Current space launchers, and particularly Ariane 5, use the deterministic network MIL-STD-1553B. According to the new objectives of cost and system mass reduction and of multimedia traffic support, this technology is not optimal anymore. Among the potential candidates, this thesis highlights the fact that such objectives can be achieved through the use of Ethernet standard based on components-on-the-shelf. The first contribution focuses on time performance evaluation of switched architectures. The gain and limits related to the communication mode (from master/slaves to producers/consummers) and future avionic distribution are studied. This study relies on a deterministic evaluation of the end-to-end delay by using network calculus, simulati...
