Abstract

This network comprising 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 so as to allow information to propagate in both directions of flow of the network, and each node includes at least one first and one second associated port, for information input/output, connected to adjacent nodes by corresponding information transmission means and the operation of which is controlled exclusively and sequentially, by communication automaton means, between an operating mode for the asynchronous reception of information from its adjacent nodes and an operating mode for the synchronous transmission of information to the nodes adjacent thereto, and in that the communication automaton means are suitable for switching the associated ports of the node from their reception mode of operation to their transmission mode of operation, after, for each of them:

either the reception of valid information and the reception of a timing signal internal (60) to the node;or the expiration of a predetermined length of time (61) for the non-reception of valid information.
