Method and system for analyzing the topology of a multiprotocol label switching(MPLS) virtual private network (VPN) network

摘要

In general, embodiments of the invention relates to a method for analyzing a topology of a multiprotocol label switching (MPLS)/Virtual Private Network (VPN) network. The method includes obtaining logical com-munication channel information for a plurality of virtual routing and forwarding (VRF) instances, wherein each of the plurality of VRF instances are located on one of a plurality of routers, wherein the logical communication channel information specifies a plurality of logical communication channels between the plurality of VRF instances, and wherein at least two VRF instances are located on one of the plurality of routers. The method further includes constructing an audit matrix representing the logical communication channel information, wherein the audit matrix specifies the topology of the MPLS/VPN network analyzing the audit matrix to obtain an analysis result, and presenting the analysis result.
