Faults and status in virtual private networks

摘要

A method embodiment for determining status of a private virtual network is disclosed. The method comprising classifying reachability faults of a virtual routing address into a plurality of first levels; classifying infrastructure faults of the virtual routing address into a plurality of second levels; and determining the status of the private virtual network based on one or a combination of the plurality of first and second levels of the plurality of virtual routing addresses. The private virtual network is part of a computing network including a provider network providing service to a plurality of virtual private networks.
