基于Multi-agent的P2P流媒体技术的研究

基于P2P的流媒体技术很好的解决了传统流媒体带宽不足的问题,从而得到广泛研究;但是由于流媒体严格的时序性要求,使得P2P流媒体技术的使用存在瓶颈.本文提出一种基于Multi-Agent的P2P流媒体技术应用模型,利用多Agent的移动性和协作性,在各个节点构建状态信息树,通过对节点状态信息树的更新和维护,可以有效的解决Peer服务节点的搜索定位以及Peer节点离开或失效处理等问题.文章首先对目前各种流媒体技术的研究现状进行阐述;接着提出基于Multi-Agent的P2P流媒体技术的应用模型,着重介绍节点状态信息树的构建过程和更新过程;最后指出其发展前景和面临的挑战.

Research on Technology for Streaming Media over P2P Network Based on Multi-agent

P2P media streaming technology can utilize bandwidth resource of host nodes enough to provide service without changing the current deployment of Internet and be searched widely.But due to the service of Peer node is hard to match stringent timing requirement,which is the bottleneck of P2P media streaming technology.Technology for Streaming Media over P2P Network based on Multi-agent is proposed,for solving finding of peer nodes and detecting of disabled peer nodes.Further more,node-condition-information-tree is introduced,and its updating and maintaining can perfect services of Peer node.Firstly,the development of distributing streaming media content;then the model of streaming media P2P based on Multi-Agent;finally,node-condition-information-tree is emphasized;then its foreground.
