Data processing stations communicating system, has groups of processing stations, where stations of same group communicate via internal network and of different groups communicate via external network

摘要

The system has groups (Fi, Fj) of data processing stations, where stations of same group communicate via an internal network (ICPL) and stations of different group communicate via an external network (Eth). Gateways (Pi, Pj) connecting respective groups to the network (Eth) have an Internet protocol router that exchange data blocks between a transmitting station (k) and a destination station (l).
