摘　　要：分析传统MPLS故障恢复机制的不足,提出一种新的MPLS故障恢复模型。该模型采用三种备份路径来减少丢包率。在传统MPLS故障恢复机制不考虑QoS的情况下,该模型将Diffserv、TE(Traffic Engineering)及MPLS三者相结合,来实现Diffserv网络中的QoS。仿真试验和结果分析证明了该模型的可行性和有效性。This paper analyses the inadequacy of restoration mechanism of traditional MPLS and proposes a new model for MPLS fault recovery.This model uses three types of backup path to reduce packet loss rate.In circumstance of when the traditional MPLS restoration mechanism doesn＇t consider the QoS of network,the model realises QoS in Diffserv network by combining Diffserv,TE and MPLS technologies.Simulation experiment results analyses prove the feasibility and effectiveness of the model.
