Note that, in the old TCP code, the closing behaviour is slightly different. Usually in simulation, the server side of a connection is simulated by a PacketSink application and the client side is initiating the connect and close operations. In the old code, upon the client invoked Socket::Close(), a FIN packet is sent to the server and the server just respond with an ACK. In the new code, besides the ACK-to-FIN response, there will be another FIN packet sent in case the server side confirmed that it has nothing else to send. This is the case for PacketSink, as it called Socket::ShutdownSend() at the beginning. In the old code, the TCP state machine at client side will move from SYN_SENT to ESTABLISHED to FIN_WAIT_1 and FIN_WAIT_2 but never TIME_WAIT as it does not receive a FIN from the server side. We extended this to make the state machine transition complete. The last two line in the output above shows that ''two'' TCP sockets are closed. The first CLOSED state refers to the socket that handles the connected flow. The second one refers to the socket that is listening on port 50000 to wait for a new connection.</div></td><td class='diff-marker'> </td><td style="background-color: #f9f9f9; color: #333333; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #e6e6e6; vertical-align: top; white-space: pre-wrap;"><div>From the above, with the lines marked TcpSocketBase, one can verify the TCP state machine worked correctly.

And upon the finish of fast recovery phase (i.e. when partial or full ACK is received), window deflating can be observed. In cases that does not incur RTO, the time it takes to finish the transfer is around 0.5s shorter than the Tahoe counter part in the above experiments. However, when there is RTO, it takes a longer time than Tahoe.</ins></div></td></tr>
