DATA RECEPTION APPARATUS, METHOD FOR CONTROLLING DATA RECEPTION APPARATUS, AND DATA TRANSMISSION AND RECEPTION SYSTEM INCLUDING DATA TRANSMISSION APPARATUS AND DATA RECEPTION APPARATUS

摘要

A data reception apparatus including a reception unit, a calculation unit, a determination unit and a notification unit. The reception unit receives a transmission announcement announcing transmission of data from a data transmission apparatus that transmits data. The calculation unit calculates a predicted use amount of a reception buffer that stores reception data on the basis of a current use amount of the reception buffer and an advance reservation amount indicating an amount of unreceived data among the data of which the transmission announcement is received that when the transmission announcement is received by the reception unit. The determination unit determines whether the predicted use amount calculated by the calculation unit exceeds a predetermined threshold. The notification unit notifies the data transmission apparatus of a stop of data transmission when the determination unit determines that the predicted use amount exceeds the predetermined threshold.

1. A data reception apparatus comprising:
a reception unit that receives a transmission announcement announcing transmission of data from a data transmission apparatus that transmits data; a calculation unit that, when the transmission announcement is received by the reception unit, calculates a predicted use amount of a reception buffer that stores reception data, on the basis of a current use amount of the reception buffer and an advance reservation amount indicating an amount of unreceived data among the data of which the transmission announcement is received; a determination unit that determines whether the predicted use amount calculated by the calculation unit exceeds a predetermined threshold; and a notification unit that, when the determination unit determines that the predicted use amount exceeds the predetermined threshold, notifies the data transmission apparatus of a stop of data transmission.
