Architectures of the embedded avionics networks, such as that of the future Airbus A380, currently know important evolutions. This is principally due to the increase in the complexity of the embedded systems, in term of rise in number of integrated functions and their connectivity. The evolution in the technologies of the local area networks of data transmission makes it possible to convey new answers to the airframe manufacturers. In particular, Switched Ethernet technologies which are being implemented as an avionics architecture, even if the non-determinist character of certain networks must be compensated by strong assumptions.
This paper presents a simulation model for dimensioning an Avionics Full Duplex Switched Ethernet network (AFDX) and studying the performances of this network. Comparison with other deterministic studies which use Network Calculus is also performed in this paper.
