ExplainP27. 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.…Consider a datagram network using 8-bit host addresses and the forwarding table below: Prefix Interface 1001 1 10010 2 001 3 0011 4 0100 5 00 6 11 7 1101 8 Others 9 Suppose the following 8-bit datagram arrived at the router: 11011001, 10010100, 00100010, 10110101, 11001010, which interface(s) will they be forwarded?
- 6. Consider a network with some hosts. The traffic from one host to the other is provided. The question is to find the total bytes that are moving in the network from one host to the other and also for all the routes. The total bytes that are transferred for the day is as below. peter ann 1250 peter mary 910 mark mary, 1250 peter mary 450 peter andy 2924 paul peter 1218 paul helen 199 The first name is the source host, the second is the destination host and the number is the bytes that are transferred.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 backto-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. 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.Consider a datagram network using 32-bit host addresses, i.e., IP addresses range from 0 to 255.
