This document defines the requisite data communications protocols and services to be used for implementing the International Civil Aviation Organization (ICAO) Aeronautical Telecommunications Network (ATN) using the Internet Protocol Suite (IPS). The material in this document is to be considered in conjunction with the relevant Standards and Recommended Practices (SARPs) as contained in Annex 10, Volume III, Part I Chapter 3.

With regard to the implementation of the ATN applications, it should be noted that it is preferred that such applications be developed as a native ATN/IPS application. However, in the absence of such material, applications developed for the ATN/OSI network can be implemented over a TCP/IP (IPS) network, using RFC 1006 as an OSI to IPS convergence function.
