Transmission of IPv6 Packets over Aeronautical ("aero") Interfaces
draft-templin-atn-aero-interface-06.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
