高清媒体播放器和交互式网络电视(IPTV)机顶盒中的存储管理系统通常不足以支持高清媒体文件的高码率并行播放和下载.提出并实现一种新的文件系统Boaz,它使用较大的簇并应用基于预期文件大小的启发式数据块分配算法使得文件的存储空间更连续,元数据的更新频率降低.Hash表和B+树相结合的策略帮助简单快速地进行文件名解析,第2版日志块设备层(JBD2)作为日志机制保证文件系统数据的一致性.对Boaz的一个简单实现的测试结果表明,新的文件系统在IPTV机顶盒磁盘上的读写速度比Ext3/4快7%.
Storage management systems in HD media players and IPTV set-top boxes are often not enough to support high bitrate parallel playback and download of HD media files.A new Boaz file system is proposed and implemented that uses a larger Clustering and applying heuristic chunk allocation algorithms based on the expected file size make file storage more contiguous and metadata update less frequently.The strategy of combining hash tables and B + trees helps to quickly and easily perform file name resolution, version 2 The Log Block Device Layer (JBD2) serves as a logging mechanism to ensure file system data consistency. A simple implementation of Boaz’s test results show that the new file system reads and writes 7% faster than Ext3 / 4 on IPTV set-top disk drives.
