For network traffic, the Quality of Service (QoS) involves bandwidth, delay,
and packet loss rate during traffic forwarding process. This document
describes:
Introduction to QoS
Introduction to QoS Service Models
QoS Techniques Overview
Two approaches are available for you to configure QoS: policy-based and
non policy-based. This document describes:
QoS Configuration Approach Overview
Configuring a QoS Policy
The priorities of a packet determine its transmission priority. There are two
types of priority: priorities carried in packets and priorities locally assigned
for scheduling only.
When a packet enters the device from a port, the device assigns a set of
QoS priority parameters to the packet based on a certain priority and
sometimes may modify its priority, according to certain rules depending on
device status. This process is called priority mapping.

Traffic Policing, Traffic Shaping, and Line Rate Overview
Configuring Traffic Policing
Configuring GTS
Configuring the Line Rate
The key to congestion management is how to define a dispatching policy
for resources to decide the order of forwarding packets when congestion
occurs. This document describes:
Configuring SP Queuing
Configure WRR Queuing
Configuring WFQ Queuing
Configuring SP+WRR Queues
This document describes how to filter in or filter out a class of traffic by
associating the class with a traffic filtering action.
This document describes how to marking the priority of the packets by
associating a class with a behavior configured with the priority marking
action
Traffic redirecting is the action of redirecting the packets matching the
specific match criteria to a certain location for processing. This document
describes how to configure traffic redirecting.
Traffic mirroring is the action of copying the specified packets to the
specified destination for packet analyzing and monitoring. This document
describes how to configure traffic mirroring.
Class-based accounting collects statistics on a per-traffic class basis. This
document describes how to configure class-based accounting.
User profile provides a configuration template to save predefined
configurations. This document describes:
