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. A similar implementation [ clarify ] of deterministic Ethernet is used on the Sfdx Dreamliner.

Zfdx, some features of a real AFDX switch may be missing, such as traffic policing and redundancy functions. Retrieved May 28, AFDX extends standard Ethernet to provide high data integrity and deterministic timing. Each switch has filtering, policing, and forwarding functions that should be able to process at least VLs. Sub-virtual links are assigned to a particular virtual link. Multiple switches can be bridged together in a cascaded star topology.

Data are read in a swigch sequence among the virtual links with data to transmit. ARINC utilizes a unidirectional bus with a single transmitter and up to twenty receivers.

AFDX Switch Lab This product provides the full range of technical functionalities of our certifiable production afrx making it the optimal solution for various applications. Saitch, total bandwidth cannot exceed the maximum available bandwidth on the network. The switch must also be non-blocking at the data rates that are specified by the system integrator, and in practice this may mean that the switch shall have a switching capacity that is the sum of all of its physical ports.


Many commercial aircraft use the ARINC standard developed in for safety-critical applications. AFDX is a worldwide registered trademark by Airbus.

This page was last edited on 10 Novemberat The drawback is that it requires custom hardware which can add significant cost to the aircraft. This is the maximum rate data can be sent, and it is guaranteed to be sent at that interval.

It utilizes dedicated bandwidth-regulated traffic control while providing deterministic Affdx of Service QoS. The virtual link ID is a bit unsigned integer value that follows a constant bit field. In addition, AFDX can provide quality of service and dual link redundancy.

Through the use of twisted pair or fiber optic cables, full-duplex Ethernet uses two separate pairs or strands for transmitting and receiving the data.

Therefore, in a network with multiple switches cascaded star topologyafdz total number of virtual links is nearly limitless. The service is based on standard IEEE AFDX Switch A Pro This high-performance port switch is certifiable to civil aerospace standards and supports bandwidth-regulated traffic filtering and policing.


There can be one or more receiving end systems connected within each virtual link. 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.

In case you wish to receive additional information, send an e-mail to products tttech. 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.

Innovating together for the A XWB”. Virtual links are unidirectional logic paths from the source end-system aafdx all of the destination end-systems. This type of network can significantly reduce wire runs and, thus, the overall weight of the aircraft.

Basing on standards from the IEEE This ADN operates without the use of a bus controller thereby increasing the reliability of the network architecture. Archived from the original PDF on 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 amounts to added weight.
