Abstract
The data transmission control system includes a transmitter/receiver data buffer for temporarily storing data transmitted to or from a ring transmission line, a basic clock generating device for generating a basic clock and its phase data to be transmitted in a packet to the next node to synchronize a basic clock of the next node, and a controller for controlling data storage of the data buffer and timing of data transmission to the ring transmission line so as to produce a constant transmission time, thus making it possible to use a circuit switching method in the token ring network.
