Abstract

This document describes a simple client/server model for supporting policy control over QoS signaling protocols. The model does not make any assumptions about the methods of the policy server, but is based on the server returning decisions to policy requests. The model is designed to be extensible so that other kinds of policy clients may be supported in the future. However, this document makes no claims that it is the only or the preferred approach for enforcing future types of policies.
