Via real time online bandwidth measurement, this method confirms the threshold value ssthresh. When the congestion window (CW) is less than a half of the threshold, the rule of exponent gain is followed. Otherwise CW gains each time a value of a half of difference of the threshold and CW (ssthresh-cwnd) to approach gradually the threshold. Until the difference is less than the regulation factor phi (ssthresh / 2>= phi >=2). Then CW is set as the threshold value to enter the stage of avoiding congestion. This invention can reduce the happening of loss of several texts in a window at the slowly start stage, reduce the package loss rate and raise the net transferring ability.
