| Abstract: | With the improvement of the overall performance of the aircraft and the rapid development of the avionics
system, higher and higher requirements are placed on bus network. Ethernet based on the RDMA (Remote Direct Memory
Access) transmission mechanism has been gradually promoted in the avionics system bus due to its high bandwidth,
low latency and ecological openness. The development of avionics bus network is introduced; comparison and analysis
are made between typical avionics buses, and 10G/40GE switching engineering prototypes are developed and tested,
providing a reference for the selection of next-generation avionics system bus networks. |
