1 Introduction

   Policy usage reported by the PEP makes a richer set of information
   available to the PDP for decision-making.  This feedback on policy
   usage can impact future decisions made by the PDP and the resulting
   policy installed by the PDP at the PEP.  For example, a PDP making
   policy for a SIP signaled multimedia session may need to base the
   decision in part on usage information related to previously installed
   QoS policy decisions.  Furthermore, the PDP may coordinate this usage
   information with other external systems to determine the future
   policy such as the case with the PDP coordinating multimedia session
   QoS and clearinghouse authorizations [SIP-AAA-QOS].
