摘　　要：多种不同层次技术的融合是现代通信网络的一大特点,同时也它带来了多层网络中故障恢复机制的协调问题。首先对多层网络中涉及到的各种生存性问题进行了概述,然后在IP/optical网络结构下,详细介绍分析了多层网络中的各种生存性策略。最后,给出了在多层网络中如何选择相应的生存性策略的指导方针。The integration of different layer technologies is one of the features of transport network. Themulti-layer network also introduces the problem about coordination of the individual layer restoration mechanics. In this paper, firstly the survivability problems in multi-layer network are discussed. Then some multi-layer survivability policies are analyzed in the IP/optical network. At last, the guidance for the selection of multi-layer survivability policies is concluded.
