AFDX

AFDX (Avionics Full Duplex Switched Ethernet) is an avionics data network based on commercial 10/100Mbit switched Ethernet. AFDX uses a special protocol to provide deterministic timing and redundancy management providing secure and reliable communications of critical and non-critical data. AFDX communication protocols have been derived from commercial standards (IEEE802.3 Ethernet MAC addressing, Internet Protocol IP, User Datagram UDP) to achieve the required deterministic behavior for avionics applications. End Systems (or LRU's) communicate based on Virtual Links (VL's) with Traffic Shaping by use of Bandwidth Allocation Gaps (BAGs). AFDX Switches incorporate functions for filtering and policing, switching (based on configuration tables), end-system and network monitoring.

The main elements of an AFDX network are:

• AFDX End Systems
• AFDX Switches
• AFDX Links

AFDX data communications are used on the Airbus A380/A350/A400M, Boeing B787 Dreamliner (ARINC664), ARJ21 and Super jet 100. AFDX & ARINC664 is being used as the backbone for all systems including flight controls, cockpit avionics, air-conditioning, power utilities, fuel systems, landing gear and others. The first flight of the Airbus Industries A380 in Toulouse on April 27, 2005 is a real testimony for the programme and a major milestone with the 'first-to-fly' with AFDX on-board based on the commercial 100Mbit/s switched Ethernet (wire) with deterministic behavior.
