Abstract: A device for distributing information and its fault management process which improves the robustness of a network, such as in an aircraft, a boat, or a train. The device or process includes one or more splitters of which an upstream input output is linked to a first end of a chain including stations, at lower overdimensioning cost, and with dynamic management of a fault which renders it transparent or of very short duration. A second end of the chain is linked to a downstream input output of another splitter and a fault management procedure is implemented activating or otherwise one of the ends of a chain depending on the nature and the conditions of the fault. Preferably, addresses of the elements of the network can reflect its topology and facilitate the shunting of the addresses of the stations between splitters.

Abstract: The present invention relates to the management, on board an aircraft, of the aeronautical digital telecommunications networks ACARS and ATN. It covers a method for automatic choice of the transmission sub-network of the ACARS or ATN networks which is most appropriate for the exchange of digital messages with the ground, taking account of the capabilities of the equipment of the aircraft, of that existing on the ground in the area overflown, of the costs and of the reliabilities of the possible links, and of the preferences of the pilot, of his airline and of the control services.
