| 摘 要： | 在GMPLS光网络中,为了在故障定位时减少定位数障据链路故障的信令开销,避免不必要的网络资源浪费,降低网络资源的阻塞率,提出了一种分布式多层故障定位方法。该方法在现有的单层故障定位方案的基础上,通过双向数据链路故障通知的方法,避免了一些不必要的故障相关操作,减少了网络节点的负担,提高了网络资源的利用率。

| Abstract: | In GMPLS optical network,in order to reduce the overhead of positioning data link fault signaling,avoid unnecessary waste of network resources,reduce the blocking rate of network resources in the fault localization,a distributed multi-layer fault localization method is proposed.This method,by he method of two-way data link failure notification,avoid unnecessary fault-related operations,reduce the burden on the network nodes and improve the utilization of network resources on the basis of the existing single-fault location scheme. |
