What transport services does TCP provide?

TCP provides connection-oriented transmission services. TCP (Transmission Control Protocol) is a connection-oriented, reliable, byte stream-based transport layer communication protocol. In principle, TCP should be able to operate on top of a variety of communications systems, from hardwired connections to packet-switched or circuit-switched networks.

Related introduction:

Transmission Control Protocol (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. TCP is relied upon to provide reliable communication services between pairs of processes in a host computer connected to different but interconnected computer communication networks. TCP assumes that it can obtain simple, possibly unreliable datagram services from lower-level protocols.

In principle, TCP should be able to operate on top of a variety of communications systems, from hardwired connections to packet-switched or circuit-switched networks.

Main features:

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

(1) Stream-based method;

(2) Connection-oriented;

(3) Reliable communication method;

(4) In When the network condition is poor, try to reduce the system's bandwidth overhead caused by retransmission;

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