Abstract The network according to the invention, including functional nodes connected in series by information transmission means, in which the information assumes the form of discrete messages propagating from node to node in the network, is characterized in that the information transmission means between the nodes are bidirectional to allow information to propagate in both circulation directions of the network, and each node includes at least one first and second associated information input/output port, connected by corresponding information transmission means to neighboring nodes and the operation of which is controlled exclusively and sequentially, by means forming a communication automaton, between a mode of operation with asynchronous reception of information from its neighboring nodes and a mode of operation for synchronous transmission of information to its neighboring nodes. ## Claims ### Claim 1 An information transmission network, comprising: functional nodes connected in series by information transmission devices, in which the information assumes the form of discrete messages propagating from node to node in the network, wherein: the information transmission devices between the nodes are bidirectional to allow information to propagate in both circulation directions of the network, each node comprises at least one of a first and a second associated information input/output port, connected by corresponding information transmission device to neighboring nodes and the operation of which is controlled exclusively and sequentially, by a communication automaton, between a mode of operation with asynchronous reception of information from its neighboring nodes and a mode of operation for synchronous transmission of information to its neighboring nodes. ### Claim 2 (depends on 1) The information transmission network according to claim 1, wherein the communication automaton is suitable for switching the associated ports of the node from their reception operating mode to their transmission operating mode, after, for each of them: either receiving valid information, or the expiration of a predetermined period of time for non-reception of valid information. ### Claim 3 (depends on 2) The information transmission network according to claim 2, wherein the communication automaton is suitable for switching each of the associated ports in return, from its transmission operating mode to its reception operating mode, after the end of transmission of the information by the port. ### Claim 4 (depends on 1) The information transmission network according to claim 1, wherein the ports associated with each node are connected to a buffer-forming device using first in-first out logic. ### Claim 5 (depends on 1) The information transmission network according to claim 1, wherein the nodes include more than two associated input/output ports. ### Claim 6 (depends on 1) The information transmission network according to claim 1, wherein the nodes are connected in a closed loop using the information transmission devices. ### Claim 7 (depends on 1) The information transmission network according to claim 1, wherein the nodes are connected by the information transmission devices, in at least one branch whereof the end nodes are suitable for operating in a mirror mode for returning information to the transmitting neighboring node. ### Claim 8 (depends on 1) The information transmission network according to claim 1, wherein the nodes are connected by the information transmission devices, in a connecting branch of other nodes connected in the closed loop by the information transmission devices. ### Claim 9 (depends on 1) The information transmission network according to claim 1, wherein each node is suitable for switching into the mirror operating mode for returning information to a neighboring transmitting node in the event a malfunction is detected. ### Claim 10 (depends on 1) The information transmission network according to claim 1, wherein at least some of the nodes comprise a generating service information unit generating service information intended to be transmitted over the network. ### Claim 11 (depends on 1) The information transmission network according to claim 1, wherein at least some of the nodes comprise a generating error information unit generating error information intended to be transmitted in case of non-reception of valid information from a neighboring node within a predetermined period of time. ### Claim 12 (depends on 1) The information transmission network according to claim 1, wherein the information transmission devices include a wired connection. ### Claim 13 (depends on 12) The information transmission network according to claim 12, wherein the information transmission devices comprise pairs of twisted wires. ### Claim 14 (depends on 12) The information transmission network according to claim 12, wherein the information transmission devices include coaxial cables. ### Claim 15 (depends on 1) The information transmission network according to claim 1, wherein the information transmission devices include optical fibers. ### Claim 16 (depends on 1) The information transmission network according to claim 1, wherein the information transmission devices include wireless connections. ### Claim 17 (depends on 1) An information transmission network node intended for a network according to claim 1.
