   Transmission of IPv6 Packets over Aeronautical ("aero") Interfaces
                draft-templin-atn-aero-interface-07.txt

Abstract

   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.
   Mobile nodes connect to access networks using either the classic or
   mobility service-enabled link model.  This document specifies the
   transmission of IPv6 packets over aeronautical ("aero") interfaces.

1.  Introduction

   Mobile Nodes (MNs) such as aircraft of various configurations may
   have multiple data links for communicating with networked
   correspondents.  These data links often 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 the
