Transmission Control Protocol definition networking, protocol
(TCP) The most common transport layer protocol
used on Ethernet
and the Internet
. It was developed by DARPA
TCP is the connection-oriented
protocol built on top of Internet Protocol
(IP) and is nearly always seen in the combination TCP/IP
(TCP over IP). It adds reliable communication
and flow-control and provides full-duplex
, process-to-process connections.
TCP is defined in STD 7 and RFC
793. User Datagram Protocol
is the other, connectionless, protocol that runs on top of IP.
