Timeout retransmission is an important mechanism for TCP to ensure data reliability. Its principle is to enable a timer after a data is sent,If no ACK packet is sent within a certain period of time, the data will be re-sent until the message is sent successfully. This is dataA repair mechanism is provided when the package is lost. Generally, retransmission occurs after timeout, but if the sender receives more than threeThe duplicate ack should realize that the data is lost and needs to be re-tra
