Problems Pl. Suppose Client A initiates a Telnet session with Server S. At about the same time, Client B also initiates a Telnet session with Server S. Provide possible source and destiņation port numbers for a. The segments sent from A to S. b. The segments sent from B to S. c. The segments sent from S to A. d. The segments sent from S to B. e. If A and B are different hosts, is it possible that the source port number in the segments from A to S is the sarme as that from B to S? f. How about if they are the same host?

If A and B are different hosts, is it possible that the source port number in the segments from A to S is the same as that from B to S? f. How about if they are the same host P2. Consider Figure 3.5. What are the source and destination port values in the segments flowing from the server back to the clients" the IP addresses in the network-layer datagrams carrying the transport-layer segments? P3. UDP and TCP use Is complement for their checksums Suppose you have the following three 8-bit bytes: 01010011,01100110.01110100. What is the Is complement of the sum of these 8 bit bytes (Note that although UDP and TCP use 16-bit words in computing the checksum. for this problem you are being asked to consider 8-bit sams.1 Show all work. Why is it that UDP takes the Is complement of the sum, that is, why not just use the sum? With the Is processes? What are as 6:21 PM 42 F 12/9/2021
