摘要
设计了基于邻居优选的P2P流媒体传输系统的体系结构,研究了流媒体数据的采集、分割和传输技术;根据各节点的连接质量指标进行邻居优选,动态选择优良邻居并淘汰薄弱邻居,有效降低了服务端的负载,增强了流媒体数据传输的实时性和可靠性;最后,实现了基于邻居优选的P2P流媒体传输的原型系统。实验表明,基于邻居优选的方案是高效、可行的。
This paper introduced the structure of P2P stream mediatransmission system based on neighboring optimum selection,studied the acquisition,breaking up and transmission technology of stream mediadataand made the neighboring optimum selection according to the different indices of joint quality of nodes.Also,it designed the P2P stream mediatransmission system framework based on the neighboring optimum selection.Moreover,the experimental results have verified that the P2P stream mediatransmission system based on neighboring optimum selection is efficient and feasible.
