TCP / IP is a lot of different protocols, actually a protocol group, TCP user data report protocol (also known as TCP Transmission Control Protocol, TRANSPORT Control Protocol Reliable Host To Host Level Agreement. Here you must first emphasize. The transfer control protocol is a fourth layer of the OSI network, and the TCP transmission control protocol is one of the six basic protocols of TCP / IP transmission. The two TCP means that it is not the same.). TCP is a reliable connection-oriented delivery service. It is diverted when transmitting data, and host exchange data must establish a session. It communicates with bitstream, that is, data is used as a structural stream. The sequence number is specified by the field transmitted by each TCP to obtain reliability. Is the fourth layer in the OSI reference model, TCP is a network interconnection function using IP to provide reliable data transmission, and IP is constrained on the network, while TCP is responsible for confident packets. In the operation of collaborative IP, TCP is responsible for: Handshake Process, Message Management, Flow Control, Error Detection, and Processing (Control), which can be given from new arrangements from new arrangements depending on a certain number of order sequences. About the RFC document of TCP has RFC793, RFC791, RFC1700.
