Summary

Introduction

The OOF retrieves applicable constraints and objective functions as policies from the policy platform. These policies are retrieved at runtime, thus allowing an operator to change policies as and when needed. These policies are specified using available policy models in the policy platform. The OOF-related policy models are typically generated from models specified by VNF vendors, service designers, and site administrators. Currently, for R2, these models will be pushed into the policy platform manually using the OOF policy uploader module.

Policy Platform

The OOF relies on the following features of the policy platform: (a) policy specification (typically based on policy models for constraints and objectives), (b) policy prioritization (typically for the same policy name, each with different priorities), and (c) querying of policies based on different criteria (e.g. by scope, by name patterns, etc.)
