1.  Introduction

   This document defines a YANG [RFC7950] data model to specify Quality-
   of-Service (QoS) configurations.  QoS configurations include policies
   and profiles that allow an administrator of a device to classify,
   mark, rate-limit, and perform other actions on incoming and outgoing
   packets.

1.1.  Tree Diagram

   A simplified graphical representation of the data model is presented
   in Section 2.

   The meaning of the symbols in these diagrams is as follows:

   o Brackets "[" and "]" enclose list keys.

   o Curly braces "{" and "}" contain names of optional features that
   make the corresponding node conditional.

   o Abbreviations before data node names: "rw" means configuration
   (read-write), and "ro" state data (read-only).

   o Symbols after data node names: "?" means an optional node and "*"
   denotes a "list" or "leaf-list".

   o Parentheses enclose choice and case nodes, and case nodes are also
   marked with a colon (":").

   o Ellipsis ("...") stands for contents of subtrees that are not
   shown.

2.  Design of the Data Model

   This data model intends to describe the processing that a device
   performs on incoming and outgoing packets.  These actions include,
   but are not limited to, classification of packets, mapping of
   packets, and rate limiting, scheduling and queuing of packets.

   This data model has one top level container, qos, which consists of
   several second level containers.  Each of these second level
   containers describes a particular category of traffic handling, such
