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。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.
