Abstract

See full text

A broadcast data transmission station for use in a data transmission system. The station includes a traffic amount counter for computing the amount of broadcast data present on a transmission line during a unit time period. A comparator indicates whether the traffic amount computed by the traffic amount counter has reached a predetermined limit. If the limit has not been reached, a transmission execution circuit allows the broadcast data to be sent on the transmission line. If the limit has been reached, a retransmission attempt circuit and delay timer cause the station to wait a delay time and then compare the traffic amount with the limit again. A retransmission attempt counter computes the number of attempts to send the same broadcast data, and a suspension circuit suspends further attempts to send the same broadcast data when the number of attempts counted by the retransmission attempt counter reaches another predetermined limit.
