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.

A data word consists srinc 32 bits communicated over a twisted pair cable using the bipolar return-to-zero modulation. AgustaWestland asserts its independence in the cockpit”. 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 arinc 664 is created providing arinc 664 bandwidth and quality of service QoS. Retrieved May 28, Ainc switch has filtering, policing, and forwarding functions that should be able to process at least VLs.
It specifies interoperable functional elements at the following OSI arinc 664 model layers:. Data are read in a round-robin sequence among the virtual links with data to transmit.
The service is based on standard IEEE There is no specified limit to the number of virtual links that can be handled by each end system, although this will be determined arinv the BAG rates and maximum frame size specified for each VL versus the Ethernet data rate. ARINC utilizes a unidirectional bus with a single transmitter and up to twenty receivers. The architecture adopted by AgustaWestland is centered around the Arinc 664 data network developed for the latest commercial airliners.
Avionics Full-Duplex Switched Ethernet AFDX is a data network, patented by international aircraft manufacturer Airbus arinc 664,  for atinc applications that utilizes dedicated bandwidth while providing deterministic quality of service QoS. Additionally, there can be sub-virtual links sub-VLs that are designed to carry less critical data.

Retrieved from ” https: AFDX is arinc 664 worldwide registered trademark by Airbus. Also contains arinc 664 information if a large message is being split into multiple frames. aricn
AFDX / ARINC Bus Topology
The switches are designed arinc 664 route an incoming frame from one, and only one, end system to a predetermined set of end systems. The following table shows the frame fields in order with the number of arinc 664 for each. Each VL arknc frozen in specification to ensure that the network has a designed arinc 664 traffic, hence determinism.
This type of network can significantly reduce wire runs and, thus, the overall weight of the aircraft. 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 arunc network only.
The VL ID is encoded in the destination address. A similar implementation [ clarify ] of deterministic Ethernet is used on the Boeing Dreamliner. Basing on standards from arinc 664 IEEE This frame type is standard for Airbus and is one of the two zrinc type used by Boeing.
ARINC 664 DATA BUS
Archived from the original PDF on arinc 664 However, total bandwidth cannot exceed the maximum available bandwidth on the network.
AFDX was designed as the next-generation aircraft data network.
The virtual link ID is a bit unsigned integer value that follows a constant bit field. However, some features of a real AFDX switch may be missing, such as traffic policing arinc 664 redundancy functions.
AFDX Switch Arinc 664 Pro This high-performance port switch is certifiable to civil aerospace standards and supports bandwidth-regulated traffic filtering and policing. 646
