  • Publication number: 20140156994
    Abstract: An information processing apparatus includes a storage unit and a processor. The storage unit stores a private key corresponding to a public key stored in a storage apparatus connected to the information processing apparatus through a network. The processor receives first data from the network. The processor decrypts second data included in the first data using the private key. The processor determines whether a result of the decryption is third data. The processor activates the information processing apparatus when the result of the decryption is the third data.

  • Publication number: 20130227566
    Abstract: According to a data collection method, an allocation determination unit detects one or more pairs of virtual machines communicating with each other from virtual machines on the basis of communication data exchanged between the virtual machines. The allocation determination unit selects one of information processing apparatuses, and determines how to reallocate the virtual machines in order that, out of the detected pairs, at least one of paired virtual machines running on a non-selected information processing apparatus runs on the selected information processing apparatus. A control unit reallocates the virtual machines in accordance with the determined reallocation, and controls the selected information processing apparatus so as to collect communication data relayed by the relay unit running on the selected information processing apparatus.

  • Publication number: 20130223248
    Abstract: When measuring a one-way packet transfer delay between first and second measurement devices in a time-asynchronous manner, the first measurement device transmits first packets each containing a first counter value at a time of transmission; and then transmits a second packet containing a second counter value at the time of the transmission. The second measurement device stores the first counter value extracted from each of the first packets, a third counter value at a time of reception, and reception time stamp information; calculates an incremental ratio between the first counter value and the third counter value per unit time; and calculates an expected fourth counter value at the time of the reception based on the second counter value and the incremental ratio, and obtains the transfer delay based on the calculated expected fourth counter value and an actual fourth counter value at the time of the reception.

  • Publication number: 20130223322
    Abstract: Each of two or more base stations notifies a communication controller of information on a first frequency band that the base station uses for radio communication. Based on the information on the first frequency bands acquired from the two or more base stations, the communication controller selects a second frequency band to be used by the two or more base stations to transmit the data with common content, and notifies the two or more base stations of information on the selected second frequency band. The two or more base stations transmit the data with common content based on the information on the second frequency band acquired from the communication controller.

  • Publication number: 20130226969
    Abstract: A data access control apparatus has a management information table in which identification information of a storage node specified as one to which transmission of a reference request is inhibited and a reference condition are associated with each other. When a reference condition and a reference request are received, a transmission processing unit transmits the received reference condition and a reference request to storage nodes except a storage node associated with the received reference condition in the management information table. A registration processing unit determines, based on a response from each storage node to which the reference request has been transmitted, a storage node in which no data matching the received reference condition is stored, and registers identification information of the determined storage node in the management information table in association with the received reference condition.
