IPQoS Classes

A class is a group of network flows that share similar characteristics. For example, an ISP might define classes to represent the different service levels that are offered to customers. An ASP might define SLAs that give different levels of service to various applications. For an ASP's QoS policy, a class might include outgoing FTP traffic that is bound for a particular destination IP address. Outgoing traffic from a company's external web site might also be defined as a class.

Grouping traffic into classes is a major part of planning your QoS policy. When you create classes by using the ipqosconf utility, you are actually configuring the ipgpc classifier.
