Data communications in duplicated network involves deciding in nodes whether to pass data packets, which it has received via horizontal connecting path, over horizontal or vertical path

摘要

The method involves connecting one or more nodes (4,4') per network together and to transmitter/receiver modules (1-3) via horizontal connection paths (11,21,31;11',21',31'), connecting each node of one of the two networks to a corresp. node of the other network via a vertical connection path (51), and deciding in the nodes whether to pass data packets, which were received via a horizontal connecting path, over a horizontal or vertical connecting path An Independent claim is also included for nodes for a data communications network.
