The present disclosure generally discloses improvements in computer performance in communication networks, which may include improvements in computer performance in supporting discovery of ingress provider edge (PE) devices in a communication network using egress peer engineering (EPE) and software defined networking (SDN). The ingress PE devices of a network may have peering relationships with an egress peer link of an egress peer node of the network. The ingress PE devices may be discovered by identifying a set of traffic flows on an egress peer link of an egress peer node, identifying a set of ingress PE devices that have peering relationships with the egress peer node, determining bandwidth usage information, selecting, from the set of ingress PE devices based on the bandwidth usage information, a set of selected ingress PE devices, and initiating a management action for at least one of the selected ingress PE devices.

Discovery of ingress provider edge devices in egress peering networks

The invention is directed to providing a method and system for automatically determining a root cause of a failure in a packet switching telecommunications network using IP/MPLS protocols and having Virtual Private Network (VPN) services such as VLL, VPLS, VPRN.

Auto VPN troubleshooting

The invention is directed to configuring services in a packet switching network. Embodiments of the invention group existing service policies configured on network routers into policy groups, thereby enabling better management of service policies and policy overrides. This functionality can be useful for identifying redundant policies that may be eliminated by reconfiguring one or more of the network routers to reduce the overall network-wide number of policies, as well as provisioning new services in a manner that efficiently uses existing policies.
