| 摘 要： | 概述了MPLS的流量工程和故障恢复机制。在区分服务网络环境中,描述了一种基于集中模型的多故障的重路由算法。采用以优先级属性划分LSP的策略,将带宽作为主要需求参数,满足了不同LSP的QoS要求。其实现是基于MPLS流量工程的约束路由的最优化方程。模拟示例分析验证了算法的可行性和优越性。

| Abstract: | The TE and recovery model of MPLS is generally presented to introduce the corresponding problems.Under the Diff-Serv environment,an algorithm based on multi-failures model and centralized implementation mode is described for rerouting.It focuses on the bandwidth requirements for each LSPs.In order to meet the different QoS requirements of LSPs,it divides the LSPs according to the set-up priority and holding priority of LSPs.Furthermore,it is implemented by an optimization equation based on constraint route of MPLS TE.At last,the simulation validates the feasibility and the advantage. |
