control of the hijacked TCP connection. Internetworking with TCP/IP:Principles, Protocols, and Architecture. When the receiving host's buffer fills, the next acknowledgment contains a 0 in the window size, to stop transfer and allow the data in the buffer to be processed. It is newer and considerably more complex than TCP, and has not yet seen widespread deployment. The behavior of this timer is specified in RFC 6298. 47 A number of alternative congestion control algorithms, such as Vegas, Westwood, Veno, and Santa Cruz, have been proposed to help solve the wireless problem. Among this list is RFC 2581, TCP Congestion Control, one of the most important TCP-related RFCs in recent years, describes updated algorithms that avoid undue congestion. The TCP packages the data from these buffers into segments and calls on the internet module.g. While computing the checksum, the checksum field itself is replaced with zeros. This srtt value is what is finally used as the round-trip time estimate. The TCP receiver sends a D-ACK to indicate that no packets were lost, and the TCP sender can then reinstate the higher transmission-rate.

Thus the sender may then have to resend all 10,000 bytes. Unlike in connection hijacking, the connection is never desynchronized and communication continues as normal after the malicious payload is accepted. "Improving datacenter performance and robustness with multipath TCP". Archived from the original on March 6, 2009. "Transmission Control Protocol (TCP) Parameters: TCP Option Kind Numbers". Retrieved October 24, 2015. However, this does not mean that the 16-bit TCP checksum is redundant: remarkably, introduction of errors in packets between CRC-protected hops is common, but the end-to-end 16-bit TCP checksum catches most of these simple errors. This means that the retransmit timer fires only when the sender has received no acknowledgement for a long time.
