4 MSTP传送网网络管理需求
4.1 基于SDH的MSTP业务网络模型
基于SDH的多业务传送节点(MSTP)是指基于SDH平台,同时实现TDM、ATM、以太网等业务的接入、处理和传送,提供统一网管的多业务节点。MSTP传送网与SDH传送网之间的主要区别在于前者能够提供更完善的数据业务(如以太网、ATM)的传输服务。
MSTP网络提供数据业务的网络模型主要分为两部分:边缘到边缘的以太网、ATM业务连接(即:UNI-N到UNI-N)和两端的接入链路(即:UNIC与UNI-N之间),如图1所示。其中边缘到边缘的以太网、ATM业务连接是MSTP网络提供的传送通道部分。端到端业务连接是指UNI-C到UNI-C之间的业务连接,业务连接与管理实体之间的关系见表1。
