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:
A generic and multi-role controller structure for data and communication exchanges is disclosed. In one aspect, the structure assumes the form of a single component and includes a capability forming a generic data and communication exchange controller, associated with at least: a capability forming a data storage/exchange buffer, a capability forming multiple connection interfaces to several data production/consumption units, one connection interface being associated with one data production/consumption unit, a capability forming multiple connection interfaces with several external data communication buses, and one connection interface being associated with one external data communication bus.
Abstract:
The invention relates to a message exchange controller structure (1) comprising means (3) forming a message exchange controller, associated with a member (4) forming a storage/exchange buffer, a member (5) forming interfaces for multiple connections to several message production/consumption units, and a member (6) forming interfaces for connecting to several external buses; which is characterized in that the means exchange controller-forming means (3) are able to recover redundant messages from external buses, store those messages in the storage/exchange buffer-forming member (4), recover those messages from the storage/exchange buffer-forming member (4), and process those messages so as to generate a resultant message (MF), to send it to at least one consumption unit.
Abstract:
A data transmission architecture, in particular for use in on-board avionics is disclosed. The data transmission architecture includes at least one main data transmission network with integrated functional nodes for connecting a plurality of peripheral data transmission networks to the main network, in order to provide data transmission between the networks. The data transmission architecture also includes a direct connection of peripheral networks to one another so as to allow the transmission of data directly between the peripheral networks without passing through the main network. The main network includes a plurality of associated sub-networks.

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.
