  Transmission Control Protocol - Wikipedia, the free encyclopedia
The TCP checks that no bytes are damaged by using a checksum; one is computed at the sender for each block of data before it is sent, and checked at the receiver.
TCP window scale, as defined in RFC 1323, is an option used to increase the maximum window size from 65,535 bytes to 1 Gigabyte.
The TCP length field is the length of the TCP header and data.

 The Transmission Control Protocol
TCP performance is often dependent on a subset of algorithms and techniques such as flow control and congestion control.
All TCP segments carry a checksum, which is used by the receiver to detect errors with either the TCP header or data.
Flow control is a technique whose primary purpose is to properly match the transmission rate of sender to that of the receiver and the network.

 RFC 793 (rfc793) - Transmission Control Protocol   (Site not responding. Last check: 2007-10-21)
TCP also provides a means to communicate to the receiver of data that at some point further along in the data stream than the receiver is [Page 12] September 1981 Transmission Control Protocol Philosophy currently reading there is urgent data.
TCP does not attempt to define what the user specifically does upon being notified of pending urgent data, but the general notion is that the receiving process will take action to process the urgent data quickly.
TCP implementors may violate the "quiet time" restriction, but only at the risk of causing some old data to be accepted as new or new data rejected as old duplicated by some receivers in the internet system.

 Transmission Control Protocol
TCP is defined in [RFC 793], [RFC 1122], [RFC 1323], [RFC 2018] and [RFC 2581].
TCP's reliable data transfer service ensures that the data stream that a process reads out of its TCP receive buffer is uncorrupted, without gaps, without duplication, and in sequence, i.e., the byte stream is exactly the same byte stream that was sent by the end system on the other side of the connection.
TCP acknowledges data that has been received correctly, and retransmits segments when segments or their corresponding acknowledgements are thought to be lost or corrupted.

 Transmission Control Protocol
Transmission Control Protocol (TCP) is a means for building a reliable communications stream on top of the unreliable packet Internet Protocol (IP).
It is calculated by prepending a pseudo-header to the TCP segment, this consists of 3 32 bit words which contain the source and destination IP addresses, a byte set to 0, a byte set to 6 (the protocol number for TCP in an IP datagram header) and the segment length (in words).
A TCP connection is opened by a three-way handshake to establish a common view of the sequence numbers.

 Define TCP - a definition from Whatis.com - see also: Transmission Control Protocol
TCP (Transmission Control Protocol) is a set of rules (protocol) used along with the Internet Protocol (IP) to send data in the form of message units between computers over the Internet.
TCP is known as a connection-oriented protocol, which means that a connection is established and maintained until such time as the message or messages to be exchanged by the application programs at each end have been exchanged.
TCP is responsible for ensuring that a message is divided into the packets that IP manages and for reassembling the packets back into the complete message at the other end.

 TCP (Transmission Control Protocol) (Linktionary term)
TCP and UDP (User Datagram Protocol) are transport layer components that provide the connection point through which applications access network services.
TCP is a connection-oriented protocol that provides the flow controls and reliable data delivery services listed next.
TCP is described in RFC 793 (Transmission Control Protocol, September 1981).

 What is TCP? - A Word Definition From the Webopedia Computer Dictionary
TCP is one of the main protocols in TCP/IP networks.
Whereas the IP protocol deals only with packets, TCP enables two hosts to establish a connection and exchange streams of data.
TCP guarantees delivery of data and also guarantees that packets will be delivered in the same order in which they were sent.

 TCP/IP, Transmission Control Protocol / Internet Protocol
Four increasingly better versions of TCP/IP were developed -- TCP v1, TCP v2, a split into TCP v3 and IP v3 in the spring of 1978, and then stability with TCP v4 and IPv4 -- the standard protocol still in use on the Internet today.
The TCP/IP protocol was deployed to the ARPANET network with some persuasion, as noted in the emails at the top of the page.
Not all sites were preparing to convert over their protocols, so Cerf, Jon Postel, and the TCP/IP team turned off the NCP network channel numbers on the ARPANET IMP's for a full day in mid 1982, so that only sites using TCP/IP could still operate.

 Model Library: TCP   (Site not responding. Last check: 2007-10-21)
Transmission Control Protocol (TCP) is a widely used connection-oriented transport layer protocol that provides reliable packet delivery over an unreliable network.
The TCP standard model is designed to be used with the IP standard model; however, it could also be modified for use with other network layer protocols
OPNET's finite state machine (FSM) representation of the TCP protocol is taken directly from the TCP RFC protocol description, and provides the model developer with tremendous flexibility in developing protocol models.
