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.

Virtual network function management for creating sequence using dependency entry defined to confirm constrain violation

Provided a management apparatus including a maintenance mode setting unit that transitions a first virtualization infrastructure (NFVI0) to a maintenance mode, a mobility control unit that at least instructs a virtualization deployment unit (VDU) on the first virtualization infrastructure in the maintenance mode to move to a second virtualization infrastructure (NFVI1), and a maintenance mode release unit that releases the maintenance mode of the first virtualization infrastructure (NFVI0).

Management of network functions virtualization and orchestration apparatus, system, management method, and program

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.

System, virtualization control apparatus, method for controlling a virtualization control apparatus, and program

A magnetic bubble element which is useful as an image information processing element. A thin film made of a magnetic bubble forming material has a plurality of wedge-formed patterns made of a non-magnetostriction soft magnetic thin film is formed on the upper surface of the thin film 16. A conductor grating comprising two undulating conductor patterns are provided each cycle of the undulation in both conductor patterns defining a wider pitch and a narrower pitch, each of the wedge-formed patterns being disposed over the corresponding part of one of the two conductor patterns defining the narrower pitch in a manner such that the apex portion and the bottom portion of each wedge shaped pattern extend into the parts forming the wider pitch.
