摘　　要：在网络中实施业务量工程非常重要,其目的是使网络中的资源利用更加平衡。据此提出了一种动态路由算法,引入“网络负载平衡度”的概念,用来描述网络中各条链路上的剩余带宽可用率相对于其平均值的偏离程度,并作为实施路由选择的一个关键性指标。仿真结果表明,相对于传统的最短路径优先路由算法,当网络重载工作时,该算法可以增加网络吞吐量,延缓阻塞的发生。Traffic Engineering has become an indispensable function in many large networks.A major goal of Traffic En-gineering is to facilitate efficient and reliable network operations while simultaneously optimizing network resource uti-lization.To meet the traffic engineering goals,a new dynamic routing algorithm is proposed.The algorithm specifies a pa-rameter named network load-balanced degree,which presents the deviation to the average utilization of the residual bandwidths on each link in the network.The simulations show that the algorithm earns more throughput than traditional Shortest Path First routing algorithm when network in heavy load situation.

关 键 词：业务量工程 路由算法 剩余带宽 负载平衡
