摘　　要：为解决传统VPN扩展性差的问题,在ISP的城域网中,利用MPLS技术,设计与规划基于IP城域网的MPLS VPN模型,通过LSP隧道测试、路由跟踪测试等方法和理论分析,证明了基于IP城域网的MPLS VPN易于扩展,解决了传统覆盖型网络中普遍存在的扩展性N^2问题,降低了用户和ISP网络管理的复杂度。In order to deal with the worse extendibility of the traditional VPN, in ISP MAN, with MPLS techniques, MPLS VPN model based on IP MAN is designed and planned, through the ways and theoretical analysis such as LSP tunnel test and routing-following, the easy extendibility of MPLS VPN based on IP MAN is proven, and the problem has been solved that extendibility of N^2 exists widely in the traditional overlay-VPN, and the complication of the network management of users and ISP has been reduced.
