Local Area Networks (LANs) function to connect a number of Personal Computer (PC) and related products in a data transferring relationship which has its own protocol for establishing connections. The figure shows a Wide Area Network (WAN) or teleprocessing network 15 in which a host computer 13 is connected to a LAN 16 through a communication server 10. The architecture of the network 15 is described on pages 889-900 of this issue. The disclosed protocol does not depend upon a specific LAN, but rather can be implemented on any LAN which supports LAN-level sessions between computers. A session connection architecture which is independent of the underlying LAN protocol gives the WAN wider applicability. Programs written to the disclosed protocol may remain invariant when the LAN is swapped out from under them.
