WebDec 14, 2024 · initcwnd = 10 segments Packets 3 and 4 are dropped. Let’s see the working of TCP reno with the help of an example: Step 1: Initially, sender sends 10 packets into the network without waiting for any ACK. cwnd = 10, inflight = 10. We are assuming beforehand that packet 3 and 4 are lost, the sender does not know about that yet.

Once cwnd reached ssthresh, AIMD starts. AIMD increases cwnd by 1 per RTT, so if packet drop occurs at cwnd = 125 then cwnd=10 and ssthresh=62 and Slow Start Restarts. Note: Packet loss can be detected either by RTO algorithm or Fast Retransmit.
