Abstract: A system includes a server that comprises a virtualization layer in which a hardware resource is virtualized, and a virtualization control apparatus. The virtualization control apparatus requests first information regarding the hardware resource to the server, registers second information corresponding to the first information acquired from the server, and uses the second information to control a network function (Virtual Network Function: VNF) implemented and virtualized by software operating on a virtual machine implemented on the virtualization layer.

Abstract: A virtualization management/orchestration apparatus is provided with: a Network Function Virtualization Orchestrator (NFVO) that reads a Network Service Descriptor (NSD) in which an entry defining dependency between a VNF and a prescribed element is provided, and creates the VNF and the prescribed element according to the dependency defined in the NSD; and/or a VNF manager (VNFM) that reads a Virtualized Network Function Descriptor (VNFD) provided with an entry defining dependency between a VM and a prescribed element, and creates the VM and the prescribed element according to the dependency defined in the VNFD.
