Part III Feature Overview of MSTP+ Products


What Is MSTP+? MSTP+ = MSTP + PTN

MSTP equipment can be smoothly upgraded to MSTP+ equipment, which has the PTN features. That is, MSTP can be smoothly upgraded to PTN.

The focus of the upgrade is to reconstruct the cross-connects for MSTP equipment.

With the TDM features unchanged, the new cross-connect boards integrate the core chips used for the PTN equipment. Then, one cross-connect board has dual cores. This enables profound evolution of MSTP.

MSTP+ equipment derives from MSTP equipment and is compatible with all the features currently available on MSTP .

MSTP equipment can be upgraded to MSTP+ equipment by alternatively upgrading the active and standby cross-connect boards. In addition, MSTP+ equipment supports the packet plane, where the data services can be directly added. This solves the problem of inability to multiplex SDH rigid channels.

Dual-core: TDM core + PTN core, processing TDM and packet services at the same time .One-heart (EOD): Data services freely flow. During upgrade, the TDM plane and packet plane can seamlessly interoperate.


Values of MSTP+ Products

• Provides and optimizes the IP RAN solution.– Is oriented to broadband on mobile networks.

• Transports data services, which require high bandwidth, with low costs.

• Realizes carrier-class transport on mobile networks in aspects such as clock and

QoS.

• Inherits years of maintenance experience of carrier networks.

– Realizes evolution of carrier networks towards all-IP and achieves sharing of 90% 2G,

3G, and LTE sites.

• Realizes evolution towards all-IP through the MSTP equipment in large-scale

deployment and protects existing investment.

• What architecture should the MSTP products to be purchased have to support

evolution to all-IP?

• Integrates the PTN features on the traditional MSTP products to support smooth evolution of MSTP products.

Step 1 Replace the standby TDM cross-connect board with a dual-core cross-connect board. Then, switch the services from the active TDM cross-connect board to the dual-core cross-connect board.

Step 2 Replace the active TDM cross-connect board with a dual-core cross-connect board. Then, switch the services from the standby dual-core cross-connect board to the active dual-core cross-connect board. The switching time is less than 50 ms.

When configured with PTN service processing boards, the equipment can be used to build a PTN network without any impact on the existing TDM services.

1. After replacing the cross-connect boards, upgrade the software of all the boards housed on the NE to version R9C03.

2. The SCC boards of the OptiX OSN 3500 can be replaced or not. If they are replaced, the product specifications are different.

3. Replace the PIU boards with ones of large power consumption (optional).

New packet services raise new requirements on the transport network with respect to bandwidth utilization, service management, protection, and equipment maintenance. Hence, the traditional network has to be re-constructed for packet services.

For co-existence of new and old services, the MSTP equipment on the existing network should be upgraded to the MSTP+ equipment with dual planes. Then, the SDH services on the existing network are not affected and a better bearer can be provided to the new packet services.


If certain equipment on the existing network is not suitable for upgrade, the other equipment can be upgraded for hybrid networking with PTN products.

At the aggregation layer, the equipment can be upgraded to MSTP+ equipment and the capacity can be expanded by using 10GE boards. Then, the equipment can be networked with the OptiX PTN 3900 to build a 10GE ring network.

At the access layer, the OptiX OSN 1500 or OptiX Metro 1000 can be networked with the OptiX PTN 910/950/1900 to build a GE ring network, which is connected to the aggregation layer.

The T2000 can manage both the PTN and MSTP+ products.

Specifications of the PIUA Board

The PIUA board is not a new board for the OptiX OSN 3500

V100R009C03. From February 2008, the delivery switchover started. On

the existing network, 60% of the power boards are the PIUA boards.

To upgrade the OptiX OSN 3500 to MSTP+ equipment, the PIU board

must be replaced with the PIUA board.

Restrictions:Neither the PIU nor the PIUA supports remote identification. Hence, they

need to be identified on site.

Software Features of the OptiX OSN 1500/3500


Features of the Common Software

Product Feature DescriptionCommon Protection on the

packet planeSupports 1+1/1:1 LSP protection with the switching time less than 50 ms.

MPLS control plane The MPLS (MPLS-TP) control plane supports static configuration.

QOS The OptiX OSN 3500 supports MPLS-based DiffServ , H-QoS, and the ability to configure priorities based on tunnels.The OptiX OSN 1500 supports MPLS-based DiffServ.

MPLS OAM Checks connectivity of LSPs by performing connectivity verification (CV) and fast failure detection (FFD) and performs switching within 50 ms in case of a fault.

ETH-OAM Supports 802.1ag and 802.3ah (not supported by the OptiX OSN 1500).

Packet clock Supports synchronous Ethernet clock and IEEE 1588v2 packet clock.


Carrier-Class End-to-End Network-Level APS Protection(1+1/1:1 LSP Protection) ）

• The fault detection and protection switching are based on hardware. The OAM packets are inserted every 3.3 ms. A fault can be detected within 10 ms and the protection switching can be completed within 50 ms.

• The hardware-based OAM enables multiple LSPs to be switched within 50 ms.

H-QoS Based on Users and Services

• UNI side: The H-QoS controls small tunnels to ensure QoS for each user and each service.• NNI side: The H-QoS controls large tunnels according to the planning and provides QoS

similar to that of SDH.

Clock/Time Synchronization Solution

• The clock/time synchronization solutions are as follows:– IEEE 1588V2 clock, which is co-frequency and in-phase. All the nodes that the

IEEE 1588V2 clock signals traverse must support the IEEE 1588V2 clock.– Synchronous Ethernet clock, which is co-frequency and stable, and is similar to the

SDH clock. All the nodes that the clock signals traverse must support the synchronous Ethernet clock.

Appendix II: Usage Restrictions on Boards with Packet Features

• The ports on the PETF8/PEFS8 do not support the 10M rate or half-duplex mode.– The NE software suppresses such configuration.

• The following Ethernet ports do not support the function of setting or querying flow control:– IP1/IP2 ports on the PEG16– All ports on the PEX1– All ports on the PETF8– All ports on the PEGS2 and PEGS1– All ports on the PEFS8

• The preceding ports support RMON statistics only on good packets and errored packets.

• In the case of the PEGS1/PEGS2/PEFS8 , the load sharing algorithm does not support the source IP address.

• In MPLS service-carrying mode, the PEG16/PEX1 does not support transparent transmission of BPDUs.

Appendix III: New Maintenance Features of MSTP+ Equipment

• Currently, the MSTP equipment of version V100R009C03 does not support the fiber auto-

search function.

• The MSTP+ equipment does not support the function of uploading or downloading

configuration data to or from the NMS, or pre-configuration. Similar to the ASON features,

only the database upload/download function can be used for disaster tolerance.

• Multiple dynamic protocols are new for the packet features. Hence, in case of a warm

reset, the active and standby SCC boards are switched to reduce impacts on packet

services.

• To upgrade the equipment on the existing network to V100R009C03, which supports the

IEEE 1588 feature, by means of package loading, select proper package files. In addition,

the equipment of version V100R009C03 does not support the license control on the IEEE

1588 feature. Instead, you need to manually control the IEEE 1588 feature.
