Abstract: TCP was designed for wireline networks, where loss events are mostly caused by network congestion. The
congestion control mechanism of current TCP uses loss events as the indicator of congestion, and reduces
its congestion window size. However, when a lossy link is involved in a TCP connection, non-congestion
random losses should also be considered. The congestion window size should not be decreased if a loss event
is caused by link corruptions. To improve TCP performance over lossy links, in this paper, we first present that
