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
vendor requirements. The DiffServ model is based on DiffServ
architecture, and various references have been made to available
