During linear increase, TCP computes an increment to the congestion window as: Increment = MSS x (MSS/Congestion Window) Explain why computing this increment each time an ACK arrives may not result in the correct increment. Give a more precise definition for this increment. (Hint: A given ACK can acknowledge more or less than one MSS's worth of data.)

- Consider a client connecting to a web server via a router as shown in Fig.Q2. Client A sends a request to the server to retrieve a 7.5 Mbytes file. Given that the segment size is 50 Kbytes, the round trip time (RTT) between the server and client is 10 ms, the initial slow-start threshold is 16 and the client's buffer always has a storage space of 1 Mbytes. Assume that TCP Reno is used, there is no loss during transmission and the headers of protocols are ignored. 400 Mbps 200 Mbps 400 Mbps Link a Link b Link c Client Web Server Fig.Q2 (a) Describe how the value of sending window changes as a function of time (in units of RTT) during the whole connection time. 2.Assume that when establishing a TCP connection, the threshold for the Congestion Window (cwnd) is 1& segments. The congestion control algorithm is TCP Reno. In the oth round, a time out occurs.The ACK packets are then received correctly until the 1 Pth round. In this round, a triple duplicate ack occurs. Then until the 1Sth round, the ack packets are received correctly. Show these steps by plotting (the vertical axis is the congestion window capacity (cwnd) and the horizontal axis is the round number). Also specify the threshold value change each time it occurs. Graph the chart in any software you want and upload the fileConsider a TCP connection with congestion window size 40 KB, maximum segment size is 2 KB, if time taken by TCP connection to get 37 KB congestion window is 351 ms, round trip time of the connection is __(ms).
- In TCP Vegas, the calculation of Actual Rate is done by dividing the amount of data transmitted in one RTT interval by the length of the RTT. (a) Show that for any TCP, if the window size remains constant, then the amount of data transmitted in one RTT interval is constant once a full window-full is sent. Assume that the sender transmits each segment instantly upon receiving an ACK, packets are not lost and are delivered in order, segments are all the same size, and the first link along the path is not the slowest. (b) Give a timeline sketch showing that the amount of data per RIT above can be less than Congestion Window.Consider one TCP connection on a path with a bottleneck link with capacity L. We have a file of size F(assume F is a very large file size). If TCP segment size is B bytes, the two-way propagation delay is tp and connection is always in congestion avoidance phase, find the following: A. Maximum window size that TCP can achieve B. Average window size and average throughput in this TCP connection C. Time it will take from connection establishment to reaching the maximum window size.TCP congestion control example. Consider the figure below, where a TCP sender sends 8 TCP segments at t = 1, 2, 3, 4, 5, 6, 7, 8. Suppose the initial value of the sequence number is 0 and every segment sent to the receiver each contains 100 bytes. The delay between the sender and receiver is 5 time units, and so the first segment arrives at the receiver at t = 6. The ACKs sent by the receiver at t = 6, 7, 8, 10, 11, 12 are shown. The TCP segments (if any) sent by the sender at t = 11, 13, 15, 16, 17, 18 are not shown. The segment sent at t=4 is lost, as is the ACK segment sent at t=7. TCP sender t=1 T t=2 t=3 t=4+ t=5- t=6+ t=11 t=12 t=13 t=14 t=15 t=16 t=17 t=18 I data segment data segment data segment data segment data segment data segment data segment data segment ACK ACK ACK ACK ACK ACK Ty A A V V htt TCP receiver t=6 t=7 t=8 t=9 t=10 t=11 t=12 t=13 What does the sender do at t=17? You can assume for this question that no timeouts have occurred.

Suppose the initial value of the sequence number is 0 and every segment sent to the receiver each contains 100 bytes.

The segment sent at t=4 is lost, as is the ACK segment sent at t=7. t=1 T data segment t=2+ data segment data segment-- t=3 TCP sender TCP receiver t=4+ t=5+ data segment - data segment t=6+ t36 data segment t=7 data segment t=8 data segment t=9 ACK + t=10 k -- ACK t=11 t=11 t=12 t=12 t=13 t=13 t=14 ACK -ACK ACK t=15 t=16 t=17 ACK t=18 What does the sender do at t=17? You can assume for this question that no timeouts have occurred.Consider a client has established TCP connection with a server and sending data. The propagation delay is 5 ms and there are no timeouts and errors during transmission. The size of the receiver advertised window is 128 KB, the slow-start threshold at the client is 64 KB, and the maximum segment size is 4 KB. The connection is established at time T = 10 ms. What is the size of the congestion window (in KB) at time 90 ms after all acknowledgements are processed?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?
- 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.SEE MORE QUESTIONS
