Host A and B are communicating over a TCP connection, and Host B has received from A and acknowledged all bytes so far. Suppose Host A then sends two segments to Host B back-to-back. The first and second segments contain 800 and 400 bytes of data, respectively. In the first segment, the sequence number is 1200, the source port number is 2000, and the destination port number is 3000. Host B sends an acknowledgement whenever it receives a segment from Host A. [ Select) : In the second segment sent from Host A to B, what is the sequence number? [ Select ] : If the first segment arrives before the second segment, in the acknowledgement of this segment, what is the acknowledgement number, the source port number, and the destination port number?
