Abstract: According to an embodiment, an information processing apparatus includes one or more processors. The processors prefetch a scheduling entry corresponding a future time period in advance from scheduling information including one or more scheduling entries, each entry of which contains a transmission state and an interval for each of one or more transmission queues. The processors determine a starting time of transmission for one or more frames waiting for transmission in each queue, based on the scheduling entry. At least one of timing of the prefetching process and timing of the scheduling process is determined based on a result of comparison of a time difference and one or more thresholds. The time difference is a difference between current time and future time where the future time is a candidate for starting time of transmission.

Abstract: According to an embodiment, a processing apparatus includes a memory and a processor coupled to the memory. The processor is configured to: execute data access that is at least one of data writing to the memory and data reading from the memory; receive access control information for controlling timing of the data access to be executed; and control the timing of the data access based on the received access control information.

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.

Abstract: A transmission device includes a receiving unit and a transmission processing unit. The receiving unit receives transmission schedule information including a frame identifier (ID) of a frame to be transmitted and a transmission parameter relating to transmission timing of the frame. The transmission processing unit transmits a frame identified by the frame ID to a receiving device, according to the transmission parameter included in the transmission schedule information.

Abstract: According to an embodiment, an information processing apparatus includes a prefetch unit and a scheduler unit. The prefetch unit is configured to prefetch a scheduling entry corresponding a future time period in advance from scheduling information including one or more entries each of which at least contains a transmission state and interval for each of one or more transmission queues. The scheduler unit configured to determine a starting time of transmission for each frame waiting for transmission in each queue, on the basis of the prefetched entry.

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.
