Abstract: The P2P real-time video broadcast technology has been quite hot.The BT protocol which is a particular mature P2P protocol has a good performance in downloading data.Based on the BT bucket priority downloading algorithm,an improvement of the piece-selection algorithm is proposed.This algorithm meets both the real-time requirement and the smooth requirement,which successfully improves BT protocol to be fit for video broadcasting.And this provides a new business usage of BT protocol.
Key words: P2P protocol, video broadcast, BT protocol, downloading algorithm
摘要: P2P协议应用于视频播放是一项热门技术,BT协议作为P2P协议族中的成熟协议,其在文件共享下载方面有着优异的表现。从BT协议的优先级桶式下载算法出发,提出基于速度评价的片选择下载算法,该算法适应视频播放实时性和平滑性要求,使得BT协议成功应用于视频播放,从而为BT协议的应用提供了一种新的商业模式。
