According to an embodiment, a transfer device includes one or more hardware processors configured to function as a control unit and a first transfer unit. The control unit is configured to, by referring to scheduling information indicating a schedule of a timing at which data transfer occurs, dynamically control a maximum data request size that transfer of the data from a first storage unit to a second storage unit can be requested without waiting for reception of read completion notification. The first transfer unit is configured to read the data from the first storage unit and transfer the data to the second storage unit in units of maximum data transfer size equal to or less than the maximum data request size.

One embodiment provides an information processing device which includes a clock unit, a file access unit and a setting unit. The clock unit is configured to count up an elapsed time from a prescribed reference time if an origin time has not been set, and to count up an elapsed time from the origin time if the origin time has been set. The file access unit is configured to access a file which has time information given by an external device or the information processing device. The file is stored in a storage device. The setting unit is configured to acquire the time information from the file via the file access unit, and to set the acquired time information into the clock unit as the origin time.

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.

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.

According to one embodiment, a communication apparatus communicates with a partner apparatus through a network. The communication apparatus comprises a protocol analyzing unit that analyzes a transmission frame or a reception frame, the transmission frame being generated by an external CPU and being transmitted to the partner apparatus, the reception frame being received from the partner apparatus. The communication apparatus comprises a connection information managing unit that allocates a storage area in which connection information is stored, in a predetermined storing apparatus that can be accessed by the CPU, when a connection establishment request is detected from the transmission frame or the reception frame as a result of the analysis by the protocol analyzing unit, the connection information being used while being shared with the CPU. The protocol analyzing unit notifies the CPU of information indicating the storage area allocated by the connection information managing unit.

According to an embodiment, a communication device includes a communication unit, a transfer unit, an error detection unit, and a transfer disablement control unit. The communication unit receives a frame. The transfer unit transfers the frame to a frame storage unit of a transfer destination. The error detection unit detects an error in the frame. The transfer disablement control unit disables transfer by the transfer unit when an error is detected by the error detection unit.
摘要:
A communication control device according to an embodiment includes one or more hardware processors. The one or more hardware processors are configured to: perform control of transmission of messages by opening and closing a gate based on transmission permission information, the transmission permission information being generated based on gate control information including a plurality of entries for determining whether to open a plurality of gates corresponding to a plurality of queues, the transmission permission information indicating a time permitted to transmit messages in a period corresponding to one or more continuous entries or indicating an amount of transmittable messages in the period; and transmit and receive messages in accordance with the control.
