【摘要】 分析了MPLS区分服务和流量工程这两种技术;由于在一些应用情景下,需要使流量工程能够感知流量的类型,因此引入了MPLS感知区分服务的流量工程的方案,来建立基于类的流量中继。着重论述了该解决方案的各个方面,包括路径的计算、建立路径的信令、带宽约束模型等。更多还原

【Abstract】 MPLS diffServ and traffic engineering(TE) are the two technologies used for providing QoS in MPLS network,which are analyzed.Some of application scenarios are presented that can not be solved using diffServ or TE alone,MPLS-TE must operates at the aggregate level across all the diffServ classes of service.So MPLS diffServ-aware traffic engineering is developed to build TE trunk on a per class base.All sides of MPLS diffServ-aware traffic engineering solution are focused on,including application scenarios,path computation,path signaling,bandwidth constraint models and so on.更多还原
