Scenarios: Quality of service policies

These quality of service (QoS) policy scenarios can help you understand the reasons and the methods to use QoS.

One of the best ways to learn about QoS is to see how the function works in your overall network picture. The following basic examples show why you need to use QoS policies and also provide some steps with instructions for creating the policies and classes of service.

The IP addresses and diagrams are fictitious and are only used for example purposes.

Scenario: Limiting browser traffic
You can use quality of service (QoS) to control traffic performance. Use a differentiated service policy to either limit or extend an application's performance within your network.
Scenario: Secure and predictable results (VPN and QoS)
If you are using a virtual private network (VPN), you can still create quality of service (QoS) policies.
Scenario: Limiting inbound connections
If you need to control the inbound connection requests that are made to your system, use an inbound admission policy.
Scenario: Predictable B2B traffic
If you need predictable delivery and still need to request a reservation, you also use an integrated service policy. This example uses a controlled load service.
Scenario: Dedicated delivery (IP telephony)
If you need dedicated delivery and want to request a reservation, you use an integrated service policy. There are two types of integrated service policies to create: guaranteed and controlled load. In this example, guaranteed service is used.
Scenario: Monitoring current network statistics
Within the wizards, you need to set the performance limits that are based on individual network requirements.
