摘要
随着航空需求的不断提高,传统的航空总线协议已经不能满足下一代航空电子系统对高速数据通信的要求,研究下一代航空数据网络是人们一直关注的问题。航空全双工交换式以太网(AFDX)在传统以太网的基础上采用商用现成技术(COTS)和开放式标准,是下一代航空数据网络的最佳选择。文章介绍了AFDX系统的特点、结构,并对AFDX的不确定性给出了可行的改进方案。
As the increment of need in avionics, the traditional avionics bus standard could not meet the requirement for data communication in next generation avionics electrical architecture. There is a strong interest in researching the next generation avionics data networking. Full Duplicate Switch Ethernet（AFDX）which adopts Commercial Off-The - Shelf（COTS） technology and open standards based on Ethernet will be the ideal selection for next generation avionics digital networking. This paper introduces the characters and architecture of the AFDX, and gives some feasible suggestions on the non-determinism.
