Title : NEMO Route Optimisation Problem Statement

The NEMO working group has developed a protocol suite, extending the
notion of edge-mobility on the Internet to include that of network
mobility. This implies that a set of nodes, along with their mobile
router, change their point of attachment and that traffic to these
nodes is tunneled to be delivered through their new point of
attachment. This mechanism is transparent to applications in that
existing traffic to a node is being encapsulated and tunneled,
regardless of where the network containing the destination node is
attached.
The NEMO specification is not limited to a single level of mobile
networks, attaching to the stationary Internet. Rather, arbitrary
levels of nested mobile networks are supported, employing for each
level of nesting the same encapsulation and tunneling mechanisms.
With arbitrarily deep nested mobile networks, the overhead incurred
through tunneling and encapsulation of data traffic can, however,
become large. As a consequence, a number of different proposals
exist, which aim at performing "route optimization" for nested mobile
networks.
This document aims at describing the different scenarios in which
route-optimization is desired, as well as the different proposed
solutions for achieving route-optimization in nested mobile networks.

NOTE: The mail server at ietf.org can return the document in
MIME-encoded form by using the "mpack" utility. To use this
feature, insert the command "ENCODING mime" before the "FILE"
command. To decode the response(s), you will need "munpack" or
a MIME-compliant mail reader. Different MIME-compliant mail readers
exhibit different behavior, especially when dealing with
"multipart" MIME messages (i.e. documents which have been split
up into multiple messages), so check your local documentation on
how to manipulate these messages.
Below is the data which will enable a MIME compliant mail reader
implementation to automatically retrieve the ASCII version of the
