  • Patent number: 10719556
    Abstract: When a control unit performs a first operation on a data group, the control unit registers operation information corresponding to the data group in transfer control information. When the control unit extracts the data group as a transfer target, the control unit temporarily stores the corresponding operation information as stored information and transfers the data group to a storage apparatus. When the control unit performs a second operation on the data group while the data group is being transferred, the control unit updates the operation information registered in the transfer control information. When the transfer of the data group is completed, the control unit compares the operation information registered in the transfer control information with the stored information. If these items of information do not match, the control unit retransfers the data group to the storage apparatus.

  • Patent number: 10291505
    Abstract: A computer obtains a first packet group transmitted wirelessly by a first wireless communication apparatus and a second packet group transmitted wirelessly by a second wireless communication apparatus. The computer then detects a first non-communication period, during which there are no packets transmitted by the first wireless communication apparatus for a prescribed time or longer, and also detects a second non-communication period, during which there are no packets transmitted by the second wireless communication apparatus for the prescribed time or longer. The computer then determines based on an overlap between the first and second non-communication periods whether the first and second wireless communication apparatuses are connected to the same wireless base station.
