摘　　要：随着网格状网拓扑在新一代光传送网中的应用,基于网格状网的光传送网生存性成为一个值得研究的课题。从光层保护入手,首先分析了网格状网生存性的主要特征;接着对网格状网的保护与恢复进行了总结与归纳,并介绍了不同保护机制的应用特点;最后对网格状网中多层联合保护策略进行了较为深入的探讨。With the application of mesh network topology in the next generation optical transport network,the survivability of mesh-based next generation optical transport network will be a desirable project. This paper starts with the protection of optical layer,analyzes the main characters of mesh network survivability firstly,then concludes and summarizes the protection and restoration of mesh network,and introduces the application characters of different protection mechanisms. At last,the authors discuss the strategies of multi-layer protection deeply.
