面向共享风险链路组故障恢复的多路径路由生成算法
摘要
为了在IP层恢复网络共享风险链路组(SRLG)故障
提出一种基于改进人工蜂群算法的网络多路径路由生成算法。针对SRLG故障特点建立多路径路由生成模型
最后通过改进人工蜂群算法求解。仿真验证该方法不仅可以生成满足SRLG约束的备用路径
还可以增强故障恢复能力、降低算法复杂度、缩短重路由的平均路径长度。
Abstract
Aiming at recovering from network shared risk link group( SRLG) failures in IP layer
a generation algorithm of network multi-path routing is proposed based on modified artificial bee colony algorithm. A multi-path routing generation model focusing on SRLG failure characteristic is created and modified artificial bee colony algorithm is used to solve it. Simulation results show that this method can not only generate backup path satisfied to SRLG constraints
but also can strengthen failure recovery ability
reduce algorithm complexity and shorten average length of rerouting path.
