摘　　要：首先介绍了几种按照不同标准划分的WDM网络光层保护方法,然后提出了三种实现光层保护的新算法,对它们的内容和性能做了详细描述。按照提出的算法所求得的解,可以为WDM网络提供新的光层保护方式。Today,failure protection is gaining more and more significance.This paper present three new protection methods operated on optical layer in WDM networks and aimed to deal with the failure path rather than the single failure link. Algorithm I is an ILP(Integer Linear Programs), II and III, heuristic methods. In addition , an example solved by this three new methods is also shown.

关 键 词：光层保护 WDM 生存性 保护算法
