Study of Fibre Channel Interconnections in Future Avionics System

The advanced integrated avionics is recommended,and the requirement of united fibre interconnection is studied.The reliability,fault tolerance ability and determinacy of Fibre Channel(FC) protocol are enumerated.FC as an avionics interconnect for future is evaluated.One avionics architecture for future base FC is proposed.The FC Standards body allow mapping to Upper Level Protocols(ULP) through an intermediate mapping level.Some of the topologies and protocols(VIA,ASM,1553,RDMA,AV)are suited for Avionics applications,where the movement of data between devices must take place in a deterministic fashion and needs to be delivered very reliably,FC-AE-1553,FC-VI and FC-AV which are used as an avionics interconnect for future is proposed and analyzed.The analysis of ULP has a directive effect in the phase of avionics system design.
