Solution
To determine whether or not there were retransmitted segments, you can follow these steps:
-
Check the sequence numbers for segments sent from the client to the server (in this case, gaia.cs.umass.edu). If all the sequence numbers are increasing and there are no repeats, it means there are no retransmitted segments. Retransmitted segments would have the same sequence number as the original segment that needed to be retransmitted.
-
Look for negative acknowledgments (NAKs) in the trace. NAKs are sent by the receiver when it detects a missing segment or error in the received data. If there are no NAKs, it suggests that all segments were received correctly and there were no retransmissions.
-
Check for timeouts in the trace. Timeouts occur when the sender does not receive an acknowledgment for a sent segment within a certain time period. This usually triggers the sender to retransmit the segment. If there are no timeouts, it indicates that acknowledgments were received in a timely manner for all sent segments, suggesting there were no retransmissions.

TCP sequence numbers and ACKs (2). Suppose that as shown in the figure below, a TCP sender is sending segments with 100 bytes of payload. The TCP sender sends five segments with sequence numbers 100, 200, 300, 400, and 500. Suppose that the segment with sequence number 300 is lost. The TCP receiver will buffer correctly-received but not-yet-in-order segments for later delivery to the application layer (once missing segments are later received). Complete the sentences below ....After receiving segment 100, the receiver responds with an ACK with value: After receiving segment 200, the receiver responds with an ACK with value: After receiving segment 500, the receiver responds with an ACK with value: After receiving the retransmitted segment 300, the receiver responds with an ACK with value:
