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。 更多还原-Application of queuing theory to prove the P2P streaming system can be modeled in the steady state multiple M/M/n queuing system tandem queuing chain, on the basis of the state of the node cache to play as the research object, the establishment of a P2P streaming steady-state transmission model of the system. Examines the transmission characteristics under different chunk scheduling policy node, used to verify the accuracy of the model and further investigate the number of affected nodes cache size on the transmission characteristics of P2P streaming nodes.
