摘　　要：MPLS流量工程通过优化IP网络资源的使用以提高网络性能,同时结合约束路由和面向连接的标记交换路径提供了端到端的QoS保障。在网络上层,DiffServ和MPLS相结合,DiffServ将业务分类、整形、聚合,MPLS再将处理过的数据转换成不同的标签进行转发。在网络底层,MPLS与WDM光网络技术相结合,从而实现更快、更智能的数据传送。MPLS traffic engineering can improve IP network performance through usage optimization of network resource and provide end to end QoS provision through combination Constraint Based Routing and connection oriented label switch path.On the top of the network,combine DiffServ with MPLS,service will be classified, repaired and assembled by DiffServ;MPLS will turn processed data into different label and forward.At the bottom layer,MPLS and WDM are combined with each other directly to make data transmission more rapid and more intellectual.
