摘　　要：针对网络质量控制问题,提出一种基于Agent的QoS组播路由算法。方法采用一组协同工作的Agent搜索网络,寻找满足QoS请求的路径,并对选定路径进行资源预留。优点在于Agent选路由具有一定的灵活性与适应性,路由器本身不需要具有QoS路由功能,不需要维持专门的QoS路由表,只需要提供Agent的运行环境和相关数据结构并进行仿真。仿真实验结果表明算法不仅具有较好的性能,并且不需要专门的资源预留协议,不必对现有模块进行大的改动就可以同时支持数据实时投递。This paper presents an Agent-based QoS muhicast routing algorithm. The method used a set of collab- orative work Agent network, found the path to meet the QoS request, and selected resource reservation path. Its ad- vantage is that the election Routing Agent is of a certain degree of flexibility and adaptability, the touters themselves do not need to have QoS routing functions, and QoS does not need to maintain separate routing tables but only need to provide Agent operating environment and associated data structure. Finally, we carried out an experimental simula- tion. The simulation results show that the algorithm has good performance, the algorithm and resource reservation calculation does not need a dedicated resource reservation protocol, and exchange nodes do not have to safeguard the o- verall state of infommtion and the existing modules do not need to been changed a lot to simultaneously support the best data and real-time data delivery.
