摘　　要：未来传输网络中,不同的网络技术(如IP、SDH和WDM技术)的融合需要不同网络层次之间进行有效地配合,特别是网络生存性领域更是如此。首先对多层网络生存性机制的框架以及在多层网络环境下实现网络生存性的技术进行了概述,同时以IP over WDM为例,说明了这些方法的应用方式。The integration of different technologies such as IP, SDH and WDM in future multi-layer transport networks requires a better coordination between the individual network layers, especially in the area of network survivability. This article takes a look at the framework of survivability schemes in multi-layer networks, and the techniques used to achieve survivability in such transport networks. Also we take IP over WDM as an example to show how these multiple recovery schemes are coordinated.

关 键 词：多层网络 生存性 IPOVERWDM
