  • Publication number: 20200089525
    Abstract: According to an embodiment, a switch device includes a memory and one or more hardware processors coupled to the memory. The one or more hardware processors are configured to function as a selection unit and a determination unit. The selection unit, based on task schedule information synchronized with transmission schedule information where transmission timing of first data is determined for each priority of the first data, selects a first task of executing transfer processing of the first data and calculates an end time of transfer processing executed by the selected first task. The determination unit, from the end time and a current time, determines whether transfer processing of the first data is executable. The first task selected by the selection unit, when the transfer processing is executable, executes the transfer processing of the first data based on the transmission schedule information.

  • Publication number: 20190297025
    Abstract: According to an embodiment, a transfer control device controls transfer of data stored in a communication device. The transfer control device includes a memory and one or more hardware processors electrically coupled to the memory and configured to function as a control unit, and a determining unit. The control unit performs control for transferring the data to a first transmission buffer. The determining unit determines, depending on a state of the communication device, data to be restricted from being transferred. When transfer is to be restricted, the control unit delays transfer of data to be restricted from being transferred.
