CONSTITUTION:Networks 3a-3c connecting computer systems 2a-2c to communication channels 1a-1c are identified respectively as the separate networks and mutually connected through gate ways 4a-4c. Each computer system 2 is equipped with a use starting procedure part 5, command analysis part 6, interface part 7 and address analysis part 8. The use permission of the remote computer system is judged according to the identifier of th user, the identifier of the computer system executing the connection processing and the identifier of the network to which the computer system belongs, and a use procedure is executed.
