4. Consider following figure. TCP sender wants to send a total of 20 segments to the receiver and sends
an initial window of 5 segments at t = 1, 2, 3, 4, & 5, respectively. Suppose the initial value of the

between the sender and receiver is 7 time units, and so the first segment arrives at the receiver at t = 8,
and an ACK for this segment arrives at t = 15.

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.
Host A sends the information of size 3000 bytes to Host B using TCP protocol. As long as Host B receives each packet in size 1000 bytes, Host B must acknowledge Host A. We assume the header size in each packet is 40 bytes, the starting sequence number used by Host A is 1000, and the window size of the sender side is 3000 bytes. What is the value of SND.NXT when the first packet is sent out, but not acknowledged? 1000 2000 3000 1999 If a host is monitored, and there are seven TCP packets captured: {S1, S2, S3, S4, S5, S6, E1}, where Si represents ith Send packet, and Ej represent jth Echo packet. E1 here acknowledges and echoes all the six Send packets cumulatively. Which of the follow matching can make more sense to represent the RTT of the connection chain? E1 matches with S1 E1 matches with S4 E1 matches with S5 E1 matches with S6
Q1.Suppose a client, say C, has established a TCP connection with a server, say S. After establishing the connection, the sender sends two TCP messages with data back-to-back ( the first TCP message with sequence number 32 and the second TCP message with sequence number 100). a. What is the sequence number chosen by the client? What could be the reason for choosing this value of sequence number?b. What is the data size of first and second TCP data messages?c. Suppose the server receives the first and second TCP messages with data with the difference of 100 milliseconds delay. What could be the ACK number for both the TCP data messages from the server side as per the TCP RFC.
Find number of data in first segment for given scenario: In the given scenario, "Host A" sends two TCP segments to "Host B" over the TCP connection. • The sequence number of first segment is "90". • The sequence number of second segment is "110".
TCP is a sliding window protocol. This means. а. there can be more than one segment "in flight" (sent but no ACK has been received) at a time. O b. the TCP retransmission timer slides up as ACKS are received. O c. there can only be one segment outstanding (sent but no ACK has been received) at at time.
Consider a simple protocol for transferring files over a link. After some initial negotiation, A sends data packets of size 1 KB to B; B then replies with an acknowledgment. A always waits for each ACK before sending the next data packet; this is known as stop-and-wait. Packets that are overdue are presumed lost and are retransmitted. (a) In the absence of any packet losses or duplications, explain why it is not necessary to include any "sequence number" data in the packet headers. (b) Suppose that the link can lose occasional packets, but that packets that do arrive always arrive in the order sent. Is a 2-bit sequence number (that is, N mod 4) enough for A and B to detect and resend any lost packets? Is a 1-bit sequence number enough? (c) Now suppose that the link can deliver out of order and that sometimes a packet can be delivered as much as 1 minute after subsequent packets. How does this change the sequence number requirements?
If there is wide variation in the TCP segment size , it is natural to organize the buffers as a pool of fixed-sized buffers, with one segment per buffer TRUE OR FALSE
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.
DO NOT COPY FROM OTHER WEBSITES. THANK YOU! Assume that a TCP process A first measures the actual round trip time to another TCP process to be 20 ms, and A thus sets its estimated round trip time to be 20 ms. The next actual round trip time that A sees is 40 ms. In response A increases its estimated round trip to 60 ms. The next actual round trip time that A sees is 30 ms. What is the next estimated round trip computed by A? Justify your answer

Find out the generic format for TCP header options from Request for Comments 793. (a) Outline a strategy that would expand the space available for Options beyond the current limit of 44 bytes.

List several such receiver actions that might be useful, and try to give an example application of each.
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.
