An RTO occurs when the sender is missing too many acknowledgments and decides to take a time out and stop sending altogether.

So What Are Retransmission Timeouts?Ī retransmission timeout (RTO), on the other hand, is quite a different beast. This actually happens all the time, and typically doesn't cause much of a problem: as the retransmission timer counts down, the packets are resent, and the network continues to hum along. When an outbound segment is handed down to an IP and there's no acknowledgment for the data before TCP's automatic timer expires, the segment is retransmitted.

TCP ( the Transmission Control Protocol) connects network devices to the internet.
