The scope of this specification is to define the addressing plan and rules used for the ADN using this specification.

The communication services of the ADN are organized into seven layers as defined by the Open Systems Interconnection (OSI) Reference Model. There are several places within these layers where addresses or, more generally, identifiers are used. This specification provides rules and plans for the ADN for appropriate layers defined by the OSI Model.

This specification is a part of the ARINC Specification 664 series. Hence, system considerations and other electrical related topics may be found in other parts of this series.

Purpose of Document

The purpose of this specification is to provide guidance in the determination of all addresses that are needed in the Aircraft Data Network (ADN). This will ensure that all applications that send messages know the addresses of the destinations at "configuration-time."
