Abstract:

One of the key problems of global distributed storage systems（GDSS） encountered is how to implement the file access interfaces which can efficiently  access the distributed files. After analyzing several normal distributed file systems, based on the characteristics of global distributed storage systems, this paper designs the file access mode at the client end, and implement a series of file access interfaces, with which users con conveniently access the distributed files as if they are local.

Key words: global distributed storage system, file access mode, file access interface
