摘　　要：AFDX网络满足新一代航空电子系统主干网络通信的高实时性、高可靠性以及高带宽要求,其核心协议为ARINC664 Part7。该协议具有完整的体系结构,运用虚链路技术,满足了AFDX网络高实时性要求,采用余度容错机制,实现了AFDX网络的高可靠性。在AFDX网络综述的基础上,详细分析了端系统协议与交换机协议,其中端系统协议涉及到通信端口、余度容错、虚链路等关键技术,交换机协议包括了警管、过滤、交换调度等关键技术,为AFDX网络关键协议芯片及后续产品的研制奠定理论基础。AFDX network meets the requirement of new generation avionics system, which has high real time capability, high- reliability and high- band width. The core protocol of AFDX network is ARINC664 Part7. The protocol has the fully system structure,the use of virtual link technology meets the requirements of high real time capability for the AFDX network, the redundant fault-tolerant mechanism is used to realize the high- reliability of AFDX network. This thesis analyzes end system and switch protocol in detail on the base of summarizing the AFDX network. The switch protocol includes key technology such as the police tube, filter and exchange of scheduling. It is the theoretics base for the design of AFDX network key protocol So C and products.
