摘　　要：提出了一种基于跳数和时延的 MPLS 自适应流量工程算法,该算法根据 LSP 的跳数和时延来进行流量分配,从而减少由传统路由算法而引起的网络拥塞,优化网络资源的利用。仿真结果表明,该算法简单易行,性能良好。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.
