1.  Introduction

   This document defines a base YANG [RFC6020] data module for Quality
   of Service (QoS) operational parameters.  Remote Procedure Calls
   (RPC) or notification definition is currently not part of this
   document and will be added later if necessary.  QoS configuration
   modules are defined by [I-D.asechoud-rtgwg-qos-model].

   This document doesn't include operational parameters for random-
   detect (RED), which is left to individual vendor to augment it.

2.  Terminology

   The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
   "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
   document are to be interpreted as described in [RFC2119].

3.  QoS Operational Model Design

   QoS operational model include QoS policy applied to an interface in
   each direction of traffic.  For each QoS policy applied to an
   interface the model further includes counters for associated
   Classifiers, Meters and Queues in a particular direction.  To
   modularize and for reusability, grouping have been defined for
   various counters of Classfier, Meters and Queues.  The target is
   assumed to be interface but the groupings can be used for any other
   target type where QoS policy is applied.

   [I-D.asechoud-rtgwg-qos-model] defines various building blocks for
   applying a QoS Policy on a target.  It includes QoS Policy
   configuration, which is a container of various classifiers and
   corresponding actions which are configured for traffic conditioning.
   This drafts defines the various counters for these building blocks.

   Classifier statistics contains counters for packets and bytes matched
   to the traffic in a direction and also average rate at which traffic
   is hitting a classifier.  Classification criterion may be based on
   IP, MPLS or Ethernet.  Counters defined in this draft are agnostic to
   underlying dataplane technology.

   Statistics of meter is modeled based on commonly used alogrithms in
