Abstract: A method includes configuring an IP subnet at an operations support system in a telecommunications network, the operations support system configured for managing at least one virtual networking function; configuring the IP subnet for use by the at least one virtual networking function, the virtual networking function including at least one virtual machine; configuring the IP subnet for use by the least one virtual machine, the at least one virtual machine including a processor and a memory; sending, from the at least one virtual machine, IP subnet data to a virtual networking function manager having a processor and a memory; and sending, from the virtual networking function manager, the IP subnet data to a virtual infrastructure manager configured for managing internal and external connectivity of the IP subnet data.

Abstract: In examples, a mobile network apparatus, a computer program and a method is discussed, including at least one processor, and at least one memory storing program instructions that, when executed by the at least one processor, cause to: Receive a create request for requesting data connectivity. Based on the create request, perform a static load balancing. Based on the static load balancing, perform a caching relating to a dynamic load balancing and perform the dynamic load balancing. A load balancing method may be scalable with a grace period.
