scope:

This document, the Structure of Policy Provisioning Information (SPPI), defines the adapted subset of SNMP's Structure of Management Information (SMI) used to write Policy Information Base (PIB) modules.

RFC 2748 defines the COPS protocol, and RFC 2749 describes how the COPS protocol is used to provide for the outsourcing of policy decisions for RSVP. Another usage of the COPS protocol, for the provisioning of policy, is introduced in RFC 3084. In this provisioning model, the policy information is viewed as a collection of Provisioning Classes (PRCs) and Provisioning Instances (PRIs) residing in a virtual information store, termed the Policy Information Base (PIB). Collections of related Provisioning Classes are defined in a PIB module.
