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: The present invention addresses the problem of providing a gateway and a communication control method which make it possible to manage both a quasi-associated network and an associated network appropriately. A gateway and a communication control method of the present disclosure: interconnect a Public Switched Telephone Network (PSTN) and an Internet Protocol (IP) network; receive, via a certain link set, a signal including information indicating a transmission-source signal station; and determine the type of the network from which the signal has been transmitted, on the basis of a determination as to whether a signal station which is adjacent via the link set used for communicating the received signal corresponds to the transmission-source signal station indicated by the information included in the received signal.

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 virtual network function management apparatus includes: a virtual machine monitoring unit that detects a fault(s) in a virtual machine(s) operating on a virtualized infrastructure management unit that manages a virtualized infrastructure; and a control unit that instructs the virtualized infrastructure management unit to recreate a virtual machine(s) in which a fault(s) has occurred after an image file(s) of the virtual machine(s) in which the fault(s) has occurred is logically updated so that the image file(s) of the virtual machine(s) in which the fault(s) has occurred can be backed up.
