摘　　要：介绍了流量工程在Internet中的作用,以及流量工程中静态算法的地位.分析了当前静态路由算法研究现状并指出存在的缺点,由此提出一种新的可应用于流量工程的静态路由算法.该算法通过分析各服务质量需求,在算法运算过程中分阶段运用主次目标函数处理,从而满足流量工程中的服务质量需求,使网络资源得到充分利用.最后以编程仿真和理论推导两种方法论证了该算法的有效性、优越性.This article aims at the traffic engineering in the Internet and the station of static algorithm in traffic engineering.The present situation of static routing and its limitation are demonstrated and a new static routing algorithm based on constraintbased routing is given.With analyzing each requirement of QS (Quality of Service),we use the united object functions during the different phases.By this way,each requirement of QS in traffic engineering is fulfilled and the resource of networks is fully used.Finally we prove that the algorithm is feasible and preferable by computer simulation and theoretical deduction.
