Abstract

A network for data transmission between nodes interconnected by transmission paths on which a predefined data signal is continuously transmitted to sequentially reach each node. Data traffic is controlled by apparatus responsive to receiving the predefined data signal a predetermined number of times and generating node signals each varying in time in accordance with data traffic on the network to control node access thereto. Multiple nodes are enabled to mutually write data onto the network proportional to the communication network data traffic independent of the network location of the predefined data signal.
