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.

The invention is directed to providing a centralized synchronization method for redundant network elements and is particularly advantageous to routers providing network address translation (NAT) services requiring static port forwarding provisioning. Synchronization is provided by a network management system which can handle one or more backup routers or other network elements using a control protocol different from the control protocol used by the active router.
