METHOD, APPRATUS, AND SYSTEM FOR CAPTURING TRAFFIC STATISTICS BETWEEN TWO SITES OF MPLS BASED VPN

摘要

A technique for effectively capturing site-to-site traffic statistic without significantly affecting the performance of a router in an MPLS-VPN service network is disclosed. In one example embodiment, this is accomplished by computing source PE IP and source PE interface from each flow record received at a destination PE router to identify an associated source VPN site.
