在虚拟专用路由网络(VPRN)的实现中,主干网的配置相对复杂,针对这一情况,分析了VPRN集成的约束条件和实现,使得在满足VPRN内部的连接和外部非关联VPRN之间相互独立的情况下更好地实现VPRN的集成。实现集成的目的是为了基于公共基础设施上的VPRN在满足低消耗和高性能的情况下容纳更多的用户,也可以实现不同用户参与不同的VPRN来达到不同的目的。
The configuration of the backbone for VPRN is fairly complex. An analysis of VPRN integrity constraints and the implementation are presented. It can implement VPRN integrity correctly with the satisfaction ofVPRN intra-connection and isolation of disjoint VPRNs. The purpose is to make VPRN contain more users based on public infrastructure in lower cost and higher performance. It also can make different user join different VPRN to reach different purposes.
