摘要 描述了视频点播系统的用户允许控制和节目允许控制等多级允许控制方案。重点 叙述了基于节目流行度的节目允许控制方法。对基于节目流行度的允许控制算法进行了数值 分析,表明了不同的基于节目流行度的允许控制策略对整个系统新请求阻塞概率的影响。 This paper describes multiple level admission control scheme. Espec ially, the popularity-based admission control arithmetic is studied in detail. T hrough numerical analysis, the effect of different popularity-based control poli cies on overall system blocking probability is shown.
