You need to send a 2100-byte chunk of data using TCP from Computer A to Computer B. TCP segments arecarried in IP datagrams with a 20-byte header. IP datagrams are carried in a data link frame with a 10-byteheader. The maximum segment size for TCP is 800 bytes. The physical layer protocol can support a datarate of 1 Mbps. The round-trip time is10 ms between the sender and the receiver.Data must be sent over three links: (1) from Computer A to the first router, (2) from the first router to thesecond router, and (3) from the second router to Computer B. How long will it take to create a TCPconnection, deliver the data from Computer A to Computer B, and close the connection? Ignore any effectsof TCP congestion control or flow control. All links are lightly loaded so there are no queuing delays. Showyour work.

Consider transferring an enormous file of L bytes from Host A to Host B. Assume an MSS of 536 bytes.a. What is the maximum value of L such that TCP sequence numbers are not exhausted? Recall that the TCP sequence number field has 4 bytes.b. For the L you obtain in (a), find how long it takes to transmit the file. Assume that a total of 66 bytes of transport, network, and data-link header are added to each segment before the resulting packet is sent out over a 155 Mbps link. Ignore flow control and congestion control so A can pump out the segments back to back and continuously.
Host A and B are communicating over a TCP connection, and Host B has already received from A all bytes up through byte 126. Suppose Host A then sends two segments to Host B back-to-back. The first and second segments contain 80 and 40 bytes of data, respectively. In the first segment, the sequence number is 127, the source port number is 302, and the destination port number is 80. Host B sends an acknowledgment whenever it receives a segment from Host A. Suppose the two segments sent by A arrive in order at B. The first acknowledgment is lost and the second acknowledgment arrives after the first timeout interval. Draw a timing diagram, showing these segments and all other segments and acknowledgments sent. (Assume there is no additional packet loss.) For each segment in your figure, provide the sequence number and the number of bytes of data; for each acknowledgment that you add, provide the acknowledgment number.

Host A and B are linked directly to a 100 Mbps link. There is a TCP link between the two servers, and the host A sends a huge file to host B. Host A can transmit its application data to its TCP socket at a rate of 120 Mbps, but Host B can read its TCP buffer at a maximum speed of 50 Mbps. Describe the TCP flow control effect.
Host A and B are communicating over a TCP connection. Host B has already received from Host A all bytes up through byte 23. Suppose Host A then sends two segments to Host B back-to-back. The first and the second segments contain 30 and 50 bytes of data, respectively. In the first segment, the sequence number is 24, the source port number is 3000, and the destination port number is 80. Host B sends an acknowledgment whenever it receives a segment from Host A. A. In the second segment sent from Host A to B, what arethe sequence number_________,source port number __________,and destination port number__________?B. If the second segment arrives after the first segment, in the acknowledgment of the second segment, what arethe acknowledgment number___________,the source port number__________,and the destination port number __________?C. If the second segment arrives before the first segment, in the acknowledgment of the first arriving segment,what is the acknowledgment number ___________?D.…
The filed “window size” in TCP header is in length of 16 bit. It allows 64KB as the maximal size for a TCP segment by default. Under some circumstances, the sending rate is pretty high and it results in a very short sending time (<2ms). But the end to end transmission delay is 50ms. Therefore the idle rate of a channel will be more than 2/3 . How does TCP solve this problem?
. Suppose Host A sends over a TCP connection to Host B one segment with sequence number 3777 and 1500 bytes of data. Assuming the segment is received correctly, what is the sequence number of the ACK that Host B sents to Host A for this segment? 2.Calculate the the Internet checksum of 0100 1011 1001 1111 and1100 1100 0101 1101. 3.How many control messages are required to close a TCP connection?
Consider the Host Aand Host B TCP link. Assume that the TCP segments that fly from host Ato host B have source port x and destination port y. What are the source and destination port numbers of Host B to Host A segments?
Given a TCP host whose MSS and CW values are both set to 1,460 bytes, what will the value of CW be after two packets are sent and successfully ACKed?
Host A is sending an enormous file to Host B over a TCP connection. Over this connection there is never any packet loss and the timers never expire. Denote the transmission rate of the link connecting Host A to the Internet by R bps. Suppose that the process in Host A is capable of sending data into its TCP socket at a rate S bps, where S=10·R. Further suppose that the TCP receive buffer is large enough to hold the entire file, and the send buffer can hold only one percent of the file. What would prevent the process in Host A from continuously passing data to its TCP socket at rate S bps? TCP flow control? TCP congestion control? Or something else? Elaborate.
Suppose two hosts are connected with each other by means of a 100-Mbps link, and assume the round-trip time between them is 1 ms. What is the minimum TCP window size that would let TCP achieve the maximum possible throughput between these two hosts? (Note: Assume no overhead.)
3.5-4 TCP sequence numbers and ACKs (2). Suppose that as shown in the figure below, a TCP sender is sending segments with 100 bytes of payload. The TCP sender sends five segments with sequence numbers 100, 200, 300, 400, and 500. Suppose that the segment with sequence number 300 is lost. The TCP receiver will buffer correctly-received but not-yet-in-order segments for later delivery to the application layer (once missing segments are later received).
