【摘要】 研究了大量视频在磁盘组上的安置和接纳计算方法。基于视频的特性、视频的流行性及磁盘的特性,提出了一个优VBRMZVBRMZ化的存储模式及相应的接纳算法,和其它现存算法相比,结果显示它能支持更多的流数、在作品流行性变化的情况下有更好的适应能力。更多还原

【Abstract】 This paper focuses on large-scale video objects’ placement and admission on the multi-zone disks. Firstly, the paper proposes a MDSP algorithm places multi-video on multi-disk and some admission control algorithms, basing on rate variability, popularity of video, and the characteristic of MZ disk then compares the performance of MDSP with existing algorithm. The simulation result shows that MDSP can support more video streams and has well adaptability to variability of video popularity.更多还原
