光网络中一种部分SRLG分离路由方法

An algorithm of partial SRLG-disjoint diverse routing in optical network

利用SRLG失效对网络最大流的消减程度来评价SRLG重要性的方法,提出基于重要性的部分SRLG分离算法MIDR。仿真对比分析MIDR算法和保护路优先算法,MIDR算法使整个网络能为更多的业务提供服务,降低网络的阻塞率。

This paper proposes a heuristic method, called the Multiple Importance Diverse Routing （MIDR）, which can find two approximately SRLG-disjoint paths in WDM mesh networks. Comparisons are made between MIDR and the Active Path First （APF） algorithm. Simulation results show that MIDR can effectively reduce the required spare capacity and enhance the network resources utilization.
