	Title		: Experimental Handoff Extension to RADIUS
	Author(s)	: W. Arbaugh, B. Aboba

In order to decrease handoff latency, the concept of pre-emptive
provisioning is under investigation.  This document describes an
experimental extension that enables an accounting server to notify a NAS
of a prospective handoff.  This enables the NAS to reserve resources and
obtain the session parameters prior to arrival of the client,
potentially reducing handoff times.  The extension described in this
document may potentially be useful in enabling handoffs across access
technologies and providers. However, whether the approach described in
this document is effective, deployable or secure is the subject of
current research.  It is offered for RADIUS primarily because source
code for RADIUS client and server implementations is readily available
for research purposes.  Given that this extension represents research
work in progress, implementation of this specification for purposes
other than research is not recommended.

In the body type:

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.
