TCP sequence numbers are used by Transmission Control Protocol (TCP) to number each byte of data in a data stream. They are used to track the data packets that are sent over the network and to ensure that they are correctly received by the other end. The sequence number is increased by one for each byte that is transmitted, allowing the receiver to determine if any of the packets were lost or corrupted.
The TCP Sequence Number is a number that the Transmission Control Protocol (TCP) uses to determine which messages have been sent and received. It is a 32–bit value assigned to each byte of data sent over a network connection. This number helps to ensure that data does not become out of sequence during delivery, as a result of lost or corrupted packets. The TCP Sequence Number also works in conjunction with the Acknowledgement number to ensure that data that fails to arrive is retransmitted until the receipt of the data is confirmed.
