Host A and B are communicating over a TCP connection, and Host B has already received from A all bytes up through byte 100. Suppose Host A then sends two segments to Host B back-to-back. The first and second segments contain 200 and 300 bytes of data, respectively. In the first segment, the sequence number is 101, the source port number is 201, and the destination port number is 301. Host B sends an acknowledgment whenever it receives a segment from Host A. A. (3 points) In the second segment sent from Host A to B, what are the sequence number, source port number, and destination port number? B. (2 points) If the second segment arrives before the first segment, in the acknowledgment of the first arriving segment, what is the acknowledgment number?
