(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. |
