摘　　要：分析了MPLS流量工程中重路由技术和保护切换恢复模型,结合IPv6特性,提出了基于优先级的重路由转发机制——优先级MPLS机制(P-MPLS).该机制为数据流设置不同的优先级,当工作路径发生故障时,将高优先级的数据流优先切换到保护路径上,从而使高优先级的数据流得到QoS保证.实验表明,P-MPLS降低了延迟和丢包率,提高了吞吐量.According to the analysis of the rerouting technology and the protection switching model for path recovery in MPLS Traffic Engineering,and the IPv6＇s properties, this paper propose a mechanism of rerouting and forwarding priority-based, Priority-MPLS（P-MPLS）. It can set different priority for data flow,when working link is fail data flows with high priority will be transferred to protective link first. So the data flow with high priority can get enough QoS. The simulation results show that P-MPLS can decrease delay and drop loss rate,and increase throughput.
