Consider the TCP trace in Figure 6.29. Identify time intervals representing slow start on startup, slow start after timeout, and linear-increase congestion avoidance. Explain what is going on from T = 0.5 to T = 1.9. The TCP version that generated this trace includes a feature absent from the TCP that generated Figure 6.11. What is this feature? This trace and the one in Figure 6.13 both lack a feature. What is it?
