Abstract:
1. A data transmission device comprising: a network interface unit that carries out a process of transmitting and receiving data to and from a network, and that detects data which are being transmitted in said network and notifies an identifier assigned to said data being transmitted in said network and a transmission timing of said data being transmitted in said network; a transmission timing prediction unit that monitors, by using the transmission timing and the identifier notified from said network interface unit, a transmission time period of data to which a same identifier is assigned from among the data being transmitted in the network, and that predicts a next transmission timing of said data to which the same identifier is assigned; a recording unit that stores a table of a plurality of transmission data types, as targets to be monitored, according to an identifier of each transmission data type, said table further including a transmission time period for each transmission data type and the predicted next transmission timing for each transmission data type, said recording unit adding a table entry upon determination that said data being transmitted in said network and data in the data transmission device satisfy a predetermined criteria; and a transmission timing control unit that delays a transmission timing of said data in the data transmission device when the transmission timing of the data in the data transmission device is within a threshold time difference of a transmission timing predicted by said transmission timing prediction unit stored in said table, and that commands said network interface unit to transmit the data in the data transmission device when the transmission timing of the data in the data transmission device is not within a threshold time difference of said predicted transmission timing.
