UTILIZING CONSTRAINT OPTIMIZATION FOR EGRESS PEER ENGINEERING TO DETERMINE OPTIMIZED TRAFFIC PLANS AND TO IMPLEMENT AN OPTIMIZED TRAFFIC PLAN

A device receives network data associated with a network that includes a peer network with network devices interconnected by links, and receives constraints associated with determining traffic assignments for the network. The device determines traffic and costs associated with the network based on the network data, and determines traffic assignments based on the traffic and the costs associated with the network, the constraints, and a model for the constraints. The device determines tunnel use based on the traffic assignments, and determines peer link use based on the tunnel use. The device determines costs associated with the traffic assignments, the tunnel use, and the peer link use for the network, and generates traffic plans based on the traffic assignments, the tunnel use, the peer link use, and the costs. The device causes one of the traffic plans to be implemented in the network by the network devices and the links.
