Abstract
Systems and techniques for fault analysis in a data communication system. A fault analysis console in a provider network serving one or more customer networks responds to a reported loss of connectivity in the customer network by analyzing traffic statistics for a router serving the customer network. If traffic statistics indicate network functionality, border gateway protocol status is evaluated for logical channels being served by the router. Test communications are performed for customer edge router addresses for the logical channels and border gateway protocol status is evaluated for each customer edge router address. Test communications are then performed from a local provider edge router to each remote customer edge router being served.
