SDH自愈环的路由算法研究

本文分析了四纤双向共享保护环的几种业务路由算法，对各种算法所需的环路容量配置进行了计算机的随机统计模拟，基于上述模拟结果，讨论了用户接入网、局间中继网等网络所具有的不同业务分布模型与路由算法的关系，探讨了根据网络自身的业务特点选择业务路由算法的方法

Study of Route Algorithm for SDH Self Healing Ring

A network architecture and several route algorithms on 4fiber bi directional self healing ring (BSHR/4) have been analysed in this paper. Comparations of required capacity of BSHR/r related to the algorithms are made with the results obtained from the computer simulations. According to the result above, the relation between traffic features and route algorithms about access network and interoffice network is discussed, issues on rout algorithm choices of network are presented also.
