摘要

随着波分复用（WDM）技术的飞速发展

光网络的生存性要求也越来越高

文章阐述了光网络中通用的几种保护方法

给出了这几种保护方法的特点及使用范围

并且就资源利用率、造价、倒换时间、对节点的要求和对网络拓扑的要求这几方面做了比较和分析。最后得出在不同的网络

不同的生存性要求和不同的负载的情况下应采取不同的保护恢复方法。

Abstract

With the rapid development of WDM technology

the requirements of survivability of optical networks are increasing more and more. Some protection methods are given in this paper

and their features and applications field are analyzed too. In addition

comparison and analyses of these methods are given

which include the resource utilization

cost

the time of protection

the requirements of node and network topology. Conclusion can be drawn that different protection methods should be adopted according to different networks and survivability requirements.
