摘要 文章将带宽平滑技术引入磁盘 I/ O调度 ,基于现已取得的研究成果 ,考虑磁盘 I/ O存取特性 ,提出一个针对VBR视频检索的整数块平滑调度算法 .算法所得的结果被证明是优化的 ,实验结果显示该算法在磁盘空间和磁盘 I/ This paper introduces the bandwidth smoothing techniques to disk I/O operating, Based on the work has been done well and the retrieval characteristic of disk I/O, proposes a blocks smoothing schedule algorithm. The algorithms result is smooth optimal by demonstrating in theory, experiment result shows the algorithm can improve the performance of the availability of disk I/O bandwidth and disk space.
