1 QoSM overview
Developed based on the IMC Platform, the QoS Manager (QoSM) is a component that manages QoS
configurations of devices. QoS configurations mitigate bandwidth, delay, jitter, and packet loss issues in
the network.
QoSM provides differentiated treatment for traffic by classifying the traffic and taking actions on different
classes of traffic.
QoSM enables you to use network resources more effectively and provides guaranteed services for
network traffic.
Features and benefits
QoSM has the following features and benefits:
• Configuration detection and audit—QoSM can detect QoS capability sets that are supported by
devices. This can prevent administrators from deploying QoS configurations beyond devices' QoS
capabilities. If the administrator deploys QoS configurations beyond devices' QoS capabilities,
QoSM filters unsupported QoS configurations. QoSM can also obtain the QoS configurations on
devices and detect QoS configuration changes by comparing the them with the set baseline QoS
configurations.
• Quick deployment—Quickly deploys common services and self-defined services to device
interfaces or VLANs. Common services include voice, video, SOM, and network protocol services.
• Simplified configuration—Deploys QoS configurations by performing Select Device
Interface/VLAN > Select Policy > Generate Task operations on a graphical interface.
• Configuration reusing—Any traffic classes can be associated with any traffic behaviors to form
policies, independently of devices. A policy can be applied to different devices.
Functions
QoSM provides the following functions:
• Quick Start—Provides information about basic concepts and functions in QoSM.
• QoS Device—Provides the following functions:
{
View the QoS features supported by devices.
{
View the QoS features that are already configured on devices.
{
Set the baseline to monitor QoS configuration changes.
• QoS Resource—QoS resources include traffic classes, traffic behaviors, and flow policies.
{
Classifier—Classifies packets based on the packet characteristics, such as IP addresses, MAC
addresses, and port numbers. Traffic classes provide the basis for differentiated treatment of
traffic.
{
Behavior—Defines actions to take on classified traffic, such as traffic policing, traffic shaping,
rate limiting, and congestion management.
