COPS - Common Open Policy Services

COPS is a mechanism which allows endpoints to negotiate with networks for resources based on pre-agreed policy. COPS uses two basic elements to control which resources the subscriber receives, namely the PDF (Policy Decision Function) and the PEF (Policy Enforcement Function). The PDF holds subscriber information and will notify the PEF as to whether or not a subscriber should be allowed the requested resources.
