A storage unit stores statistical information including an amount of resource consumption and performance information, which represents a performance, of each piece of hardware of a plurality of types that are candidates for an arrangement destination of a function, an accepting unit accepts inputs of description details of a function in a high-level language corresponding to the hardware of the plurality of types, and a performance requirement that represents a required performance, a performance predicting unit calculates a predicted performance, and a predicted amount of resource consumption, using the description details and a predetermined algorithm for each piece of hardware; and a device selecting unit selects, as an arrangement destination, hardware with the calculated predicted performance and the performance information satisfying the performance requirement and a total value of the predicted amount of resource consumption and the amount of resource consumption being equal to or smaller than a resource capacity.

Installation device and installation method

A counter router () assigns predetermined information specifying a terminal () and a sequence number according to the predetermined information to a packet which is received and destined for the terminal (). Further, the counter router () transfers the packet to which the predetermined information and the sequence number are assigned, to a subscriber accommodation router () via a relay device. Further, the subscriber accommodation router () stores, in an aggregation server (), the predetermined information and the sequence number which are assigned to the packet transferred from the counter router ().

Information collecting system and information collecting method

A communication system includes a programmable switch configured to perform packet transfer and queuing, a plurality of VNFs configured to execute network functions on packets, and a controller configured to control the programmable switch including a queue distribution unit configured to distribute input packets to any of the plurality of VNFs according to an instruction of the controller with respect to a queue group, the plurality of VNFs each include a load measurement unit configured to measure an amount of consumption of server resources and notify the controller of a load status, and the controller includes a load analysis unit configured to analyze a load of each of the plurality of VNFs based on a certain rule, and a queue control unit configured to change a queue distribution rule.

Communication system and communication method

A communication system includes a flow collector that collects traffic of an NW edge accommodating CPE, an NFVO that provides an instruction to add or remove a resource of a VNF, a resource management device that notifies the NFVO of an increased or decreased resource amount and an addition or removal instruction of the VNF based on an increase or decrease of the traffic of the NW edge collected by the flow collector, and that decides on the VNF which becomes a redirection destination of the traffic of the NW edge in response to execution of addition or removal of the VNF by the NFVO, a VIM that adds or removes the VNF in accordance with an instruction from the NFVO, and a flow controller that instructs the NW edge to set the VNF decided by the resource management device as the redirection destination of the traffic.

A control systemmay include a packet size analysis unit () that analyzes a distribution of packet sizes of traffic input to VNFs, a capacity calculation unit () that calculates a traffic volume per unit time processible by one VNF based on VNF capacity information indicating a traffic volume (bps, pps) per unit time processible by one VNF for a packet size and the distribution of the packet sizes input to the VNFs, and an installation number calculation unit () that calculates the number of VNFs to be increased or decreased based on the traffic volume per unit time processible by one VNF and the resource amount necessary for forwarding of the traffic.

Control device and control method

A shooting instruction device selects one of preset shooting patterns according to the type and scale of the disaster to cope with, then inputs shooting conditions corresponding to the selected shooting pattern, and sends a shooting instruction . A video camera apparatus loaded on a helicopter makes a flight plan based on the received shooting instruction , then shoots the position of a shooting target, then adds a still picture mark to a video signal , and sends it together with associated data . An information display device extracts a still picture from a video signal with the still picture mark, and displays the still picture together with the associated data

Remote-controlled shooting system, video camera apparatus and remote-controlled shooting method
