针对目前城域网差别化服务质量的部署现状，设计了基于Cisco网络实验环境并搭建BGP/MPLS VPN网络，部署MPLS DifferServ和DS-TE应用模型。通过对穿越城域网VPN的四种业务的QoS参数进行分析，结果表明在网络资源匮乏的情况下，DS-TE应用模型很好地提升了IP城域网差别化服务质量，DS-TE改善了在一条或一组LSP隧道为不同VPN业务、同一VPN不同业务以及VPN业务和非VPN业务之间的服务质量问题。

In view of the current deployment status of metropolitan area network differentiated quality of service the experimental environment based on Cisco network is designed,and the BGP/MPLS VPN network,MPLS DifferServ and DS-TE application models are build. Four businesses QoS parameters of VPN intracity networks are analyzed. The results show that under the lack of network resources,DS-TE application model enhances the IP metropolitan area network differentiated quality of service,and the DS-TE imoproves the problems of service quality of different VPN service,different business of a VPN,services between VPN and non-VPN in one or a combination of the LSP tunnel .
