Transmission of IPv6 Packets over Aeronautical ("aero") Interfaces
draft-templin-atn-aero-interface-02.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 configure a virtual interface (termed the "aero
interface") as a thin layer over their underlying data link
interfaces. 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 regardless of the actual link or links selected
for data transport. The MN performs router discovery the same as for
customer edge routers [RFC7084], and acts as a mobile router on
behalf of its on-board networks. A virtual interface (termed the
"aero interface") is configured as a thin layer over the underlying
access network data link interfaces.
The aero interface is therefore the only interface abstraction
exposed to the IPv6 layer and behaves according to the Non-Broadcast,
Multiple Access (NBMA) interface principle, while underlying access
