With current Network Mobility (NEMO) Basic Support, all
communications to and from Mobile Network Nodes must go through the
bi-directional tunnel established between the Mobile Router and Home
Agent when the mobile network is away.  This sub-optimal routing
results in various inefficiencies associated with packet delivery,
such as increased delay and bottleneck links leading to traffic
congestion, which can ultimately disrupt all communications to and
from the Mobile Network Nodes.  Additionally, with nesting of Mobile
Networks, these inefficiencies get compounded, and stalemate
conditions may occur in specific dispositions.  This document
investigates such problems and provides the motivation behind Route
Optimization (RO) for NEMO.  This memo provides information for the 
Internet community.

This document is a product of the Network Mobility
Working Group of the IETF.
