Question

g Consider a TCP connection between Host A and Host B. Suppose that the TCP segments traveling from Host A to Host B have source port number x and destination port number y. What are the source and destination port numbers for the segments traveling from Host B to Host A

Answer 1

Answer:

Source port number and destination port numbers for segment travelling from HOST B to HOST A are : Source port number is y , and Destination port number is x.

Explanation:
