摘要
为了满足市场对机载数据总线的实时性、可靠性和扩展性的要求,在IEEE 802.3以太网技术的基础上增加特殊机制来保证网络通信的高实时性、高可靠性和延迟确定性的航空电子全双工交换以太网(AFDX)协议应运而生。首先介绍机载数据总线的发展,指出其中的不足,进而引出并且分析AFDX协议,在此基础上就AFDX协议关键技术的实现做出了具体阐述。
In order to meet the market requirements of real-time, reliability and scalability for airborne data bus, AFDX protocols emerge as the times requirement, which adds special mechanisms based on IEEE 802.3 Ethernet technology to guarantee high real time, high reliability and delay certainty of the network communica- tion. Firstly, the development of airbome data bus is introduced, its deficiencies are pointed out, and then the AFDX protocol is introduced and analyzed. Based on these, the realization of the key technologies is elabora- ted.
