Integrated network reliability research for AFDX

Abstract

By discussing network inherent failure mechanism of AFDX (Avionics Full Duplex Switched Ethernet), this paper establishes an integrated reliability analysis architecture of AFDX. Choosing throughput as important indicator, the integrated AFDX reliability evaluation system is established by combining device failures together with PRNR. Finally, by opnet simulation, it shows that workstation quantity and the average packet size are important factors influence integrated network reliability.
