Avionics Full-Duplex Switched Ethernet (AFDX), also ARINC 664, is a data network, patented by international aircraft manufacturer Airbus, [1] for safety-critical applications that utilizes dedicated bandwidth while providing deterministic quality of service (QoS).
This equipment, when installed in a network topology, can provide effective data transfer and overall avionics performance. The ARINC 664 specification refers extensively to the set of data networking standards developed by the Internet community and IEEE. The specification also applies the concepts of Open Systems Interconnection (OSI) standards.
ARINC 615A is a standard that covers a "data loading" protocol which can be used over various bus types such as Ethernet, CAN, and ARINC 664. ARINC 618 is a standard that covers a data transmission protocol called "Character Oriented Protocol". ARINC 619 is a standard that covers a data transmission protocol over ARINC 429 called "Bit Oriented ...
Communication between the modules can use an internal high speed Computer bus, or can share an external network, such as ARINC 429 or ARINC 664 (part 7). However, much complexity is added to the systems, which thus require novel design and verification approaches since applications with different criticality levels share hardware and software ...
ARINC 629 defines a high-speed, multi-transmitter, TDMA extension to ARINC 429, superseded by AFDX. ARINC 664.7 defines the use of a deterministic Ethernet network as an avionic databus in later aircraft like the Airbus A380 and the Boeing 787. This standard defines virtual point-to-point connections implementing the same concept as used in ...

As the article specifies, AFDX is specified in one of the 7 or 8 sections of the ARINC 664 specification. A broad generalization of AFDX is that it is a redundant form of ARINC 664. Based on this, it seems the article should be specifically about ARINC 664 and another page should be created to detail the AFDX section. anonymous 21-Feb-2011
