          Network Mobility Route Optimization Requirements for
  Operational Use in Aeronautics and Space Exploration Mobile Networks

Abstract

   This document describes the requirements and desired properties of
   Network Mobility (NEMO) Route Optimization techniques for use in
   global-networked communications systems for aeronautics and space
   exploration.

   Substantial input to these requirements was given by aeronautical
   communications experts outside the IETF, including members of the
   International Civil Aviation Organization (ICAO) and other
   aeronautical communications standards bodies.

1.  Introduction

   As background, the Network Mobility (NEMO) terminology and NEMO goals
   and requirements documents are suggested reading ([4], [5]).

   The base NEMO standard [1] extends Mobile IPv6 [2] for singular
   mobile hosts in order to be used by Mobile Routers (MRs) supporting
   entire mobile networks.  NEMO allows mobile networks to efficiently
   remain reachable via fixed IP address prefixes no matter where they
   relocate within the network topology.  This is accomplished through
   the maintenance of a bidirectional tunnel between a NEMO MR and a
   NEMO-supporting Home Agent (HA) placed at some relatively stable
