MPLS中一种快速检测路由环的方法

A Fast Routing Loop Detection Method in Multi-Protocol Label Switching

在多协议标记交换 (MPLS)中 ,如果出现路由环路将会严重影响网络的性能 .证明了在支持 VC合并的网络中路由环会导致流量的雪崩效应 ,因此在这种情形下需要尽快地检测出路由环 .提出了一种路由环检测方法 ,称之为 RMLD.它通过使用一种特殊的 RM信元可以在第二层上快速检测出路由环 .由于中间节点对 RM信元不需要添加或修改任何信息 ,因此

The routing loop will cause snowslide effect in VC merging capable network, so it must be detected as soon as possible in the case. A routing loop detection method called RMLD was proposed, which can quickly detect the routing loop in the second layer by using a kind of special RM cells. Because the middle nodes do not need to add or modify any information in the RM cells, RMLD has good expansibility and there is no cooperation problem.
