ABSTRACT:
A data transmission system is described, comprising a number of stations connected together in a ring. One of the stations acts as primary and can send a message at any time. The other stations act as secondaries and can transmit messages only when they receive a polling signal (EOP) from the primary. The primary keeps a record of the number of messages sent by each of the secondaries and, after it has itself received a predetermined number of messages, the primary attempts to pass on the role of primary to the secondary that has transmitted the greatest number of messages.
