摘　　要：针对QoS约束多播路由问题,提出了一种基于Agent的分布式QoS多播路由算法AQRA(Agent-based Distributed QoS Multicast Routing Algorithm)。算法利用不同类型Agent之间的通信协作,寻求满足QoS约束要求的多播路由;在获得最优路径的同时可有效避免回路的产生,并且通过灵活的路由切换和锁定机制,保证了路由连接的成功建立。实验结果表明AQRA是一种正确、有效的QoS组播路由算法。In accordance with multiple constrained QoS muhicast routing problem, a new algorithm AQRA （ Agent-based Distributed QoS Multieast Routing Algorithm） was proposed based on Agent. AQRA took advantage of the cooperation of different Agent groups to find the optimum muttieast routing that satisfied the QoS constraint. AQRA exchanged and transmitted routing information to obtain local optimum route and avoid cycle during the Agent meeting. The flexible routing switching and locking guaranteed a successful routing connection. The experimental results indicated the feasibility and efficiency of AQRA.
