Abstract
A mechanism is disclosed for identifying, classifying, and controlling flows in a network. In one implementation, a separate set of behavioral statistics is maintained for each flow. These behavioral statistics are updated as packets belonging to a flow are processed. Whenever a packet belonging to a flow is processed, a set of policies that the flow's behavioral statistics satisfy is determined. For each policy that the flow's behavioral statistics satisfy, actions that are associated with that policy are applied relative to the packet. The actions may be designed to cause a router to handle, in a user-specified manner, packets that are likely to represent a particular kind of traffic. Thus, different flows, such as VOIP, gaming, streaming, and P2P flows, which are associated with different behavioral statistics, may be handled in ways applicable for the specific application traffic type.
