Technical Research and Platform Implementation of the Protocol Conformance Test of AFDX Network Switch

The Avionics Full Duplex Switched Ethernet (AFDX) has been selected as backbone communication network in integrated module architecture (IMA) of avionics currently. According to the requirement to AFDX switch of ARINC 664 Part7, the protocol conformance test model of AFDX switch is built in this paper. The muster and feature of protocol conformance test of AFDX switch is analyzed, and the test method adopting concurrent, fault injection and integrity testing technique is presented. The test platform of protocol conformance test of AFDX switch is constructed and implemented, and the actual test effect is introduced.
