Abstract: A method including obtaining a plurality of data sets each describing a specific virtualized network function, acquiring and processing control information related to at least one of a communication traffic situation in a communication network for which at least one virtualized network function is implementable and a resource usage situation in a virtualization infrastructure in which at least one virtualized network function can be instantiated, and adjusting an amount and type of at least one virtualized network function instantiated in the virtualization infrastructure for usage in the communication network by, based on the processed control information, selecting at least one virtualized network function from the obtained data sets, instantiating the selected at least one virtualized network function.

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.

Abstract: There is provided allocating cloud computing resources to process a user session by a gateway in a mobile communications network, and allocating the cloud computing resources in pairs to user sessions. Rules for the pair of allocated resources are determined such that incoming control plane traffic associated with the session is forwarded to the both cloud computing resources forming the pair.

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.
