There are two speeds of transmission: Each switch has filtering, policing, and forwarding functions that should be able to process at least VLs.

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, the number sub-VLs that may be created in a single virtual link is limited ztandard four. AFDX was designed as the next-generation aircraft data network.

Office for Harmonization in the Internal Market. Archived copy as title All Wikipedia articles needing clarification Wikipedia articles needing clarification from September The drawback is that it requires custom hardware which can add significant cost to the aircraft. Retrieved from ” https: Also the switch, having a VL configuration table loaded, can reject any erroneous data transmission that may otherwise swamp other branches of the network.

This ADN operates without the use of a bus controller thereby increasing the reliability of the network architecture. Therefore, in a network with multiple switches cascaded star topologythe total staneard of virtual links is nearly limitless. Virtual links are unidirectional logic paths from the source end-system to all of the destination end-systems. This is the maximum rate data can be sent, and it is guaranteed to be sent at that interval.

Sub-virtual links are assigned to a particular virtual link. Archived from the original PDF on Additionally, there can be sub-virtual links sub-VLs that are designed to carry less arknc data. Each virtual link is allocated dedicated bandwidth [sum of all VL bandwidth allocation gap BAG rates x MTU] with the total amount of bandwidth defined by the system integrator.

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

However, some features of a real AFDX switch may be missing, such as traffic policing and redundancy functions. AgustaWestland asserts its independence in the cockpit”.

Real-time 64 on the Stadard PDF. 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.

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.

From Wikipedia, the free encyclopedia. It specifies interoperable functional elements at the following OSI reference model layers:.

Avionics Full-Duplex Switched Ethernet – Wikipedia

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.

ARINC utilizes a unidirectional bus with a single transmitter and up to twenty receivers. 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. Basing on standards from the IEEE Each VL is frozen in specification to ensure that the network has a designed maximum traffic, hence determinism.

Webarchive template wayback links CS1 maint: There can be one or more receiving end systems connected within each virtual link.

In one abstraction, it is possible to visualise the VLs as an ARINC style network each with one source and one or more destinations. Retrieved May 28, In addition, AFDX can provide quality of service and dual link redundancy.
