摘　　要：航空电子全双工通信以太网交换(AFDX)是一个基于标准定义的电子和协议规范,用于在航空子系统之间交换数据,能够从一个交换机桥接到其他的交换机内部网络。这个稳定性的网络允许连接冗余(双物理连接)来保证带宽和服务质量。AFDX还允许连接其他标准总线(ARINC429或者MIL-STD-1553),并且允许通过网关和路由与其他的适应ARINC-664但非确定的网络进行通信。基于此,笔者重点探讨了上位机测试软件的开发过程及验证测试,希望能够为相关研究提供借鉴。Avionics Full-Duplex Communication Ethernet Exchange(AFDX)is an electronic and protocol specification based on standard definitions used to exchange data between aviation subsystems,which can bridge from one switch to the internal network of other switches.This stable network allows connection redundancy(dual physical connection)to ensure bandwidth and quality of service.AFDX also allows to connect to other standard buses(ARINC429 or MIL-STD-1553),and allows communication with other ARINC-664 but not deterministic networks through gateways and routing.Based on this,the author focused on the development process and verification test of the host computer test software,hoping to provide a reference for related research.
