Abstract: A simulation or test system for a network architecture of computers and active equipment items, in particular on board an aircraft, and a corresponding method are disclosed. The system comprises a simulation unit comprising models simulating at least one part of the computers. Moreover, each computer or simulation model is able to communicate on a real network through a corresponding active equipment item to which the computer, simulated if need be, is directly connected in the network, and the simulation unit may acquire a message sent out by a computer or a simulation model on the network, and transmit the acquired message to simulation models that are recipients thereof. The simulation unit acquires the message at the corresponding active equipment item to which the sending computer or simulation model is directly connected.

Abstract: This invention relates to a simulation or test system (1?) for a network architecture of computers (10-15) and active equipment items (20-25), in particular on board an aircraft, and a corresponding method. The system comprises a simulation unit (100) comprising models (Mi) simulating at least one part of the said computers (10-15). Moreover, each computer or simulation model is able to communicate on a real network (2) through a corresponding active equipment item (20-25) to which the said computer, simulated if need be, is directly connected in the network, and the simulation unit (100) may acquire a message (MESS) sent out by a computer or a simulation model on the network, and transmit the acquired message to simulation models (Mi) that are recipients thereof. According to the invention, the simulation unit (100) acquires the said message at the corresponding active equipment item (20-25) to which the sending computer or simulation model is directly connected.

Abstract: The invention relates to a system for simulating at least one item of equipment missing on an AFDX network and for testing such a network comprising at least one real item of equipment, which uses non-specific computer means including: a simulation layer (21) controlling at least one Ethernet controller (22), at least one commercially available Ethernet switch (42) to switch data.
