1. Introduction
This document defines a base YANG [RFC6020] 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 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 and action parameters to define the
DiffServ module. It is left up to individual vendors to stitch some
of the 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
