Question

14. (10 Points) Suppose Proces A running on Host Process B running on Host Y vi running on Host Z is communicating with Process via a TCP connection. Let x, y, and z be the IP addresses o and Host Z, respectively. Assume the port number o the port number of Process B is 464 26145, and the port number of Process D is 80. a. What are the identifiers of the socket associated with Process B when it is the destination? (2 Points) b. What are the identifiers of the socket associated with Process D when it is the destination? (2 Points) c. In a segment transmitted from B to A, what are the source IP addres, destination IP address, source port number, and destination port number? (2 Points) (In this order only) d. In a segment transmitted from D to C, what are the source IP address, destination IP address, source port number, and destination port number? (2 Points) e. If now Process E running Process D, is it possible that the port number of Process E is the same as that of Process C on Host Z? (2 Points) Explain X is communicating with a a UDP connection, and Process C D running on Host Y O/ru f Process A is 19157, 28, the port number of Process C is on Host X also wants to communicate with
