    • 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.
    • 在分布式文件系统中,文件服务器存储文件,缓存服务器存储文件副本,服务器信息和控制信息。 服务器信息定义与文件服务器通信所使用的通信过程,控制信息控制客户端,以便在需要文件的情况下,当高速缓存服务器处于等待状态时,客户端向缓存服务器发送文件获取请求 操作,并且当缓存服务器不在运行时,根据服务器信息到文件服务器。 缓存服务器响应于从客户端发送的启动通知向客户端发送控制信息和服务器信息,并且响应于从客户端发送的文件获取请求,发送对应于的文件的副本之一 收到的文件获取请求给客户端。

    • A distributed search system that includes a plurality of agents connected on a network that includes an information resource provider. Each of the agents stores information corresponding to information resources in a storage device of a nearest agent as advertisement information. The stored advertisement information includes cost information. An agent which receives the advertisement information transfers the advertisement information to other agents in a range determined on the basis of the cost information. The cost information may be included in a search request of an information resource searcher making a search request to search the stored advertisement information. The information resource searcher sends the search request including the cost information to agents in a range of transmission corresponding to the cost information included in the search request.
    • 一种分布式搜索系统,包括连接在包括信息资源提供者的网络上的多个代理。 每个代理将与信息资源相对应的信息存储在最近代理的存储设备中作为广告信息。 存储的广告信息包括成本信息。 接收广告信息的代理在基于成本信息确定的范围内将广告信息传送给其他代理。 成本信息可以被包括在进行搜索请求的信息资源搜索器的搜索请求中,以搜索所存储的广告信息。 信息资源搜索器将包括成本信息的搜索请求发送到与包括在搜索请求中的成本信息相对应的传输范围内的代理。
