| 摘 要： | P2P直播作为流媒体传输中IP组播的替代方案,其物理承载以IP单播为基础。而近年来P2P直播在实际使用中反映出IP单播在传输性能上的瓶颈。随着技术、产业和政策的发展,单播、组播和广播三种物理传输网逐渐融合,P2P覆盖网不但能够将多网的接入融合提升为应用融合,更应该利用多网融合的优势提高P2P直播的性能。从P2P直播网的应用情况、覆盖网与物理网的融合以及P2P直播分发模式三个方面,分析了直播覆盖网利用多网融合优势的关键问题,最后总结了目前P2P直播中存在的可改进因素,并指出了利用多网融合进行P2P直播技术优化的研究重点。

| Abstract: | P2P Live streaming is the alternative of IP multicast in streaming media transmission,the physical bearing way of it uses IP unicast as the basis.However,recently IP unicast causes some transmission performance bottlenecks in the practices of P2P Live streaming.Along with the development of technology,industry and policy,three physical transmission networks including the unicast,multicast and broadcast are in the accelerated process of integration.The P2P overlay networks can upgrade the access integration ... |
