Title : Access Router Based Movement Detection and CoA
Configuration

This document proposes Access Router (AR) based movement detection
and Care-of Address (CoA) configuration for fast handover in Mobile
IPv6. An Active Access Router (AcAR) which will serve a Mobile Node
(MN) performs movement detection, formulates a new CoA of the MN and
does Duplicate Address Detection (DAD) on behalf of the MN. After
confirming the uniqueness of the new CoA, the AcAR sends it through a
RA message. Since an AcAR can quickly determine the L3 movement by
the comparison between neighbor caches and L2 information of a MN, a
MN does not have to wait to receive RA messages from ARs. Thus, the
movement detection delay is reduced. Since DAD is performed by an
AcAR in advance, a MN does not have to do normal DAD and it can use
the new CoA for its interface directly.

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
