A policy architecture and framework is discussed to support NFV environments, where policies are used to enforce business rules and to specify resource constraints in a number of subsystems. This document approaches the policy framework and architecture from the perspective of overall orchestration requirements for services involving multiple subsystems. The analysis extends beyond common orchestration constraints across compute, network, and storage subsystems to also include energy conservation constraints. This document also analyses policy scope, global versus local policies, policy actions and translations, policy conflict detection and resolution, interactions among policies engines, and a hierarchical policy architecture/framework to address the demanding and growing requirements of NFV environments, that could also be applicable to cloud infrastructures in general.
