only the clock of the main system clock board is output to the backplane. In case of failure in either of the boards, the clock is switched to the other SC board.
1:N protection for the tributary board The system has totally twelve slots for the tributary board, which are divided into left and right groups. Each group provides the 1: N (N ≤5) protection for the E1/T1 and FE tributary board and the protection board can be inserted in any service slot in the local group. It also provides the 1: N (N ≤5) protection for the E3/T3 tributary board and EL1 board and the protection board must be inserted in the designated position. The 1: N protections for the service boards in the left and right groups are independent from each other, and different protection modes may be supported.
Automatic Laser Shutdown function All STM-1/4/16 optical interfaces of S330 support the ALS function and satisfy G.664 standard. The course of ALS is illustrated in Fig.5-2. When the cable is broken at A point, the receive port detects the loss of continuity of optical transmission signal (LOC-OTS) at R2, which will cause T2 transmission port to shut down, and the LOC-OTS detected at R1 also causes the T1 transmission port to shut down. In such way, it guarantees the optical power, in the OTS section at A point where failure occurred, being in safety. Fig.5-2 the ALS principle

After it is reconnected reconnected in the OTS section, resume the transmission within the OTS section by restarting automatically or manually. (Attention: when it disconnects or after an (unsuccessful) restart, do not enable the restart within 100s.)
5.3
Network-level Network-leve l protection ZXMP S330 equipment can realize all the network protective modes specified by ITU-T: 1. MSP1:N, 2. 2F UPSR, 3. 2F BPSR, 4. 4F BPSR, 5. DNI protection, 6. SNCP, 7. Unique Logical Sub Network Protection scheme ： ZXMP S330 presents and implements a very new network protection concept on the basis of ITU-T recommendation: virtual logical subnet protection. This function can meet the requirements of more complex network structure, enhance the network security and increase the bandwidth utilization, such as Multi-ADM (M-ADM) and M-ADM with subtending rings. The logical subnet is the result of dividing a network according to the logic topology and logical capacity on the basis of the physical network. One physical network can be divided into several logical subnets ，the logical subnets can be further divided by service type, capacity, network topology and protection mode as shown in Fig. 5-3. The protection and management of each logical subnet is independent of one another. Fig.5-3:
