| 摘 要： | 随着多媒体技术和网络技术的快速发展,融合数字录像、DVD播放、视频点播和网络共享等功能的DVD录像机(DVD Recorder:DVR)正成为新的研究热点,DVR网络信息共享也越来越受到人们的重视.通过分析DVR文件存储和文件访问的特点,在现有的TCP/IP协议和FAT32文件系统的基础上,针对DVR设计了一种高性能的DVR网络文件系统DNFS(DVR Network File System).在百兆以太网环境下对DNFS性能进行了测试,测试结果表明,DNFS随机读的性能同SMB(Server Message Block Protocol)相接近,而DNFS顺序读的性能要比SMB高10-20%左右.
