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.
