  • Service scaling in communications
    Patent number: 10243863
    Abstract: A method is disclosed for downscaling a deep packet inspection service in a network apparatus. The method comprises receiving data flow in a gateway virtual machine via a software defined networking switch, and keeping track of data flow and control flow and their state per subscriber. If needed, a new deep packet inspection virtual machine is selected for the data flow. The software defined networking switch is informed on the selection of the new deep packet inspection virtual machine. The new deep packet inspection virtual machine is instructed to re-create a flow identification for the data flow to ensure deep packet inspection service continuity.

  • Service offloading in communications
    Patent number: 10057177
    Abstract: A method is disclosed for service offloading in a communications system, the method comprising determining, in a network apparatus, whether a traffic flow has been properly classified by a deep packet inspection virtual machine. If the traffic flow has been properly classified by the deep packet inspection virtual machine, the method comprises instructing a software defined networking controller to stop sending further packets of said traffic flow to the deep packet inspection virtual machine.
