摘要
航空电子全双工交换式以太网(Avionic Full Duplex Switched Ethernet,AFDX)是空客公司为了满足航空电子发展的需求(如空客A380)而建立起来的一种高性能航空数据总线。分析了AFDX交换机处理数据帧的一些特点,构建了一套AFDX交换机端口缓冲能力测试系统,并对其系统组成和测试原理进行了详细的介绍。最后,介绍了该系统的实现,验证了该系统具有很好的性能。
Avionic Full Duplex Switched Ethernet（AFDX） is a switched interconnection designed to meet requirements related to the ever increasing demand for civil aircraft such as A380.In this paper,features of processing frames for AFDX switch are analyzed,a system for testing port buffer capacity of AFDX switch is created,and the principle of testing is introduced in detail.The implementation of this system is introduced in the end,which proves that this system has good performance.
