This article describes a method of extending intra-local area network (LAN) device sharing functions of LAN servers to an inter-LAN sharing capability utilizing a concatenation entity. Conventionally, intra-LAN device sharing permits I/O requests to be redirected away from local devices to a LAN server. This inter- computer communication is via a higher-level protocol which uses logical sessions provided by the LAN's transmission services. However, when multiple LANs are connected by gateways with different transmission services, the servers on one LAN are no longer addressable by computers on a different LAN. In the method disclosed herein, a server in one LAN is made addressable to computers on a different LAN.
