摘　　要：研究了MPLS网络的故障管理。MPLS非光网络的数据平面和控制平面共享传输媒质,而光网络中数据平面和控制平面并非紧密地结合在一起,甚至不一定具有相同的拓扑,这就导致了两种网络在故障管理时存在很大差异。分析了MPLS非光网络与光网络的故障管理的区别,为MPLS非光网络设计并实现了一种LDP会话重建方案。The research of fault management in MPLS networks was focused on.In non-optical MPLS networks,the control plane messages and the data plane packets shared the same transmission medium.In contrast,the data and control plane were not so tightly coupled in optical MPLS networks.In fact,they did not necessarily even share the same topology.The difference between the fault management in non-optical MPLS networks and in optical MPLS networks was analyzed and researched.Fur- thermore,a recovery scheme of LDP session for non-optical MPLS networks was also designed and realized.
