	Title		: Session Authorization for RSVP

This document describes the representation of session authorization
information in the POLICY_DATA object [POL-EXT] for supporting
policy-based per-session authorization and admission control in
RSVP.  The goal of session authorization is to allow the exchange
of information between network elements in order to authorize the
use of resources for a service and to co-ordinate actions between
the signaling and transport planes.  This document describes how a
process on a system authorizes the reservation of resources by a
host and then provides that host with a session authorization
policy element which can be inserted into the RSVP PATH message to
facilitate proper and secure reservation of those resources within
the network. We describe the encoding of media authorization
information as RSVP policy elements and provide details relating to
operations, processing rules and error scenarios.

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.
