摘　　要：为了适应多层次网络发展的需要,在讨论WDM光层生存性机制的基础上,针对多层网络联合的生存性机制进行了仔细的分析,提出了一种多层协调的实现办法,并讨论了多层空闲资源设计中的共享问题。This paper presents the fundamental principles of network protection and restoration in optical layer, and detailecUy analyses on the survivability in multi - layer networks according to the need for the development of multi - layer networks. With regard to multilayer survivability, one implementation method for the coordination between in individual network layers is proposed and sharing of spare capacity is also introduced.

关 键 词：生存性 多层网络 空闲资源
