Simulation system and simulation method of AFDX (Avionics Full Duplex Switched Ethernet) network

Abstract

The invention provides a simulation system and a simulation method of an AFDX (Avionics Full Duplex Switched Ethernet) network. Both an end system and an exchanger in the AFDX network are abstracted into discrete event simulation nodes by adopting a discrete event mechanism, AFDX information is abstracted into discrete events for the discrete event simulation nodes, the transmission behavior of the AFDX information in the end system and the retransmission behavior of the AFDX information transmitted from the end system between different ports of the exchanger are simulated by utilizing the transmission and retransmission behaviors of the discrete events, and performance parameters of the AFDX network can be obtained on the basis of the simulation. According to the simulation system and the simulation method, a real information operation mechanism of the AFDX network is simulated by utilizing the discrete events, so that the performance parameters of the AFDX network after each discrete event is ended can be conveniently counted, the system design of the AFDX network is further optimized, and the iteration cycle of the system design is shortened; additionally, an end system simulation module in the simulation system is automatically introduced on the basis of an interface control document, so that the system verification time is reduced.
