<p>A local area network, having a layered architecture, comprises N transmitting and receiving stations, N >/= 2, said stations (11) being interconnected in series by a transmission medium (14) to form a ring in such a way that the inactive (dead) stations are disconnected from the ring and the active (live) stations are inserted in the ring. Said transmission medium comprises a data transmission channel (Vd) and a signalization channel (Vs) which are unidirectional and of opposite directions. Processes and means of access to said transmission means, which are identical in each of said stations, enable said active stations to accede simultaneously and without conflict, in a controlled manner, to said transmission medium in accordance with a protocol for multiple access by distributed traffic control.</p> |
