Aircraft Data Network (ADN), as defined in the Airlines Electronic Engineering Committee (AEEC)'s ARINC 664 specification, is a standardized approach to data networking within commercial aircraft. The specification adapts commercial off-the-shelf networking standards, like those used in everyday computers and the internet, to meet the specific requirements of aviation. ARINC 664 details how common networking devices—such as bridges, switches, routers, and hubs—can be used within an aircraft's network to ensure reliable and efficient data transfer between avionics systems. This specification leverages established internet and IEEE networking standards and is based on the Open Systems Interconnection (OSI) model, providing a framework for interoperability between different aircraft systems.
Structure The specification is organized in multiple parts, as follows:
Part 1 – Systems Concepts and Overview Part 2 – Ethernet Physical and Data-Link Layer Specifications Part 3 – Internet-based Protocols and Services Part 4 – Internet-based Address Structure and Assigned Numbers Part 5 – Network Domain Characteristics and Functional Elements Part 6 – Reserved; Part 7 – Deterministic Networks Part 8 – Upper Layer Protocol Services
