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.
This standard manualdefines contains the minimum communication protocols and services that will enable implementation of an ICAOn Aeronautical Telecommunication Network (ATN) based on theICAO-approved Internet Protocol Suite (IPS) utilizing Internet Protocol version 6 -based Aeronautical Telecommunication Network (ATN) (IPv6). Thisese protocols and services will enable interoperation with both ISO OSI standards from ISO/IEC and ITU-T as well asand IPv4 based network technologies as used in the current ATN infrastructureimplementations. The approach herein documents the minimum required protocols and services that will enable a global ATN IPS. Implementation of IPv4 for transition (or as a permanent subnetwork) is a regional or local issue, and will not be addressed in this documentmanual. The scope of the manualDRAFT - ICAO ATN Manual of Detailed Technical Specification for Internet Protocol Suite (IPS) is purelyon inter-domain routing, although the material in this manual can also be used for intra-domain routing (e.g. within a country).
The standards protocol structure for the ATN IPS architecture is shownThe IPS in the ATN architecture is illustrated in Figure 1.

Specified in this document areIn accordance with Annex 10, Volume III, Part I, paragraph [3.3.3] implementation of the ATN, including the protocols and services included in this manual, shall take place on the basis of that shall be implemented by rRegional aAir Nnavigation agreements between ICAO contracting states. . Regional planning and implementation groups (PIRG’s) are coordinating such agreements.
This section specifies general requirements for implementing the ATN IPS in the ATN. Figure 2 depicts the ATN IPS protocol suite.
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.
