Why is the length of a TCP segment limited to 65,515 bytes? (Hint: Look at the definition of the Data Offset field of the TCP segment format.)
In a TCP data packet, if the sequence number has the value 001111, ACK number has the value 010110 and the urgent pointer has the value 001100 assuming that URG flag is set. What is the last urgent byte in the data section of the packet? All numbers are in binary.
. If size of a TCP segment is 1KB and header length value is 6, the sequence number = 3500. Given that URG flag = 1 and URG pointer = 45. Then what is the total size of data. How many of them are urgent, Give the sequence numbers of urgent data.
P27. 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. In the second segment sent from Host A to B, what are the sequence number, source port number, and destination port number? If the first segment arrives before the second segment, in the acknowledgment of the first arriving segment, what is the acknowledgment number, the source port number, and the destination port number? If the second segment arrives before the first segment, in the acknowledgment of the first arriving segment, what is the acknowledgment number? Suppose the two segments sent by A arrive in order at B.…

TCP is one of the most common protocols operating at the transport layer and providing reliable end to end devlivery. TCP header is a variable length header since it might contain OPTIONS field. Write a report explaining the different options that can be added in this field.
assume the data from application has been broken into datagram size of 420 bytes by TCP at sender and the sequence number of the first datagram is 1. What would be the acknowledgement number sending by the receiver after it receives 3rd datagram from the sender.
Compare the TCP header and the UDP header. List the fields in the TCP header that are not part of the UDP header. Give the reason for each missing field.
Is a TCP segment composed of a 20-byte header (excluding options) that is followed by any number of data bytes?
1. Suppose a TCP connection is transferring a file of 5550 bytes. The first byte is numbered 10001. What are the sequence numbers for each segment if each carries 500 bytes? How many Segments will be there ?
Suppose an extension of TCP allows window size much larger than 64 KB. Assume the extended TCP runs over a 100-Mbps link with RTT 100 ms, segment size is 1 KB, and receiving window size is 1 MB. How long does it take to send a 200 KB file?
In a TCP connection, the initial sequence number at the client site is 2171. The client opens the connection, sends three segments, the second of which carries 1000 bytes of data, and closes the connection. What is the value of the sequence number in each of the following segments sent by the client? a. The SYN segment b. The data segment c. The FIN segment
