Abstract

   RSVP [RFC 2205] signaling messages typically include policy data
   objects, which in turn contain policy elements. Policy elements may
   describe user and/or application information, which may be used by
   RSVP aware network elements to apply appropriate policy decisions to
   a traffic flow. This memo details the usage of policy elements that
   provide application information.

1. Overview

   RSVP aware network elements may act as policy enforcement points
   (PEPs). These work together with policy decision points (PDPs) to
   enforce QoS policy. Briefly, PEPs extract policy information from
   RSVP signaling requests and compare the information against
   information stored by a PDP in a (possibly remotely located) policy
   database or directory. A policy decision is made based on the results
   of the comparison.
