摘　　要：把周期性广播算法和批处理算法运用到分布式视频点播系统中,推导出实时混合型播放算法,新算法有效地解决了视频点播系统资源瓶颈问题;性能分析结果显示,新算法能够及时响应用户的请求,对客户端无存储要求,并且具有良好的效率、稳定性和扩展性。在当前带宽等资源相对匮乏及客户端无缓存的情况下,该文所述的播放算法是一个很好的选择。By application of Periodic Broadcasting protocol and Batch protocol to distributed VOD system,we propose a new video playing back protocol---Real Time Mixed Playing back protocol.The new protocol can efficiently solve the problem of resource bottleneck in VOD system.The results of performance analysis show that new protocol can respond user request in time,don＇t need storage at Client,and have good efficiencies,stability and expansibility.ln current condition of the scarcity of band-width resources and no storage for Client,the playing back protocol studied in this paper is a good choice.
