摘　　要：研究MPLS网络中的重路由故障恢复机制,提出一种新的计算备用路径的方法,将备用路径的计算分为预处理和在线计算2个过程,给出一种基于基本回路的重路由故障恢复机制(FC-R)。仿真分析表明,FC-R恢复时间较短,可以对抗节点故障或链路故障,大大缩短在线计算时间,减轻节点负担,能够得到性能较优的备用路径,进一步节省网络资源。On the basis of analysis of rerouting scheme for MPLS network, a new method of computing backup path is advised, where the computation of backup path is divided into two steps： pro-processing and on-line processing. Based on the new method, a Fundamental Circuit Rerouting（FC-R） scheme is proposed. Simulation results and analysis Show that FC-R has many advantages as follows shortening recovery time, increasing resource utilization, supporting link failure and node failure, and saving the time in on-line computing.
