摘　　要：随着mesh拓扑在新一代光传送网中的应用,基于mesh的光传送网生存性将成为一个值得研究的课题。本文从光层生存入手,首先分析了mesh生存性的主要特征;接着对mesh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mesh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 topology in the next generation optical transport network.,the survivabi-lity mesh-based of next generation optical transport network will be a desirable project. This paper starts with the survivability of optical layer, analyzes the main pro-tection characters of mesh firstly, then concludes and su-mmarizes the protection and restoration of mesh, and in-troduces the application character of themselves; At last, the authors discuss of the strategies of multi-layer protection and restoration.
