摘要： 传统的多协议标签交换(MPLS)快速重路由故障恢复算法存在报文延迟、失序、故障修复时间过长等问题。为此，提出一种基于MPLS的快速重路由故障恢复综合模型，对LDP消息进行扩展、使用全局恢复机制和局部恢复机制相结合的综合策略，采用新型临时路径计算方法。仿真结果证明，该故障恢复综合模型可以降低丢包率，缩短故障恢复时间。

Abstract: The problems of packet delay, disorder and long recover time are widespread in traditional Multi-protocol Label Switching(MPLS) fast re-routing fault-recovery model. In order to solve the problems, a fast re-router fault-recovery synthetic model based on MPLS through expanding the MPLS message is presented. In this model, the LDP message is expanded, combined with global strategy and local strategy, and a new method to establish temporary path is put forward. The conclusion that this multiple model shows better performance on reducing fault-recover time is proved by OPNET network simulation.
