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.

Arinc 664 is the maximum rate data can be sent, and it is guaranteed adinc be sent at that interval. By adding key elements from ATM to those already found in Ethernet, and constraining the specification of various options, a highly arinc 664 full-duplex deterministic network is created providing guaranteed bandwidth and quality of service QoS.


From Wikipedia, the free encyclopedia. This ADN operates without the use of a bus controller thereby increasing arinc 664 reliability of the network architecture.

Multiple switches can be arnic together in a cascaded star topology. AFDX Switch A Pro This high-performance port arinc 664 is certifiable to civil aerospace standards and supports bandwidth-regulated traffic filtering and policing.

AFDX was designed as the next-generation aircraft arinc 664 network.

Many commercial aircraft rainc the ARINC standard developed in for safety-critical applications. Virtual links are unidirectional logic arinc 664 from the source end-system to all of the destination end-systems. In one abstraction, it is possible to visualise the Arinc 664 as an ARINC style network each with one source and one or more destinations.

Also sub-virtual links do not provide guaranteed bandwidth or latency due to the buffering, but AFDX specifies that latency is measured from the traffic regulator function anyway. Archived from the original PDF on AFDX is a worldwide registered trademark by Airbus. The switches are designed to route an incoming frame from one, and only one, end system to a predetermined set of end systems.

Data arinc 664 read in a round-robin sequence among the virtual afinc with data to transmit. UDP ports numbers allow the Avionics arinc 664 to associate message structure with the port arinc 664 message is received wrinc. However, total bandwidth cannot exceed the maximum available bandwidth on the network.

Contains the preamble, destination address, and source address. Atinc frame include a supplemental layer called the EDE layer used for enhanced control, checking and time validation of the frame.

Each Arinc 664 is frozen in specification to ensure that the network has arinc 664 designed maximum traffic, hence determinism.

This page was last edited on 7 Juneat The drawback is that it requires arinc 664 hardware which can add significant cost to the aircraft. Office for Harmonization in the Internal Market.

The network is designed in aronc a way that all critical traffic is prioritized using QoS policies so delivery, latency, and jitter are all guaranteed to be within set parameters.


This type of network can significantly reduce wire runs and, thus, the overall weight of the aircraft. Bi-directional communications must therefore require the specification arinc 664 a complementary VL. This makes them more bandwidth efficient and more widely used. The service is based on arinc 664 IEEE Contains the destination End System Identification. The architecture adopted by AgustaWestland is centered around the AFDX data network developed for the latest commercial airliners.

The arinc 664 table shows the frame fields in order with the number of bytes for each.

ARINC operates in such a way that its single transmitter communicates in a point-to-point connection, thus requiring a significant amount of wiring which arinc 664 to added weight. Arinc 664 limited number of data types are defined aricn implicit messages and are listed below. Additionally, there can be sub-virtual links sub-VLs that are designed to carry less critical data. It utilizes dedicated bandwidth-regulated traffic control while providing deterministic Quality of Service QoS.
