    摘要: A data transfer method includes: executing a process that stores sensor information including duplicate degrees and position information, the duplicate degrees indicating an amount of computers as transmission sources of inhibit signals received by the first computer; executing a process that transmits the inhibit signal including the duplicate degree in the sensor information to a computer that is present in a position to which direct communication via the short-distance radio communication is possible; executing a process that stores the duplicate degree in the inhibit signal, associates the duplicate degree with the transmission source of the inhibit signal, and increases the duplicate degree in the sensor information; and executing a process that transmits the position information in the sensor information to the management device in a case where the duplicate degree in the sensor information is higher than the duplicate degree associated with the transmission source of the inhibit signal.

    摘要: A method of causing a computer to execute: classifying, based on topology for indicating connection relationships among a data-provision apparatus, distribution-destination apparatuses corresponding to distribution destinations of distribution targets, and relay apparatuses configured to relay communications between the data-provision apparatus and the distribution-destination apparatuses, the mutual distribution-destination apparatuses; identifying a first distribution-destination apparatus having a highest communication speed of a directly connected link among the distribution-destination apparatuses belonging to the group; and creating a distribution schedule of the data in a manner that the data is transmitted from the data-provision apparatus to the first distribution-destination apparatus in the same group, and next, the data is transmitted from the first distribution-destination apparatus to a second distribution-destination apparatus other than the first distribution-destination apparatus in the group.

    摘要: A method for acquiring a packet of a monitoring target, the method includes, forming, by a control unit, a mirror path for arriving a mirror packet, of which a origin or a destination of a transmission is a virtual machine for the monitoring target, at a monitoring device which monitors the mirror packet through one or more relay devices, detecting, by the control unit, an occupation when a packet except the packet, of which the origin or the destination of a transmission is the virtual machine for the monitoring target, does not pass based on history information of the packet which passes the relay device, accumulating, by the monitoring device, the mirror packet which passes the relay device, and extracting, by the monitoring device, the mirror packet which arrived at in the occupation as the packet for the monitoring target.
