Abstract :
This paper develops a comprehensive simulation model for Avionics Full-duplex switched Ethernet (AFDX) network based on OPNET platform. Accordingly, the performance of AFDX networks is analyzed. The effect of frame size, switching delay and changing frames transmission order on the AFDX network performance are investigated. It is found that using faster switches and small frame size reduces the fixed part of the end to end delay. Also, it affects the variable part of end to end delay due to changing of delay in switches´ buffers and frames transmission order.
