Abstract:
A functional node for an information transmission network and corresponding network are disclosed. In one aspect, the functional node includes at least one module for distributing messages between input and output ports. The distribution module includes at least one combination of at least three ports, including a first input port connected to a second output port by a first capability for unconditionally propagating messages, not depending on the messages. The first and/or second ports are connected to a third port by a second capability for conditionally propagating messages, depending on the messages.
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.
Abstract:
An information transmission network and corresponding functional node are disclosed. In one aspect, the information transmission network includes functional nodes connected to one another by an information transmission capability. The information is in the form of discrete messages propagating from node to node in the network. At least some of the nodes have at least two operating modes, one operating mode defined only by the configuration of the physical layer of the node referred to as 1 of the OSI model and one operating mode defined at least by that layer and the link layer of the node referred to as 2 of the OSI model.
