摘要

针对广域虚拟数据空间系统中边缘客户端访问和共享远程数据时，数据冗余传输造成大量网络带宽浪费的问题，通过研究广域虚拟数据空间系统中的缓存技术，提出边缘缓存机制优化数据访问通路，将数据以文件粒度缓存在靠近边缘客户端的位置，从而提升上层应用访问和共享数据的性能。测试结果表明，作为虚拟数据空间系统的补充，提出的边缘缓存系统可提升广域数据共享的性能。

Abstract

Aiming at the problem of a large amount of network bandwidth wasted by data redundancy transmission when the edge client accesses and shares remote data in the GVDS

the caching technology in the wide-area virtual data space system was studied and an edge caching mechanism to optimize the data access path was proposed.The data is cached at a file granularity close to the edge client

thereby improving the performance of upper-level applications to access and share data.The experimental results show that the edge cache system proposed can improve the performance of wide-area data sharing as a supplement to the GVDS.
