Features Description
QoS Overview
For network traffic, the Quality of Service (QoS) involves bandwidth, delay,
and packet loss rate during traffic forwarding process. This document
describes:
z Introduction to QoS
z Introduction to QoS Service Models
z QoS Techniques Overview
QoS Configuration
Approaches
Two approaches are available for you to configure QoS: policy-based and
non policy-based. This document describes:
z QoS Configuration Approach Overview
z Configuring a QoS Policy
Priority Mapping
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
This document describes:
z Traffic Policing, Traffic Shaping, and Line Rate Overview
z Configuring Traffic Policing
z Configuring GTS
z Configuring the Line Rate
Congestion
Management
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:
z Configuring SP Queuing
z Configure WRR Queuing
z Configuring WFQ Queuing
z Configuring SP+WRR Queues
Traffic Filtering
This document describes how to filter in or filter out a class of traffic by
associating the class with a traffic filtering action.
Priority Marking
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
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
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
Class-based accounting collects statistics on a per-traffic class basis. This
document describes how to configure class-based accounting.
User Profile
User profile provides a configuration template to save predefined
configurations. This document describes:
z Creating a User Profile
z Configuring a User Profile
z Enabling a User Profile
