AFDX network performance testing

Abstract

Avionics Full Duplex Switched Ethernet (AFDX) is a new aviation data bus, which has been successfully applied to the new generation of large aircrafts. AFDX is the core bus of data transmission in advanced airplanes, so it is of great significance to carry out the extensive research of AFDX. Whether the data communication is deterministic and reliable concerns the airworthiness of AFDX, so the methods of AFDX network performance testing are discussed. An AFDX experimental system is built up. In the experimental system, AFDX network performance testing about network latency is carried out. Through sending/receiving large quantities of data and errors injection, the test verifies the certainty and reliability of AFDX network as a result. The test also provides a large number of testing data for further research on network maintenance methods, fault diagnosis, and the airworthiness of AFDX. © 2014 Springer-Verlag.
