The Mobile IPv6 mobility-management protocol enables minimum routing
paths between a mobile node and a correspondent node, which may
itself be mobile. This feature is called route optimization. Route
optimization requires authorization of initially unacquainted and
untrusted parties. A so-called return-routability procedure was
integrated into the Mobile IPv6 in order to do this securely. The
return-routability procedure equips the mobile node with
cryptographic tokens that authenticate the mobile node and prove the
mobile node's presence at a claimed new location after movement.
Recently, a number of improvements or optional alternatives have been
suggested to the standard procedure. The primary driver between these
improvements is oftentimes further reduction of signaling messages
and latency, but other improvements such as better security have also
been suggested. This document discusses the potential goals for
future enhancements of route optimization, the security threats that
such enhancements must consider, and the various enhancement
proposals and their key ideas. An evaluation of some recent proposals
is included, as well as a discussion of how significant the Mobile
IPv6 related optimizations are related to other ongoing optimization
efforts. Finally, needs for future research are outlined.

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
