摘要
Linux下常见的十余种文件系统的实时性都不理想。针对归档存储数据的特点,提出一种实时文件系统设计方案,并且设计了一种按照时间点检索的检索算法。文件系统的设计以减少读写文件时的不确定延迟为目的,主要减少写时寻道时间,简化索引机制,简化空闲磁盘块管理。
Linux has supported more than ten sorts of file systems, but all the file systems＇real -time performance is not very good. According to the characteristics of the archive data, this paper intended to show a design of real - time file system, and propose a retrieval algorithm to search data by time. In order to reduce the uncertain delay of reading and writing files, the main works focus on reducing seek time, simplify- ing index mechanism, and simplifying free disk blocks management.
