Question

(a) In the second segment sent from Host A to B, what are the sequence number, source port number, and destination port number?

(b) If the first segment arrives before the second segment, in the acknowledgment of the first arriving segments, what is the ACK number, the source port number. and the destination port number?

In Figure 2, Hosts A and B are communicating over a Transmission Control Protocol (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.
