Question 6Phases of TCP congestion control. Consider the figure below, which plots the evolution of TCP's congestionwindow at the beginning of each time unit (where the unit of time is equal to the RTT); see Figure 3.53 in thetext. In the abstract model for this problem, TCP sends a "flight" of packets of size cwnd at the beginning of eachtime unit. The result of sending that flight of packets is that either (i) all packets are ACKed at the end of the timeunit, (ii) there is a timeout for the first packet, or (iii) there is a triple duplicate ACK for the first packet.Congestion window size (in segments)403530252015105010 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39Time unit (in RTT)A.

Additive-Increase, Multiplicative Decrease (AIMD) refers to... a. TCP increases its round-trip time estimate by 1 second with each ACK received, and divides it by two with each loss event. O b. TCP's congestion control mechanism in the congestion-avoidance phase, in which the congestion window is increased by 1 maximum segment size (MSS) every round-trip time (RT), and decreased by 1/2 when there's a loss event indicated by 3 duplicate ACKS. c. TCP's ability to add additional receivers, one-by-one, until there are too many receivers. At this point, TCP reduces the number of receivers by 1/2 by sending those receivers a reset (RST) packet.
Consider that only a single TCP (Reno) connection uses one 10Mbps link which does not buffer any data. Suppose that this link is the only congested link between the sending and receiving hosts. Assume that the TCP sender has a huge file to send to the receiver, and the receiver's receive buffer is much larger than the congestion window. We also make the following assumptions: each TCP segment size is 1,500 bytes; the two-way propagation delay of this connection is 150 msec; and this TCP connection is always in congestion avoidance phase, that is, ignore slow start. A. What is the maximum window size (in segments) that this TCP connection can achieve? B. What is the average window size (in segments) and average throughput (in bps) Of this TCP connection? C. How long would it take for this TCP connection to reach its maximum window again after recovering from a packet loss?

Dear Writer are you sure about the solution?I have this olution can you pleaae double check it? For each recognized segment in TCP slow start, the congestion window grows by one MSS. The congestion control method initiates a timeout and resets the congestion window to 1 MSS when all sent packets are lost. Yet, the threshold is also set to half of the current congestion window since the connection is still in the sluggish start phase. In order to obtain the slow start threshold, we must first determine the congestion window at the beginning of cycle 8 and then divide it by 2. One segment is transmitted and acknowledged in Round 1, and the congestion window is one MSS. Two segments are transmitted and acknowledged in Round 2, which has a congestion window of two MSS. In Round 3, 4 MSS of the congestion window is transmitted and acknowledged together with 4 segments. In Round 4, every packet that was sent is lost, therefore the congestion window is once again set to 1 MSS. Two segments…
