Abstract:
1. A method for capturing site-to-site traffic data in Multiprotocol Label Switching-Virtual Private Network (MPLS-VPN) based networks comprising: computing a source Provider Edge (PE) IP address and a source PE interface name for each flow record captured at a destination PE router, wherein each flow record includes a traffic record of IP packets traversing from a source PE router to the destination PE router in the MPLS-VPN network, and wherein computing the source PE IP address and source PE interface name comprises: identifying a source VPN site by querying the VPN provisioning system database and the associated PE router based on the computed source PE IP address and the source PE interface name for each flow record traversing from the source PE router to the destination PE router, and wherein the source VPN site accesses the MPLS-VPN network through the source PE router.
