摘要:
 机载通信网络技术是实现航空电子系统间大容量的高速数据交换的枢纽和核心，其性能和功能决定航空电子系统综合化程度的高低，是现代先进飞机航空电子综合化的关键技术之一。源于商用以太网技术、在国际民机中广泛使用的AFDX网络技术，具有低成本、高带宽、低延迟、确定性、高可靠性等诸多优点。文中在论述现有总线网络技术的基础上，介绍了AFDX技术。重点叙述了AFDX网络体系结构，给出了AFDX网络工作机制和流程，重点分析研究了AFDX网络协议及关键技术，为AFDX网络协议处理芯片的设计、实现、验证及系统应用提供了理论基础。
Abstract:
 Airborne communication network technology is the hinge and kernel to implement the high-speed,large-volume data exchan-ges among the avionics systems. The function and performance of the airborne data bus determines the avionics system integration level. Airborne data bus technology is one of the most significant technologies in the advanced avionics system integration of the modern air-plane. Rooted from the commercial Ethernet network technology,with the advantages of low-cost,high-bandwidth,low-lantency,high-reliability and so on,the AFDX networks technology has been widely used in the international civil airplanes. On the basis of the available bus network technology,AFDX technology is introduced. The architecture of AFDX network is discussed as a focal point,and working mechanism and working process of AFDX network is provided,and networking protocol and theoretical basis of AFDX is analyzed partic-ularly,which lays the foundation of theoretical basis for design,implementation,verification and system application of AFDX networking protocol processing chip.
