Title : A Taxonomy and Analysis of Enhancements to Mobile IPv6 Route Optimization

IP mobility support typically implies that packets incur lengthened
routing paths by virtue of them being sent through a stationary home
agent. However, "route optimization" in the Mobile IPv6 protocol
enables normal and direct routing between a mobile node and its
correspondent node. To securely allow this feature between initially
unacquainted parties, the so-called return-routability procedure was
built into Mobile IPv6. Recently, a number of improvements or
optional alternatives have been suggested to the standard procedure.
This document summarizes the goals for enhancements to route
optimization, discusses the security threats that such enhancements
must consider, categorizes the techniques that one can use for
optimization, highlights the key ideas of various recent proposals,
evaluates the performance gain that such proposals can yield, and
compares these to ongoing optimization work in other parts of the
network stack. Finally, the paper identifies needs for additional
research.

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
