摘要

保护倒换时间是评估网状波分复用网络保护方法性能的一项重要指标

本文就专门路径保护、共享路径保护以及共享链路保护三种保护方法

分别建立了各自对应的保护倒换时间计算模型

然后分析了影响保护倒换时间的主要因素

并在此基础上提出了相应的优化策略和解决方案

本文结果对于正确选择保护方法具有一定的参考价值.

Abstract

Protection Switching Time (PST) is an important metric on evaluating the performances of protection methods in mesh WDM network.This paper provides three types of arithmetic model of PST for dedicated-path protection

shared-path protection and shared-link protection separately.And then some optimal strategies and available solutions are provided on the base of analyzing several principal issues affecting PST.Result of this paper has some reference value for correctly choosing protection method.
