The BIG-IP® system includes a feature known as traffic classes. A traffic class is a feature that you can use when implementing optimization profiles for modules such as the Application Acceleration Manager™.
A traffic class allows you to classify traffic according to a set of criteria that you define, such as source and destination IP addresses. In creating the traffic class, you define not only classification criteria, but also a classification ID. Once you have defined the traffic class and assigned the class to a virtual server, the system associates the classification ID to each traffic flow. In this way, the system can regulate the flow of traffic based on that classification.
When attempting to match traffic flows to a traffic class, the system uses the most specific match possible.
By creating a traffic class and assigning it to a virtual server, you can classify traffic according to a set of criteria that you specify.
