Dynamically identifying and associating control packets to an application layer

摘要

A device may receive a control packet associated with a connection. The control packet may include a network address. The device may identify an application layer identifier that is associated with the network address. The device may identify a service rule associated with the application layer identifier. The service rule may identify a service to be applied to a data packet associated with the connection. The device may provide the control packet based on identifying the service rule. The control packet may be provided to permit the service to be applied to the data packet in accordance with the service rule.
