提供高健壮性和鲁棒性的流媒体直播服务是一项具有挑战性的工作.提出了一种基于BT(Bittorrent)协议的P2P流媒体直播系统和一种与BT协议兼容的流媒体服务框架.该直播系统以BT协议为P2P网络管理协议,采用播放区间和预取区间两级缓存空间,播放的同时下载预取区间内容,客户节点获取数据时采用BT协议中的数据调度策略.模拟实验结果表明,BT协议可以较好地满足流媒体直播服务的要求.

Supplying P2P live streaming service with high robust is a challenging problem. A new service flame of P2P streaming which is compatible with BT Protocol and a new P2P live streaming service model which is based on BT protocol are proposed. This live strea-ming system adopts the BT protocol to manage P2P network, uses the playing extent and prefetching extent, downloads the prefetching extent when plays the playing extent data segment, and adopts BT's data scheduling algorithm. With the envalution, the BT protocol satisfy the need of P2P live streaming service efficiently.
