摘　　要：综合考虑用户服务质量QoS需求和网络提供方收益的单播路由算法.给定用户请求类别和收费原则,通过建立网络提供方收益模型来确定针对每一类请求的概率收益.在此基础上,利用模糊塔,求出两网络节点之间既满足用户服务质量需求又试图最大化网络提供方概率收益的路由。仿真结果表明,算法是可行的和有效的。With both user QoS (Quality of Service) requirement and network provider profit being considered,a QoS unicast routing algorithm was proposed. Given the class of the user request and charging principle,the network provider probability profit was determined by building a profit model. Based on that model,the specific route between two network nodes was found,satisfying the user QoS requirement and attempting to maximize network provider probability profit by using fuzzy tower. Simulation results have shown that the proposed algorithm is both feasible and effective.
