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: An electronic data inspection system capable of appropriately inspecting electronic data is provided. A first determination unit determines whether electronic data is illegally posted or not. A second determination unit determines whether the electronic data determined to be illegally posted by the first determination unit is illegally posted or not, with higher accuracy than the first determination unit. If the first determination unit or the second determination unit determines that the electronic data is not illegally posted, a registration unit deliverably stores the electronic data in a storage means. According to the number of pieces of electronic data that are determined to be illegally posted by the first determination unit and are waiting for determination by the second determination unit, a control unit causes the first determination unit to sequentially perform determination processing of other pieces of posted electronic data prior to the determination processing of electronic data by the second determination unit.

Abstract: A network function virtualization management and orchestration apparatus includes a VIM(s) and an upper entity(ies) of the VIM(s). The VIM(s) performs resource management and control of an NFVI(s) that provides an execution infrastructure(s) for a VNF(s) implemented and virtualized by software that operates on a virtual machine(s). The upper entity(ies) collects resource information about the NFVI(s) from the VIM(s) and determines a virtual machine allocation destination(s) based on the collected resource information about the NFVI(s). The VIM(s) generates a virtual machine(s) at the determined virtual machine allocation destination(s).

Abstract: There is provided an apparatus comprising: a unit that receives, from a sender, a registration request of an execution condition of a lifecycle of a virtual function under a virtual environment and registers the execution condition of the lifecycle in a storage unit; a unit that secures in advance one or more resources necessary for execution of the lifecycle in the virtual function; a unit that determines whether or not the execution condition of the lifecycle registered in the storage unit is satisfied; a unit that instructs the execution of the lifecycle when the execution condition of the lifecycle is satisfied; and a unit that notifies the lifecycle execution result to the sender of the registration request of the execution condition of the lifecycle.
