1. A data transmission system having a data sending unit, a data receiving unit and a data transmission medium for data transmission from the data sending unit to the data receiving unit, comprising:

  • means for generating feature information of data transmission from the data sending unit to the data receiving unit in advance of execution of the data transmission;

    means for storing change of states of use of a bandwidth by data transmission now under execution;

    means for predicting a time of completion of the data transmission now under execution based on the change of states of use of the bandwidth and the feature information of the data transmission now under execution;

    means for determining a transmission rate for data transmission to be next executed at the time of completion of the data transmission now under execution based on the change of states of use of the bandwidth and the feature information of the data transmission to be next executed; and

    means for executing the data transmission to be next executed from the data sending unit according to the transmission rate at the time of completion of the data transmission now under execution.
