Network system supporting network communication among temporarily connected mobile computers and flexible file sharing among computers
First Claim
1. A network system of computers connected by a network, comprising:
- connector means for connecting a computer to the network;
fixed address storage means for storing a fixed address on the network corresponding to the connector means;
computer address acquisition and storage means for acquiring and storing a computer address of the computer connected at the connector means from the computer; and
means for converting an address contained in a message for a communication between the computer and the network according to one of the fixed address stored in the fixed address storage means and the computer address stored in the computer address acquisition and storage means.

Abstract
A network system, in which a plurality of computers are connected to a network at a plurality of connectors, and a plurality of address conversion devices are provided in correspondence to the connectors. In each address conversion device, a fixed address on the network corresponding to each address conversion device is stored, while a computer address of one computer connected at one connector corresponding to each address conversion device is acquired and stored. Then, a source address contained in a message transmitted from that one computer to the network given in terms of the computer address is converted into the stored fixed address, while a destination address contained in a message transmitted from the network to that one computer given in terms of the fixed address is converted into the stored computer address.
