| 摘 要： | 应用排队理论证明了P2P流媒体系统在稳态时可模型化为多个M/M/n排队系统串联的排队链,在此基础上以节点的播放缓存状态为研究对象,建立了P2P流媒体系统的稳态传输模型。考察了不同chunk调度策略下节点的传输特性,以此验证模型的准确性,并进一步考察了P2P流媒体节点数量、节点缓存大小对传输特性的影响。

| Abstract: | It was proved that the P2P streaming system could be modeled by a queuing chain which was composed by multiple M/M/n queuing system according to the queuing theory.Based on this result,the stationary transmission model of P2P streaming was proposed by the analysis on the peer buffer state variation.The transmission characteristics under different chunk schedule strategies were examined by the model,and the results validated the rationality of the proposed model.Further more,the impact of peer number and buffer size on the transmission characteristic was examined. |

| Keywords: | peer-to-peer streaming stationary transmission model session quantity traffic chunk schedule strategy |
