The ARINC is a deterministic avionics data network based on commercial 10 /Mbit switched Ethernet which provides deterministic timing and. The ARINC message format is based on the standard Ethernet frame. This frame type is standard for Airbus and is one of the two frame type used by Boeing . AIT’s ARINC test instruments can be used in test and simulation applications that are required to transmit and receive data over the ARINC avionics.

Avionics Full-Duplex Switched Ethernet

The network is designed in such a way that all critical traffic is prioritized using QoS policies so delivery, latency, and jitter are all guaranteed to be within set parameters. Avionics Full-Duplex Switched Ethernet AFDX 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.

From Wikipedia, the arinc 664 encyclopedia. Also the switch, having a Arinc 664 configuration table loaded, can reject any erroneous data transmission that may otherwise swamp other branches of the network. Through the use of twisted pair or fiber optic cables, full-duplex Ethernet uses arinc 664 separate pairs or strands for transmitting and receiving the data. Virtual links are unidirectional logic paths from the source arinc 664 to all of the destination end-systems. In one abstraction, it is possible to visualise the VLs as an ARINC style network each with one source and one or arinc 664 destinations.


AFDX was developed by Airbus Industries for the A, [3] initially to address real-time arinc 664 for flight-by-wire system development. Contains the destination End System Identification. The Sequence Numbers on successive frames must be in order. Further a redundant pair of arinc 664 is used to improve the system integrity although a virtual link may be configured to use one or the other network only.

AFDX is arinc 664 worldwide registered trademark by Airbus. Multiple switches 66 be bridged together in a cascaded star topology. However, total bandwidth cannot exceed the maximum available bandwidth on the network. This makes them more bandwidth efficient and more widely used. arinc 664

Bi-directional communications must therefore require the specification of a complementary VL. Also arinc 664 fragmentation information if a large message is being split into multiple atinc.

The drawback is that it requires custom hardware which can add significant cost to the aircraft. Webarchive template wayback links All Wikipedia articles needing clarification Wikipedia articles needing clarification from September This is the maximum rate data can be sent, and it is guaranteed to be sent at that interval. This page was last edited on 7 Juneat A limited number of data types are defined for implicit messages and are listed below.

Wrinc together for the A Arinc 664. It specifies interoperable arinc 664 elements at the following OSI reference model layers:. Arjnc virtual link ID is a bit unsigned integer value that follows a constant bit field. Arinc 664 utilizes a unidirectional bus with a single transmitter and up to twenty receivers.


Each VL is frozen in arinc 664 to ensure that arinc 664 network afinc a designed maximum traffic, hence determinism. AFDX Switch A Pro This high-performance port switch is certifiable to civil aerospace standards and supports bandwidth-regulated traffic filtering and policing.

This frame include a supplemental layer arinc 664 the EDE layer used for enhanced control, checking and time validation of the frame. There are two speeds of transmission: By adding key elements from ATM to those already found in Ethernet, and constraining arinc 664 specification of various options, a highly 66 full-duplex deterministic network is created providing guaranteed bandwidth and quality of service QoS.
