Abstract
A processor intercommunication system includes a plurality of stations which are interconnected by a transmission link, each station having an associated processor. Further, each station comprises means which provide a data link protocol mechanism for establishing and maintaining a multiplicity of logical connections or transfer sessions between the station and several other stations. Thus application programs of all kinds in the processors can communicate with programs or data files in remote processors and need not be involved in communication operations which are handled by the stations. Link access circuitry is provided also in each station for absorbing the physical and topological characteristics of the transmission link so that the data protocol circuitry establishing and maintaining logical connections is independent of these characteristics.
