Abstract: VNF (Virtual Network Function) descriptor (VNFD) is configured to include an entry that describes a definition of at least one predetermined apparatus connected to each VDU (Virtual Deployment Unit) on a same layer as an information element of the VDU, with a definition element including an apparatus name of the apparatus being provided under the entry and associated with the entry. The VNFD is received from a storage unit storing the VNFD, and an associated instance is created.

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.

Abstract: A virtualized network function management apparatus includes: an orchestration part; a virtualized network function management part; a storage part that holds priority hardware information in which a combination of physical resources, for an individual virtualized network function, as a deployment candidate of the virtualized network function is associated with information about a priority set to the combination of physical resources; and a virtualized infrastructure management part. The virtualized infrastructure management part reserves a combination of physical resources that satisfies resource and constraint information necessary for the virtualized network function in accordance with the priorities in the priority hardware information. Finally, the virtualized network function management apparatus creates a virtual machine by using the reserved combination of physical resources.

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 network functions virtualization management and orchestration system with a VNF descriptor (VNFD) including a information element that allows an instance created based on the VNFD to be distinguished by name. The information element includes an information element of a VM name that describes a naming rule for a virtual machine (VM).
