| 摘 要： | 传统的MPLS快速重路由技术在面对网络多故障的情况时有许多不足之处,为了更好的解决问题,提出一种新的MPLS快速重路由多故障恢复算法.算法采用Detour路径保护方式,对有不同备份路径经过的链路上的预留带宽资源进行共享管理,并为工作路径建立主、从备份路径.仿真实验结果显示,该算法能够有效减少备份路径上预留带宽资源消耗,对出现多故障的网络进行快速恢复.

| Abstract: | As traditional MPLS fast reroute technology exist much weakness of dealing with multi-failure,a novel MPLS fast reroute multi-failure recovery algorithm is presented to solve the problem better.The algorithm adopts Detour path protection manner,allows reserved bandwidth resource sharing among backup links of the different service paths,and sets up primary and secondary backup paths for the service paths.The simulation experiment result shows that the algorithm can reduce the consumption of the backup paths’ reserved bandwidth resource and recover the network fast when multi-failure happens. |
