What is AFDX?

 

AFDX is comprised of:

  • Avionics Full-Duplex Switched Ethernet (AFDX)
  • ARINC 664 Aircraft Data Network, Part 7
  • Flight Worthy Ethernet

 

AFDX is a deterministic, redundant data network protocol for safety critical applications.
Like Ethernet, AFDX offers:

  • High bandwidth
  • Growth
  • Scalability

Based on IEEE 802.3 Ethernet technology, AFDX utilizes commercial off-the-shelf (COTS) components and is Part 7 of the ARINC 664 Specification which defines how Commercial Off-the-Shelf networking components will be used for future generation Aircraft Data Networks (ADN).

The six primary aspects of AFDX include:

  • Full duplex
  • Redundancy
  • Deterministic
  • High speed performance
  • Switched
  • Profiled network

AFDX adopted concepts from the telecom standard, Asynchronous Transfer Mode (ATM) to fix the shortcomings of IEEE 802.3 Ethernet. By adding key elements from Asynchronous Transfer Mode to those already found in Ethernet, a highly reliable Full-Duplex deterministic network is created providing guaranteed bandwidth and Quality of Service.
