Question: This is a 6 mark question Suppose Host A sends two segments to Host B back-to-back over a TCP connection. The 1st and 2nd segments

This is a 6 mark question Suppose Host A sends two segments to Host B back-to-back over a TCP connection. The 1st and 2nd segments contain 75 and 40 bytes of data, respectively. In the first segment, the sequence number is 125, the source port number is 400, and the destination port number is 80. Host B sends an acknowledgment whenever it receives a segment from Host A.

a) What are the sequence number, source port number, and destination port number in the 2 nd segment sent from Host A to B?

b) If the 1 st segment arrives before the 2 nd segment, what is the acknowledgment number, the source port number, and the destination port number in the acknowledgment of the 1 st arriving segment?
