2019-09-10 00:45:26 +0000 | marked best answer | Is it possible to re-transmit only the last packet at TCP flow? I try to understand the TCP behavior, especially re-transmission. I did a small experiment and find the curious thing. The only last packet is re-transmitted. Why do this happen? I think if the last packet is time-out, then the other packets have to be time-out because All packets in the flow have same RTT and RTO. At first, I think it is due to Could you give me a little help? Thank you for reading :) For example, [1] H1->H2 send a 1500 bytes packet [2] H1->H2 send a 1500 bytes packet [3] H1->H2 send a 1500 bytes packet ... [n] H1->H2 send a 800 bytes packet [the last packet] [n+1] H1->H2 re-send a 800 bytes packet [the last packet] [n+2] H2->H1 send an ACK. [the raw data from EDIT: * Attached captured files * https://www.dropbox.com/s/1mtgtv5xof6... https://www.dropbox.com/s/1mtgtv5xof6... Each files is the packet captured at each host.
