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.
