title: Slow Start Threshold in TCP Reno
body: <p>Lets say, the timeout occured at the end of the slow start phase. At that time, the window size will be reduced to half. After that, it goes into congestion avoidance phase instead of going to slow start phase again. In this case, what is the slow start threshold? Is it the end of the slow start or the beginning of the congestion avoidance phase?</p>
