The first segment has sequence number 70; the second has sequence number 130. How much data in terms of bytes is in the first segment? Suppose that the first segment is lost but the second segment arrives at B. In the acknowledgment that Host B sends to Host A, what will be the acknowledgment number? c. Suppose that TCP's current estimated values for the round trip time (estimatedRTT) and deviation in the RTT (DevRTT) are 250 msec and 14 msec, respectively. Suppose that the next two measured values of the RTT are 270 msec and 240 msec. Compute the values of the TCP TimeoutInterval after each of these two measured RTT values are obtained.

Assume a TCP sender sends four packets of size 1024 bytes, carrying bytes 0-4095. If the second packet is lost, what is the content of the Acknowledgement field sent in response to the third packet? (If you think that no acknowledgement is sent, for example because the third packet is out of order, then answer -1.)
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.…

Host B sends an acknowledgment whenever it receives a segment from Host A. d. 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.
Is this the right answer or the wrong answer? Assume that the most recent SampleRTT for a TCP connection is one second. The TimeoutInterval setting for the connection must now be set to a value that is greater than one second.
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.

In the acknowledgement that Host B sends to Host A, what will be the acknowledgement number?

Question 8 Suppose that a TCP sender is sending segments with 100 bytes of payload. It sends five segments with sequence numbers 100, 200, 300, 400, and 500. Suppose that the segment with sequence number 300 is lost. What are the ACK values that the receiver returns to the sender after each of the four received segments are received. After receiving segment 100, the receiver responds with an ACK with value: After receiving segment 200, the receiver responds with an ACK with value: After receiving segment 400, the receiver responds with an ACK with value: After receiving segment 500, the receiver responds with an ACK with value: After receiving the retransmitted segment, the receiver responds with an ACK with value:
Host A and B are communicating over a TCP connection, and Host B has already received all bytes up through byte 100 (including Byte 100) from A. Suppose Host A then sends two packets to Host B back-to-back. The first and second packets contain 40 and 80 bytes of data, respectively. Host B sends an acknowledgment whenever it receives a packet from Host A. a. What is the sequence number of the first packet sent from Host A to Host B? What is the sequence number of the second packet sent from Host A to Host B? b. If the second packet arrives before the first packet, in the acknowledgment of the first arriving packet, what is the acknowledgment number? .
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".
- Suppose a TCP message that contains 1024 bytes of data and 20 bytes of TCP header is passed to IP for delivery across two networks interconnected by a router (i.e., it travels from the source host to a router to the destination host). The first network has an MTU of 1024 bytes; the second has an MTU of 576 bytes. Each network's MTU gives the size of the largest IP datagram that can be carried in a link-layer frame. Give the sizes and offsets of the sequence of fragments delivered to the network layer at the destination host. Assume all IP headers are 20 bytes.
