WebTCP in Action: slow start, congestion avoidance, and fast retransmit. Consider the figure below, which plots the evolution of TCP's congestion window at the beginning of each time unit (where the unit of time is equal to the RTT); see Figure 3.53 in the text. ... The times where TCP is in fast recovery are: 4. The times where TCP has a loss by ... WebJun 13, 2024 · TCP fast recovery algorithm is described as follows(from TCP illustrated vol. 1).
