Product Details

Overview

ASON (namely, Automatically Switched Optical Network), means new-generation optical network, also called intelligent optical network. WSON specially refers to the control plane technology based on wavelength switch; while WASON in this document represents WDM/OTN control plane technology based on wavelength/sub-wavelength switch.

ZXUCP A200 is the WASON software system developed by ZTE on WDM/OTN platform with such functions as automatic routing, automatic discovery of resources and network topology, automatic service creation, fast service rerouting and SLA. It is applicable on edge layer of large MAN, metro backbone layer and national & regional backbone network.

ZXUCP A200 supports the following intelligent WDM products:

l ZXMP M820

l ZXWM M920

l ZXONE 8000

l ZXONE 9700

Features

Fast Automatic Discovery of Network Topology

With standard OSPF-TE protocol, ZXUCP A200 disperses and collects network information to automatically generate route information of the control plane, and disperses and collects network service link information to automatically discover network resource topology information. In this way, ZXUCP A200 achieves fast automatic discovery of network topology.

Powerful Automatic Discovery and Management of Network Resource

ZXUCP A200 uses standard LMP protocol to automatically discover and manage network control channel, automatically discover network link resource, verify & manage its connectivity and consistency.

The resource granules for automatic discovery and management include:

l Wavelength (OCh, 10G,40G,100G)

l Subwavelength (ODUk, k=0,1,2,2e,3,4)

Fast End-to-End Service Configuration

ZXUCP A200 adopts standard RSVP-TE protocol to fulfill fast ETE service configuration. The service supports SPC (soft permanent connection) launched by Management Plane (MP).

In service creation, it supports priority policies such as minimal price, minimal hops, load balance, shortest path and route constraint to select the optimal service path. In service deployment and operation, it can dynamically modify connection attributes, monitor the real-time run status, and reroute to rapidly restore faulty service. It also supports

automatic service deletion and complete release of occupied resources.

In the process of service connection path creation, it can automatically select the optimal service path and dynamically adjust the performance based on WDM optical-layer physical features by collecting and computing optical impairment parameters including OSNR, dispersion and PMD.

SLA

ZXUCP A200 can provide services of different service levels as required by the customers to resist multi-point faults in the network system and provide more stable and reliable protection. For example, when using diamond-level permanent 1+1 protection mode, the service protection switchover time can be kept less than 50ms in case the fiber is broken. SLA, Service Level Agreement, divides the services to different levels from the aspect of service protection, as shown in the table 1.

Standard Technology and Open Platform

Standard protocol support: It uses standard GMPLS protocol family for CP protocol stack, OSPF-TE for route protocol, RSVP-TE for signaling protocol and LMP for resource management.

Open interface scheme: Its standard I-NNI, E-NNI and UNI can interconnect the equipment from other vendors.

Good scalability: The core is independent and the information model is irrelative to specific equipment and vendor, so it is easy to be expanded.

Distributed structure and load balance: Configured in the distributed network node, CP employs independent high-performance CPU unit to rapidly control Transmission Plane (TP) and efficiently manage network and equipment.

Flexible Equipment Upgrade

ZXUCP A200 can be configured on the hardware platform of ZTE’s M820/M920, ZXONE 8000/9700 iOTN products. The iOTN system can be upgraded to WASON function flexibly by adding WASON software.

High Operability and Maintainability

With easy operation and rapid response, ZXUCP A200 CP and NMS can work together to bring excellent experience to the customer in WDM/OTN system running and maintenance.
