Abstract: Aiming at the traditional avionics bus can not meet the requirement for rapid and real-time data communication in next generation avionics electronic system, Avionics Full Duplex Switched Ethernet(AFDX) is put forward. This paper introduces the characteristics, architecture, communication mechanism and protocol stack of AFDX network, gives the primary design idea of AFDX end system and network switch, and presents their hardware structure and software flow. It has definite reference and extending value to AFDX communication network.
