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.
