- Whitepaper AFDX/ARINC 664: An introduction to the new avionic data network AFDX, its concept, design and realization
ARINC-664 (AFDX)
"Avionic Full-Duplex Switched Ethernet" (AFDX/ARINC664) is a deterministic aircraft data network bus system for public avionic transportation, railway and military systems. The network is based on standard IEEE802.3 Ethernet technology.
General Information
The benefit of using commercial off-the shelf (COTS) Ethernet components is to lower overall costs for the aircraft network. Hardware components, cables and test equipment for Ethernet are field proven and much more affordable than the previously used avionic specific solutions. Ethernet itself won´t meet avionic network requirements. Therefore, AFDX extends the Ethernet standard by adding Quality of Service (QoS) and deterministic behavior with a guaranteed dedicated bandwidth. This avionic data network was first used in the Airbus A380 and A400M. Airbus and Boeing will extend the usage of AFDX in future developments.
