METHOD OF CONTROLLING DATA TRANSMISSION AND RECEPTION IN A LOCAL COMMUNICATION NETWORK, AND DATA TRANSMISSION SYSTEM FOR THE APPLICATION OF THE METHOD

摘要

The method for use in a local network comprising a pilot station and local stations. Each station of the network is successively allocated the right to transmit a message on the transmission medium on which the messages are transported. This right to transmit is allocated to a station when its own address is indicated by its address indicator. The transmission of a message by the station having the right to transmit increments the address indicator of all stations, thus allocating the right to transmit to a next station. If a station remains silent when it has the right to transmit, the pilot station substitutes for the silent station. The method also concerns the detection of errors and the recuperation of incorrect messages. Each station of the system has a table which makes the state of the other local stations known at any instant.
