                 Policy-Based Management Framework for
            the Simplified Use of Policy Abstractions (SUPA)

Abstract

   The Simplified Use of Policy Abstractions (SUPA) policy-based
   management framework defines base YANG data models to encode policy.
   These models point to device-, technology-, and service-specific YANG
   data models developed elsewhere.  Policy rules within an operator's
   environment can be used to express high-level, possibly network-wide,
   policies to a network management function (within a controller, an
   orchestrator, or a network element).  The network management function
   can then control the configuration and/or monitoring of network
   elements and services.  This document describes the SUPA basic
   framework, its elements, and interfaces.

1.  Introduction

   Traffic flows over increasingly complex enterprise and service
   provider networks are becoming more and more important.  Meanwhile,
   the rapid growth of this variety makes the task of network operations
   and management applications deploying new services much more
   difficult.  Moreover, network operators want to deploy new services
   quickly and efficiently.  Two possible mechanisms for dealing with
