Abrégé

A design apparatus optimizes, with a first granularity (for example, a real number solution), a traffic volume allocated to each of links between adjacent nodes included in a network. In addition, the design apparatus calculates an approximation solution obtained by approximating, with a second granularity (for example, an integer solution), the traffic volume having been optimized with the first granularity. Furthermore, the design apparatus maps logical paths to each of routes constituted by the links in accordance with the approximated traffic volume.

Abrégé

When a controller receives a tunnel setting order from a high-order Ops (operation system), the controller divides the setting order into a first setting processing step related to setting registration of a user, a second setting processing step related to a transfer surface of the tunnel, a third setting processing step related to an interface of each transfer apparatus used for a tunnel of the transfer surface, and a fourth setting processing step related to a parameter to be set to the interface and stores the setting processing steps in a setting management DB. Subsequently, the controller creates a configuration for executing each setting processing step indicated in the tunnel setting order by reflecting information indicated in each divided setting processing step to a template of each setting processing step. In addition, the controller inputs the created configuration to a transfer apparatus at a setting destination of the tunnel.

An object of the present invention is to provide a communication method, a transceiver, a relay, a communication system, and a program capable of performing high-speed communication even in a case where there is an obstacle between two separated points in water. An object of the present invention is to provide a communication method, a transceiver, a relay, a communication system, and a program capable of performing high-speed communication even in a case where there is an obstacle between two separated points in water. In this communication method, two points each confirm the other's position by using sound wave communication which is likely to be diffracted as a wave due to a relatively small frequency and a large wavelength. Since the communication method uses optical wireless communication in which straightness is high but high-speed communication is possible, a path for communication while avoiding an obstacle via a relay is calculated. In the communication method, the relay is guided and moved to an appropriate place according to the calculated path, and a signal is transmitted and received by using optical wireless communication using the relay that has moved to an appropriate place.

Abrégé

This image restoration device comprises a mask image generation unit, a pixel restoration unit, and an image synthesis unit. The mask image generation unit generates a mask image for an unnecessary object from the input image. The pixel restoration unit first performs down-sampling processing on the input image and the mask image to generate a downsized input image and a downsized mask image by reducing the number of pixels. Next, the pixel restoration unit uses the downsized input image and the downsized mask image to perform object removal processing and pixel restoration processing on a missing region in which the object is removed and generates a downsized restoration image. Then, the pixel restoration unit performs up-sampling processing on the downsized restoration image to generate a restoration image having the same size as that of the original input image. Next, the pixel restoration unit uses the mask image and the restoration image to perform pixel restoration processing on the missing region to generate a final restoration image. The image synthesis unit synthesizes an image by using the input image and the final restoration image.
