This document describes the representation of a session
authorization policy element for supporting policy-based per-session
authorization and admission control.  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 a resource reservation protocol (e.g., the Resource
ReSerVation Protocol (RSVP) PATH message) to facilitate proper and
secure reservation of those resources within the network.  We describe
the encoding of session authorization information as a policy element
conforming to the format of a Policy Data object (RFC 2750) and
provide details relating to operations, processing rules and error
scenarios.
