Question

Suppose the two segments sent by A arrive in order at B. The first acknowledgment is lost, and the second acknowledgment arrives after the first time-out interval. Draw a timing diagram, showing these segments and all other segments and acknowledgments sent. (Assume there is no additional packet loss). For each segment in your figure, provide the sequence number and the number of bytes of data; for each acknowledgment that you add, provide the acknowledgment 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.
