A Routing Algorithm for Traffic Engineering in MPLS Networks

A new routing algorithm,minimum competition routing algorithm,is proposed for MPLS traffic engineering.The algorithm targets to improve the utilization of network resources,and enable network to accept the route request as much as possible.The algorithm not only takes the impact of maximum-flow-zero-edge into account but also considers competition for bandwidth among all ingress-egress pairs in a MPLS network.Simulation results have shown that the minimum competition routing algorithm can accept more route requests than other three algorithms.
