基于RPR高生存性网络Layer2路由的研究

Study on routing algorithm of RPR-based high survivability network

基于RPR高生存性网络(环环相切、多环互连的网络拓扑结构),分析了该拓扑结构的特性。并在此基础上,提出了一种利用分层树状拓扑信息表和子网拓扑信息表实现的最少跳Layer2路由选择算法。通过网络仿真工具OPNET验证了该算法的可行性及其优越性,给出了仿真结果。

In this paper, we analyze a special network which has high survivability based on multi-ring topology structure. Basing on this special topology structure, we get a lest-hop routing algorithm by utilizing layered tree-liked topology message table and subnet topology message table. Using the network simulation sottware OPNET, we also validate the feasibility and superiority of the algorithm.
