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.

Key words: wide area network, edge cache, global virtual data space, shared data access performance
