1.  Introduction

   This document defines a base YANG [RFC6020] [RFC7950] data module for
   Quality of Service (QoS) configuration parameters.  Differentiated
   Services (DiffServ) module is an augmentation of the base QoS model.
   Remote Procedure Calls (RPC) or notification definition is not part
   of this document.  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 and action
   parameters to define the DiffServ module.  Queues and schedulers are
   stitched as part of diffserv policy itself or separate modules are
