In our description of TCP in Figure 3.53. the value of the threshold. ssthresh, is set as ssthresh=cwnd/2 in several places and ssthresh value is referred to as being set to half the window size when a loss event occurred. Must the rate at which the sender is sending when the loss event occurred be approximately equal to cwnd segments per RTT? Explain your answer. If your answer is no. can you suggest a different manner in which sthresh should be set?
