A VRF/RT-based Algorithm for Discovering VPN Topologies in BGP/MPLS IP VPNs
BGP/MPLS IP VPNs defined in RFC4364 allow service providers to use their IP backbone to provide VPN(Virtual Private Network) services. Currently most of service providers track 4364 VPN topologies either manually or by using a provisioning database. The goal of our algorithm is to discover VPN topologies as a composition of atomic and molecular components. Our algorithm uses a matrix model to represent a complex VPN. The algorithm decomposes this matrix to identify all the atomic components, and finally to construct molecular components from the atomic components. By using our algorithms service providers can automatically discover VPN topologies that have already been configured using the current network configuration information about VRF (VPN Routing and Forwarding)and RT (Route Target).
