ARINC SPECIFICATION 664 PART 1 – Page 4
1.0 INTRODUCTION
Part 8, Interoperation with Non-IP Protocols and Services provides for ATN
applications to communicate over IP.
1.3.3 Part 1, Systems Concepts and Overview
This document is organized into sections that describe the system concept and
provide an overview of Ethernet communication systems as applied to transport
aircraft.
• Section 1.0, Introduction, describes the relationship of Part 1 to other parts of
ARINC Specification 664 and to other relevant standards.
• Section 2.0, Introduction to Network Concepts, presents the fundamental
concepts of data communication networks. The OSI Reference Model, a
comparison of OSI and Internet Based Data Networks and Network
Topologies, is included.
• Section 3.0, Aircraft Data Networks, describes domains and aircraft data
networks, deconstruction of the domains and related concepts.
• Appendix A is a tutorial of network performance and concepts that form the
foundation of Internet communication.
• Appendix B is a glossary of terms.
