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.

This document, as well as QPIM, are information models.  That is, they
represent information independent of a binding to a specific type of
