分析了基于磁盘系统的视频服务器的准入策略,提出了基于磁盘系统的为保证视频服务器接纳更大数目用户的准入算法,即在每个服务周期中每个用户要求检索到的数据块的数目与其对应的回放速率成比例,视频服务器通过过量预约资源来允许更大数量的客户数。这种算法允许视频服务器接纳更大数目的用户,满足多用户媒体回放的稳态性和迁移态连续性的要求。
This paper analyzed the access strategy of the video server which was based on the disk system. In order to guarantee the larger number of users accepted by the video storage server, it put forward a disk-system-based access algorithm, which meant that the data block numbers searched by each user in each cycle of service were in proportion to the playback rate correspondingly. This algorithm can meet the demands of the steady supporting the multi-user media playback and continuity of migration.
