摘要

本文提出了一种新的启发式算法，称为流量恢复时间约束共享子路径保护(TC_SSPP)，以提供共享风险-链路-组(SRLG) WDM网络的生存性。TC_SSPP通过合理设置各链路的时延参数，并使用延迟约束最短路径算法(DCSPA)计算备份子路径，可以有效保证连接请求的流量恢复时间。仿真结果表明，TC_SSPP算法优于传统算法。

Shared Sub-Path Protection Algorithm with Recovery Time Constraint in WDM Networks

This paper proposes a new heuristic algorithm called Traffic recovery time Constrained Shared Sub-Path Protection (TC_SSPP) to provide survivability in WDM networks with Shared-Risk-Link-Group (SRLG). By properly setting the delay parameter of each link and running the Delay Constrained Shortest Path Algorithm (DCSPA) to compute the backup sub-paths, TC_SSPP can effectively guarantee the traffic recovery time for connection requests. Simulation results show that TC_SSPP outperforms the traditional algorithms.
