   Transmission of IPv6 Packets over Aeronautical ("aero") Interfaces
                  draft-templin-atn-aero-interface-10

Abstract

   Aeronautical mobile nodes (e.g., aircraft of various configurations)
   communicate with networked correspondents over multiple access
   network data links and configure mobile routers to connect their on-
   board networks.  An Air-to-Ground (A/G) interface specification is
   therefore needed for coordination with the ground domain network.
   This document specifies the transmission of IPv6 packets over
   aeronautical ("aero") interfaces.

1.  Introduction

   Aeronautical Mobile Nodes (MNs) such as aircraft of various
   configurations often have multiple data links for communicating with
   networked correspondents.  These data links may have differing
   performance, cost and availability characteristics that can change
   dynamically according to mobility patterns, flight phases, proximity
   to infrastructure, etc.

   Each MN receives an IPv6 Mobile Network Prefix (MNP) that can be used
   by on-board networks independently of the access network data links
   selected for data transport.  The MN performs router discovery (i.e.,
   similar to IPv6 customer edge routers [RFC7084]) and acts as a mobile
