Avionics Full Duplex Switched Ethernet (AFDX) has been widely used in civil aircraft avionics systems because of its advantages of low cost, delay, high reliability, real-time performance and strong scalability. The performance of AFDX network has a direct influence on the real-time data transmission, the integrity and effectiveness of information transmission of airborne avionics system. It is difficult for traditional tests to simulate on-site working conditions. Therefore, OPNET network simulation tools are used to conduct high-precision simulation and modeling of AFDX terminals and AFDX switches, and a semi-physical AFDX network system composed of simulation parts and physical parts is built as the target object of network analysis and optimization. Finally, the performance of the constructed network system is tested by means of network acquisition and monitoring, which provides an effective verification method for the performance analysis and network optimization of avionics network system. The design can improve the reliability and quality of airborne network, and play a guiding role in practical application and product design.
