一种面向生存性提升的光网络增长设计算法

摘要

The incremental design algorithms that make un2-cornected networks develop toward survivable topology are investigated,and a strategy called SBPP-TA which provides shared backup path on augmented topology is proposed.Through formulating Integer Linear Programming (ILP) model and simulation,numerical results show that,SBPP-TA improves the network survivability with little extra resources added into the network.%研究了使非2-连通的光网络向可生存结构升级演进的增长型设计策略,提出了通过在增广拓扑上为网络业务提供共享路径保护来确定网络增长规划方案的SBPP-TA机制.通过建立整数线性规划(ILP)模型并进行仿真,结果表明,SBPP-TA策略能在添加尽量少的网络资源的情况下有效提升网络的生存性.
