                 SUPA Policy-based Management Framework
          draft-ietf-supa-policy-based-management-framework-03

Abstract

   Simplified Use of Policy Abstractions (SUPA) defines base YANG data
   models to encode policy, which point to device-, technology-, and
   service-specific YANG 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 become more and more important.  Meanwhile, the
   rapid growth of the 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 this growing
   difficulty are the use of software abstractions to simplify the
