MPLS VPN差别化服务的实现技术模型及应用

Implementation of MPLS VPN differentiated service technology and its application

为了满足互联网接入业务的服务质量需求,改变缺乏区分服务BGP/MPLS VPN网络的Qos的现状,提出了MPLS VPN网络的差别化服务应用模型,引入区分服务感知的流量工程(DS-TE)应用模型,通过MPLS Differ Serv模型在PE端的应用和DS-TE模型实现最小带宽的保证,从而实现高优先级业务服务质量的同时实现了优化网络资源的目的。

In order to meet the needs of the service quality of Internet access business,change the status of lack of Diff Serv BGP / MPLS VPN network Qos,this paper puts forward the differenced service application model of MPLS VPN network, introduced Diff Serv aware traffic engineering（ DS-TE）application model,through the implementation of minimum bandwidth application and DS-TE model MPLS Differ Serv model in the PE end of the guarantee,it achieves the high priority service,quality of service,at the same time it realizes the optimization of cyber source.
