Abstract
A system within a computer network identifies specific traffic flows originating from a given network entity and requests and applies appropriate policy rules or service treatments to the traffic flows. A network entity includes a flow declaration component that communicates with one or more application programs executing on the entity. The flow declaration component includes a message generator and an associated memory for storing one or more traffic flow data structures. For a given traffic flow, the application program issues one or more calls to the flow declaration component providing it with information identifying the traffic flows. The flow declaration component then opens a flow management session with a local policy enforcer that obtains policy rules or service treatments for the identified flow from a policy server and applies those rules or treatments to the specific traffic flows from the network entity.
