PURPOSE AND SCOPE

Introduction

This document contains the technical Profiles of the Internet Engineering Task Force (IETF) Request for Comments (RFC) series of documents addressing relevant Application, Transport, Network, Addressing and Naming, Security, Mobility, and Multi-link communication functions for the Internet Protocol Suite (IPS). These Profiles specify characteristics that should be useful to designers, installers, manufacturers, service providers and users for IPS systems intended for operational use within the United States National Airspace System (NAS) and the European Airspace. Where systems are global in nature, the system may have international applications which are taken into consideration.

Compliance with these Profiles will be mandated through the regulatory process to assure that the system and each subsystem will perform its intended function(s) satisfactorily under conditions normally encountered in routine aeronautical operations for the environments intended. The Profiles may be implemented by one or more regulatory documents and/or advisory documents (e.g., certifications, authorizations, approvals, commissioning, advisory circulars, notices, etc.) and may be implemented in part or in total. Any regulatory application of this document is the sole responsibility of appropriate governmental agencies.

Section 2.0 of this document describes the IPS and provides information needed to understand the rationale for system characteristics and requirements which are stated by IPS comprising the Transport, Network, Addressing and Naming, Security, Mobility, Multi-link, Network Management and System Interfaces. It describes typical application use cases and concept of operations, as envisioned by members of RTCA Special Committee - 223 and EUROCAE Working Group - 108 and establishes the basis for the Profiles stated in the following sections. Definitions and assumptions essential to proper understanding of this document are also provided in this section.

Section 3.0 of this document specifies the high-level functional requirements for each of the major IPS functions followed by references to Appendix A that identifies IPS profile tables by IPS Device Classes for each IETF RFC related to those functions. The IPS Device Classes are described in Table 1-2.

RTCA and EUROCAE acknowledge that all content reproduced from the RFCs are the intellectual property of IETF and have coordinated with IETF on their inclusion in this document. All IETF legends, legal notices and indications of authorship contained in the original IETF RFC are still in force. As per the request of the IEFT Trust, where more than one-fifth of such text is reproduced in RTCA/EUROCAE joint documents, all legends, legal notices and indications of authorship are reproduced in the RTCA/EUROCAE documents. For all RFCs discussed in appendix B, this information is included even if less than 1/5^th of the RFC is included in this document.

Appendix D contains the complete list of RFCs mentioned in this document with hyperlinks to the IETF site to aide their use by the reader.

The word "subsystem" as used in this document includes all components that make up a major independent, necessary and essential functional part of the system so that the system can properly perform its intended function(s). If the system, including any subsystem, includes computer software, the guidelines contained in RTCA/DO-178() /EUROCAE ED-12() should be considered for airborne applications and other applicable standards for non-airborne applications.
