摘要:
In a distributed file system, a file server stores files, and a cache server stores copies of files, server information, and control information. The server information defines a communication procedure used in communication with the file server, and the control information controls a client so that in case of necessity of a file, the client sends a file-acquisition request to the cache server when the cache server is in operation, and to the file server in accordance with the server information when the cache server is not in operation. The cache server sends to the client the control information and the server information in response to a startup notice sent from the client, and sends, in response to a file-acquisition request sent from the client, one of the copies of the files corresponding to the file-acquisition request received, to the client.
