  • Patent number: 9985754
    Abstract: An information processing apparatus comprises a first circuitry and a second circuitry. The first circuitry first/second demand response requests from first/second communication devices. The second circuitry creates first request content information representing contents of the first demand response request, sends it to a time-stamping authority, and acquires first time certification information containing a time stamp that the time-stamping authority issues for the first demand response request. The second circuitry stores the first time certification information in a storage device to be associates with the first demand response request; and determine, when the second demand response request is received, whether the second demand response request is retransmission of the first demand response request.

  • Patent number: 9702578
    Abstract: An air conditioning control system allows a supply air switching controller to alternately switch outside air control and return air control at a preset switching interval. The supply air switching controller is connected to an air conditioner placed to correspond to each room inside as an air conditioning control subject. The outside air control takes outside air into a temperature/humidity adjustment coil of the air conditioner by opening a first damper provided in the air conditioner in order to adjust an intake volume of the outside air into the air conditioner and by closing a second damper provided in the air conditioner in order to adjust an intake volume of return air from the room inside. The return air control takes the return air from the room inside into the temperature/humidity adjustment coil of the air conditioner by closing the first damper and opening the second damper.

  • Patent number: 9436516
    Abstract: A virtual machines management apparatus includes a virtual machine controller, a history storage, and a planning module. The virtual machine controller is configured to migrate virtual machines between plural physical servers. The history storage is configured to store, for each set of first virtual machines that were migrated to a same migration destination physical server parallel in time among the virtual machines migrated, history information. The planning module is configured to determine as to whether it is possible to start migrating a planning target virtual machine to a candidate migration destination physical server at a candidate migration start time based on a residual resource amount of the candidate migration destination physical server, a resource consumption of the planning target virtual machine, a sum of resource consumptions of migration-scheduled virtual machines, and the history information.

  • Patent number: 9397916
    Abstract: According to one embodiment, a communication device includes a clock to measure time, communication circuitry and processing circuitry. The communication circuitry transmits a request signal to the other communication device in a certain cycle, and receives a response signal transmitted in response to the request signal, from the other communication device. The processing circuitry changes a transmission timing of the request signal; compares first round-trip delay time with second round-trip delay time; and if a result of comparison shows that the second round-trip delay time is shorter than the first round-trip delay time, adjusts the time measured by the clock using a transmission time point of the second request signal and the reception time point of the second request signal in the other communication device, and the transmission time point of the second response signal from the other communication device and a reception time point of the second response signal.

  • Publication number: 20160124765
    Abstract: A dynamic resource allocation apparatus according to an embodiment includes a usage amount calculator, a spike detector, an allocation amount calculator, and an allocation amount setter. The usage amount calculator calculates a fixed usage amount which is a resource usage amount actually used for each time slot as a division of a resource fluctuation period of a virtual machine. The spike detector detects a spike of the fixed usage amount. The allocation amount calculator calculates a resource allocation amount to be allocated to the i-th time slot based on the past fixed usage amount in the i-th time slot and a detection result of a past spike in a time slot included in a predetermined range before and after the i-th time slot. The allocation amount setter sets an allocation amount to a virtual machine monitor which controls a virtual machine.
