为提高分布式存储系统中文件的获取速度,提出一种尾块动态调整的多节点协作并行下载算法,通过对文件分块下载中的最后一块进行调整使得多个并行下载流尽可能同时结束。对比实验结果表明本文的下载算法提高了下载速度,改善了用户的下载体验。
In order to improve the speed of obtaining files in distributed storage system, a multi-node collaborative parallel download algorithm of tail-block dynamic adjustment is proposed. Multiple concurrent download streams can be terminated at the same time by adjusting the last block of file block-download. The experimental results show that the download algorithm in this paper improves the download speed and improves the user’s download experience.
