摘　　要：光网络中的圈状结构具有保护速度快、资源利用率高、构造和算法相对简单等特点,特别适用于光网络生存性技术的实施。首先介绍了圈的概念及相关定理,分析了现有基于圈状结构的光网络生存性技术,最后阐述了圈状结构生存性技术存在的问题及解决方法。The cyclic structures of optical communication is characterized by fast high utilization of resources, simpler configuration and algorithm, etc. , and is usef the survivability technologies in optical network. The definition and the theorems protection, ul to realize cycle are analyzed. Several survivability methods of the cyclic structures are presented. The issues that should be considered when we design the cyclic structures are introduced finally.
