摘要
介绍先进综合化航空电子系统结构及先进综合化航空电子系统对采用光纤统一网络互连的要求;列举光纤通道(FC)互联网络的高可靠性、容错性和确定性等指标,并评估其适于作为新一代航空电子系统互连标准;描述FC在未来航空电子系统应用中复杂的体系结构和多种上层映射协议共用的解决方案;介绍1553上层映射(FC-AE-1553)、虚拟接口结构上层映射(VIA ULP)、音频视频上层映射(FC-AV)等三种FC的上层映射协议适用于未来航空电子系统应用的特点,分析三种上层映射协议在未来航空电子系统中的应用。
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.
