About QoS
A communications network plays a prominent role in the success of an organization. These
networks transport a multitude of applications and data including high quality video and real
time voice. Bandwidth-intensive applications stretch network capabilities and resources,
complement, add value and enhance every business process. Networks must provide secure,
predictable, measurable and guaranteed services.
Quality of Service can be achieved by managing delay, delay variation, bandwidth, and packet
loss parameters on a network. QoS provides successful end-to-end solutions by using a set of
techniques that manage the network resources.
The following sections discuss QoS techniques, and how to configure them.

Using Traffic Shaper

You can set bandwidth policies and control the flow of communication by using traffic shaper.
Traffic shaper is a bandwidth management solution that ensures the precedence of important
traffic over less important traffic. This allows you to continue your business with less disruption
even during network congestion. Traffic shaper uses stateful inspection technology to access and
analyze data derived from all communication layers. This data is used to classify traffic in eight
user-defined quality of service classes. Traffic shaper divides the available bandwidth among the
