Abstract
This document describes the use of the Common Open Policy Service
(COPS) protocol for support of policy provisioning (COPS-PR). This
specification is independent of the type of policy being provisioned
(QoS, Security, etc.) but focuses on the mechanisms and conventions
used to communicate provisioned information between PDPs and PEPs.
The protocol extensions described in this document do not make any
assumptions about the policy data model being communicated, but
describe the message formats and objects that carry the modeled
policy data.
