Abstract
The purpose of this document is to define an information model to
describe the quality of service (QoS) mechanisms inherent in
different network devices, including hosts. Broadly speaking, these
mechanisms describe the properties common to selecting and
conditioning traffic through the forwarding path (datapath) of a
network device. This selection and conditioning of traffic in the
datapath spans both major QoS architectures: Differentiated Services
and Integrated Services.
This document should be used with the QoS Policy Information Model
(QPIM) to model how policies can be defined to manage and configure
the QoS mechanisms (i.e., the classification, marking, metering,
dropping, queuing, and scheduling functionality) of devices.
Together, these two documents describe how to write QoS policy rules
to configure and manage the QoS mechanisms present in the datapaths
of devices.
