The Research of AFDX System Simulation Model

AFDX is a new generation network system of airborne devices. It is superior to use the simulation technology of network to research the real-time and deterministic performance in the AFDX system. For realizing the simulation of AFDX system, the simulation model of AFDX system should be built at first. Therefore, modeling has become the core issue about the simulation of AFDX system. After briefly introduced the AFDX system and its composition, on the basic of analyzing various function demands of different parts, the simulation models of AFDX End System, Switch and Virtual Link have been researched and built combined with the queuing theory. In accordance with the established models, a simulation of AFDX network system has been realized, and the deterministic problem of the AFDX network has been researched.
