一种基于CollectCast的点对点的流媒体

Study on P2P media streaming based on CollectCast

在许多的P2P的数据共享的分布式系统中到底在网络上有多少节点能够或者愿意提供这些资源的支持,特别是在带宽方面.讨论了一种基于CollectCast的点对点的流媒体Promise系统正是对这种问题提出的一种解决方案,通过用多个发送节点来提供对一个接收节点的支持.通过仿真证实此流媒体系统能够在网络即使不稳定性的情况下在接收端都可以达到很优的播放质量.

For a media file of playback rate R0, a single sending peer may not be able or willing to contribute an outbound bandwidth of R0. Moreover, downloading the entire media file before playback is not the best solution, due to the potentially large media file size and thus long downloading time. A P2P media streaming Using ColleetCast was proposed as a P2P media streaming model that involves multiple sending peers in one streaming session. And evaluates the performance and discuss further optimization.
