RE: Client-Server Model of COPS

["Fenger, Russell J" <russell.j.fenger@intel.com>]

I'm cross-posting this to the RAP list for further discussion.

If you are using COPS-PR, then what you've described sounds like
it is covered in the accounting framework pib:
http://www.ietf.org/internet-drafts/draft-rawlins-acct-fr-pib-00.txt

This document describes how Report messages are used to send usage
related data to the PDP.  I assume that this information could be
used by the PDP to adjust the decisions previously sent.
