The service is based on standard IEEE Further a redundant pair of networks is used to improve the system integrity although a virtual link may be configured to use one or the other network only. Multiple switches can be bridged together in a cascaded star topology. However, some features of a real AFDX switch may be missing, such as traffic policing and redundancy functions. AFDX was designed as the next-generation aircraft data network.

Archived copy as title All Wikipedia articles ewitch clarification Wikipedia articles needing clarification from September However, the number sub-VLs that may be created in a single virtual link is limited to four.

In case you wish to receive additional information, send an e-mail to products tttech. Each switch has filtering, policing, and forwarding functions that should be able to process at least VLs. The switches are designed to route an incoming frame from one, and only one, end system to a predetermined set of end systems.


Ethernet family of local area network switcn. By clicking “Download” or “Download without registration” you agree to our Privacy Policy. It utilizes dedicated bandwidth-regulated traffic control while providing deterministic Quality of Service QoS.

This high-performance port switch is certifiable to civil aerospace standards and supports bandwidth-regulated traffic filtering and policing. Additionally, there can be sub-virtual links sub-VLs that are designed to carry less critical data. It specifies interoperable functional elements at the following OSI reference model layers:.

Swittch ADN operates without the use of a bus controller thereby increasing the reliability of the network architecture.

AFDX Switch A Pro This high-performance port switch is certifiable to civil aerospace standards and supports bandwidth-regulated traffic filtering swihch policing.

AFDX is a worldwide registered trademark by Airbus. AFDX Switch Lab This product provides the full range of technical functionalities of our certifiable production switches making it the optimal solution for various applications.

There is no specified limit to the number of virtual links that can be handled by each end system, although this will be determined by the BAG rates and maximum frame size specified for each VL versus the Ethernet data rate. Data are read in a round-robin sequence among the virtual links with data to transmit. There are two speeds of transmission: Office for Harmonization in the Internal Market.

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. Virtual links are unidirectional logic afxd from the source end-system to all of the destination end-systems.


However, total bandwidth cannot exceed the maximum available bandwidth on the network.

DDW: AFDX® / ARINC Part 7 Switch for Flight Test

There can be one or more receiving end systems connected within each virtual link. The architecture adopted by AgustaWestland is centered around the AFDX data network developed for the latest commercial airliners. To get access to the document please fill in the following form.

AFDX was developed by Airbus Industries for the A, [3] initially to address real-time issues for flight-by-wire system development. Therefore, in a network with multiple ardx cascaded star topologythe total number of virtual links is nearly limitless.

TTTech AFDX Switch » TechSAT

By adding key elements from ATM to those already found in Ethernet, and constraining the specification of various options, a highly reliable full-duplex deterministic network is created providing guaranteed bandwidth and quality of service QoS. Innovating together for the A XWB”. Webarchive template wayback links CS1 maint: The drawback is that it requires custom hardware which can add significant cost to the aircraft.

Many commercial aircraft use the ARINC standard developed in for safety-critical applications. This is the maximum rate data can be sent, and it is guaranteed to be sent at that interval. Archived from the ewitch PDF on This type of network can significantly reduce wire runs and, thus, the overall weight of the aircraft.
