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
