MPLS adaptive traffic engineering algorithm based on hops and delay

The advent of multiprotocol label switching(MPLS) allowed packets to be sent along explicit paths,an explicit routing mechanism,which put a true basis for traffic engineering. A MPLS adaptive traffic engineering algorithm based on hops and delay was presented. The algorithm distributed traffic among LSP according to hops and delay of each LSP. Therefore,congestion resulted from destination-based forwarding in traditional IP routers could be avoided and optimize network resource utilization. Simulation indicates that the algorithm work well in MPLS networks.
