摘　　要：传统优化技术在随机读、混合读和数据一致性方面性能差,为解决这一问题,提出USB存储设备MTU值配置优化技术研究。先采集USB存储设备行为数据,再利用纠删码技术,设置MTU值配置存储总容量。考虑到数据数量过大,设计层次式文件管理架构记录文件属性。在此基础上,为优化存储数据,采用扁平式存储结构,实现USB存储设备MTU值配置优化。由此,完成USB存储设备MTU值配置优化技术的研究。实验在release 5.5操作系统下完成,分别测试两种优化技术随机读、混合读和数据一致性的性能。实验结果表明,使用所提技术能够达到近似最优的性能,数据访问开销比例更少。Traditional optimization technology has poor performance in random reading,mixed reading and data consistency.To solve this problem,a research on MTU value configuration optimization technology is proposed for USB storage devices.Firstly,the behavior data of USB storage device is collected,and the MTU value is set to configure the total storage capacity by using the erasure code technology.Considering the large amount of data,a hierarchical file management architecture is designed to record file attributes.On this basis,in order to optimize the storage data,flat storage structure is adopted to optimize the MTU configuration of USB storage devices.Thus,the research of MTU value configuration optimization technology for USB storage devices is completed.The experiment was completed under release 5.5 operating system,and the performance of random reading,mixed reading and data consistency of the two optimization techniques were tested respectively.The experimental results show that the proposed technology can achieve approximately optimal performance with less data access overhead.
