COMMUNICATION CONTROL DEVICE, INFORMATION PROCESSING DEVICE, COMMUNICATION CONTROL METHOD, AND INFORMATION PROCESSING METHOD

According to one embodiment, a communication control device includes a transmission control unit and a communication unit. The transmission control unit is configured to control transfer start timing of a first message stored in a queue, based on gate control information. The communication unit is configured to transmit the first message transferred from the transmission control unit in accordance with the transfer start timing. The transfer start timing of the first message is determined based on a transmission cost at a time when a second message, which has been already determined to pass through the gate, is transmitted by the communication unit, and a transfer status of the second message between the transmission control unit and the communication unit.
