Abstract: An attack stream identification method, apparatus, and device on a software defined network is presented, where an invalid stream filter table is stored in a switch, and the method includes the steps of the switch receives a data packet of a data stream and searches, according to a characteristic value of the data packet, the invalid stream filter table for a state field of a filter entry; when the state field is a suspected attack stream state or a non-attack stream state, the switch sends a report message to a controller, determines a rate value for sending the report message to the controller, and fills the rate value in a rate field of the filter entry; and when the rate value is greater than a preset rate threshold, the switch changes the state field of the filter entry to an attack stream state.

Abstract: A data packet forwarding solution, which relates to the field of network transmission. A virtual switch in the solution saves a flow entry as an aging flow entry deleted from a flow table in a switch, and receives a reporting data packet generated according to a forwarding data packet when the forwarding data packet fails to match each flow entry in the flow table in the switch and a secure channel between the switch and the controller is faulty, delivers an aging flow entry matching the reporting data packet from an aging flow table to the switch, where the aging flow table includes one or more flow entries that are deleted as aging flow entries from a flow table in the switch.
