摘　　要：提出了一种基于分布式点到点延迟受限路由的DCLC-K算法,解决了分布式QoS路由算法运行过程中历史信息最大利用问题,仿真表明,该算法在不要求中间路由器记录寻路信息和适中的消息复杂性基础上取得了良好的代价性能.A distributed QoS heuristic algorithm based on unicast routing by applying the concept of the cost and delaybounded is proposed. This algorithm can generate the routing path that is subject to a suboptimal network cost under the condition of delay constraint, with a relatively low message complexity. And it needs no information stored in media router during the path setup. Simulations have been done to show the efficiency of the algorithm proposed.
