Transmission of IPv6 Packets over AERO Interfaces
draft-templin-atn-aero-interface-00.txt
Abstract
Mobile nodes (e.g., aircraft of various configurations) act as mobile
routers for their on-board networks, and may have multiple data links
for communicating with networked correspondents. 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 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 acts as a mobile router on behalf of its
on-board networks, but appears as a multi-addressed host from the
perspective of off-board correspondents. This implies the need for a
virtual interface (termed the "AERO interface") configured as a thin
layer over the underlying 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. This document
specifies the transmission of IPv6 packets [RFC8200] over AERO
