AFDX (ARINC 664) Testing Guide

This guide explains the parts of ARINC 664 Part 7 (AFDX) that matter when you test it, and what to check when choosing a test interface. It cites the ARINC standard description and manufacturer pages.

What AFDX is

• A deterministic switched Ethernet network for avionics defined in ARINC 664 Part 7; AFDX is an Airbus trademark ^[1].
• It covers MAC and VL addressing, IP/ICMP, UDP with optional TCP, and sampling, queuing, SAP, TFTP and SNMP services ^[2].

Key concepts for testing

• Virtual Links with a bandwidth allocation gap (BAG) and sub-VLs ^[3].
• Dual-redundant networks A and B ^[3].
• Sampling ports keep the latest value; queuing ports keep every message ^[2].

Choosing an interface

• Simulation, monitoring or both, and how many ports you need ^[3].
• Bandwidth and form factor, e.g. 1 Gbit/s on PCIe or XMC ^[4].
• Whether you also need SAE AS6802 time-triggered traffic ^[4].
• Software tools and APIs ^[3][5].

Limits

• Interface manuals do not replace aircraft or component maintenance data.

Frequently asked questions

Does an AFDX card need export review?

Often yes; Novatelia checks export and end-use requirements with the OEM channel before quoting.

Is ARINC 429 still used with AFDX?

Yes, many aircraft use both; see our ARINC 429 test equipment category.

This guide is general information. It does not replace the aircraft maintenance manual, the operator's approved procedures or the rules of the competent civil aviation authority.
