| 摘 要： | P2P技术解决了传统流媒体应用中的不能支持大用户的问题.而数据调度算法一直是P2P研究中的热点问题.在给出了P2P视频直播系统中节点能力的定义和计算方法后,结合BT中的Rarest First策略,提出了一种基于节点能力的适用于P2P视频直播系统的数据调度算法.该算法既考虑了流媒体数据具有时间限制的特性,同时也考虑了如何能充分的利用节点的上传带宽,增进了系统的负载平衡.

| Abstract: | The traditional media streaming system can not support a large amount of users;the P2P technology can solve the problem.Data scheduling algorithm is a very important issue in P2P research.After giving the definition and calculating method of peer's capability,according to BT's Rarest First strategy,a data scheduling algorithm is given used in P2P live media streaming based on peer's capability.This Algorithm not only considered the time limited condition of media streaming,but also took account of how to fu... |
