This document approaches the policy framework and architecture from the perspective of overall orchestration requirements for services involving multiple subsystems. The framework extends beyond common orchestration constraints across compute, network, and storage subsystems to include energy conservation. This document also analyses policy scope, global versus local policies, static versus dynamic versus autonomic 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. These findings may also be applicable to cloud infrastructures in general.}, }
