一种AFDX交换机的高效检测方法

The method of AFDX switch high efficient testing

航空电子全双工交换以太网(AFDX)是为航电信息系统之间进行数据通信而专门制定的协议标准,具有确定性、双余度和可靠性等优点,已成功应用于新一代航电网络。分析了ARINC 664 Part7中交换机章节及对应的通信架构等关键技术特点,提出一种高效率适合AFDX交换机的通信测试方法。通过测试与验证,证明该方法对通信功能的测试正确且效率较高。

Avionics Full Duplex Switched Ethernet（AFDX） ,an avionics specified Ethernet communication protocol standard, is the new generation aircraft data network, with the feature of strong real-time, redundant and high reliability and so on. By analyzing the characteristics of communication structure in the ARINC 664 Part7, a highly efficient communication test method suitable for AFDX switches is proposed. Through testing and verification, it is proved that the method is correct and efficient in communication function testing.
