摘要
文章通过对MPLS消息的扩展,提出了一种新的Bridge消息,并据此提出了一种新的基于MPLS的快速重路由模型———Bridge模型,该模型充分利用了主路径与备份路径之间起桥梁作用的链路,备份路径尽量减少了反向传送业务流的机会,使得业务流重路由沿着较短路径进行,避免Haskin模型大量的分组失序和较大的延时,同时避免了Makam模型中大量的数据包的丢失。NS2仿真结果表明Bridge模型具有较优的快速重路由性能。
A new bridge message through expanding the MPLS messages was proposed. And according to this a novel quickly re-router model --bridge model based on MPLS is presented, which make use of links between working path and backup path (reduced the chance of reversed traffic flow) as bridge to makes the traffic in shorter path and avoid grouping disorder and the longer delay caused by Haskin model. At the same time, more loss of data packages Makam model caused was avoided. Better performance of quick re-routing of a bridge model was shown through simulation results of NS2.
