WDM环网保护方式的性能评价及设计原则

Performance Evaluation and Principles of Design for WDM Ring Pro tection Networks

WDM环网以其灵活性、管理简单及生存性好等特点受到普遍重视。文章首先讨论了在进行WDM环网保护方式的设计中需注意的几个问题,并对目前可能有的几种WDM环保护方式作详细性能分析,并从不同得角度作了比较,从中得出了一些有益的结论。在此基础上,给出了进行WDM环网保护设计中应遵循的一些原则。所得出的结论对今后WDM环网保护方式的研究与设计都有一定的借鉴和帮助。

WDM ring network is gaining acceptance as its flexibility,simple management and well survivability.This pa-per looks at several kinds of WDM ring protection networks and some problems which must pay attention to,and then analysis and compares their performance.Finally,It gives some principles of design the WDM ring protection networks.The conclusion will be helpful to the research and design for WDM ring protection networks.
