If three ACKs are received, there is a weaker possibility of congestion; a segment may have been dropped, but some segments after that may have arrived safely since three ACKs are received. This is called fast transmission and fast recovery. In this case, TCP has a weaker reaction: a. five star fine photography

WebbIn this problem, we consider the delay introduced by the TCP slow-start phase. Consider a client and a Web server directly connected by one link of rate R. Suppose the client wants to retrieve an object whose size is exactly equal … WebbTCP reacts by- Setting the slow start threshold to half of the current congestion window size. Decreasing the congestion window size to 2 MSS (Given value is used). Resuming the slow start phase. So now, Slow start threshold = 10 MSS / 2 = 5 MSS Congestion window size = 2 MSS Slow Start Phase- Window size at the start of 6 th transmission = 2 MSS
