Method of relaying file object, distributed file system, computer readable medium recording a program of file object relay method and gateway computer, allowing reference of one same file object among networks

Abstract

A method and system for relaying a file object used in a gateway computer allowing the change of various parameters settings, dependent on particular networks, in a simple manner. The method and system further allowing reference of a file object referred to when a client computer was first connected to a certain network even when the client computer is then connected to another network in a simple manner. The method and system provides for relaying a file object in accordance with any of a plurality of control structures corresponding to a plurality of networks, respectively. The gateway computer includes storage for storing a file object. Each of the plurality control structures has an address of a representative gateway computer to which a client computer is connected. The method of relaying the file object includes the steps of receiving an event, when the event is a request for switching between the control structures, switching various parameters in accordance with that one of the control structures to which switching is requested, when the event is a request for getting the file object transmitted by the client computer, reading and relaying to the client computer the file object from either one of an upstream computer and the storage, and storing the relayed file object in the storage.
