Abstract:
1. A data transfer device comprising: a data acquirer acquiring data from another device and storing the data in a buffer; a communicator transmitting the data stored in the buffer to a server connected to the data transfer device via a predetermined network; a line state acquirer acquiring line state data relating to a state of a line; a line state storer accumulating and storing the line state data acquired by the line state acquirer; a transmission data amount determiner determining an amount of transmittable data as the amount of data transmittable by one connection with the server, based on the line state data stored in the line state storer; and a transmission schedule generator generating a transmission schedule for data transmission to the server based on a total amount of data stored in the buffer and the amount of transmittable data, wherein the communicator transmits the data stored in the buffer according to the transmission schedule, when the total amount of the data stored in the buffer is larger than the amount of transmittable data, the transmission schedule generator includes information for enabling the communicator to transmit the data stored in the buffer by dividing the data according to a plurality of connections, in the transmission schedule, and the transmission schedule generator determines a time interval when transmitting by dividing the data according to the plurality of connections based on (i) a value obtained by dividing the total amount of the data stored in the buffer by the amount of transmittable data, and (ii) an allowed transmission time that is determined based on a current time and a time when the data acquirer acquires data next.
