1.  Introduction

   This document defines a base YANG [RFC6020] data module for Quality
   of Service (QoS) configuration and operational parameters.
   Differentiated Services (DiffServ) module is an augmentation of the
   base QoS model.  Remote Procedure Calls (RPC) or notification
   definition is currently not part of this document and will be added
   later if necessary.  QoS base modules define a basic building blocks
   to define a classifier, policy, action and target.  The base modules
   have been augmented to include packet match fields, action
   parameters, and statistics data to define the DiffServ module.  It is
   left up to individual vendors to stitch actions like queues, random-
   detect (RED) and vendor specific parameters of the DiffServ policy
   definitions.  Designing the module in this manner allows for a very
   flexible and extensible module that should fit in with most of the
