METHOD FOR ADJUSTING THE SIZE OF A CONGESTION WINDOW, AND TCP SYSTEM BASED ON SAME

摘要

The method for adjusting the size of a congestion window for TCP according to the present invention, comprises: a first step in which a TCP sender increases the congestion window size by a predetermined first rate in accordance with a slow start phase; a second step in which said TCP sender decreases said congestion window size by a predetermined second rate when a number of ACKs larger than a predetermined number of ACKs are received redundantly during the increase in said congestion window size performed in accordance with said slow start phase, and again increases said congestion window by the predetermined first size based on the ACK reception; and a step in which said TCP sender sets said congestion window size to a predetermined full congestion window size when the predetermined number of ACKs are redundantly received after said congestion window size has been decreased by the second rate.
