What is the network protocol tcp?

tcp (Transmission Control Protocol) is a connection-oriented, reliable, byte stream-based transport layer communication protocol. TCP is designed to accommodate a layered protocol hierarchy that supports multiple network applications.

Transmission Control Protocol (TCP, Transmission Control Protocol) is a transmission protocol specially designed to provide reliable end-to-end byte streams on unreliable Internet networks.

The formal definition of TCP is given by RFC793 in September 1981. Over time, many improvements have been made to it, and various bugs and inconsistencies have been gradually fixed.

TCP is a communication protocol for wide area networks. Its purpose is to provide a communication method between two communication endpoints with the following characteristics when communicating across multiple networks:

(1 ) Stream-based method;

(2) Connection-oriented;

(3) Reliable communication method;

(4) Try to reduce the system speed when the network condition is poor Due to the bandwidth overhead caused by retransmission;

(5) Communication connection maintenance is oriented to the two endpoints of communication, without considering intermediate network segments and nodes.
