摘要
在Bittorrent协议和算法的基础上,提出了一种和Bittorrent协议兼容的分段顺序文件下载算法,很好地满足了用户边下载流媒体文件边播放的需求.以该算法为核心,给出了一种以Bittorrent文件下载系统为原型的流媒体服务系统实现.实验结果表明,采用分段顺序下载算法的客户端下载速率有所降低,不过该算法使得流媒体服务系统的负载能力比传统的流媒体服务系统提高了3～4倍,充分体现了P2P技术相对于集中式服务技术的优势.
Base on the Bitorrent protocol and algorithm a new algorithm was proposed which enable the user play the media file while it is being downloaded from the Bittorrent network.With the new algorithm,the implement of a new media service system was introduced.The experiment indicats that although the total download speed is lower than the Bittorrent system,the load capacity of media service system would be 3～4 times than the traditional media service system.
