This article mainly introduces what are the main functions of tcp protocol, which can be used for reference by interested friends. I hope you will gain a lot after reading this article.

The main function of tcp protocol is to ensure the reliable transmission of data. TCP protocol is a connection-oriented, reliable, byte-stream-based transport layer communication protocol, which aims to adapt to the hierarchical protocol hierarchy that supports multi-network applications.

The main function of TCP protocol is to ensure the reliable transmission of data.

Transmission Control Protocol (TCP) provides reliable communication connections to applications by using retransmission technology and congestion control mechanism, so that it can automatically adapt to various changes on the Internet.

Transmission Control Protocol (TCP,Transmission Control Protocol) is a connection-oriented, reliable, byte-stream-based transport layer communication protocol defined by RFC 793of IETF.

TCP is designed to adapt to a hierarchical protocol hierarchy that supports multiple network applications. Paired processes in host computers connected to different but interconnected computer communication networks rely on TCP to provide reliable communication services. TCP assumes that it can obtain simple and possibly unreliable Datagram services from lower-level protocols. In principle, TCP should be able to operate on various communication systems connected from hardwires to packet-switched or circuit-switched networks.

Thank you for reading this article carefully. I hope the article "what are the main functions of tcp protocol" shared by the editor will be helpful to you. At the same time, I also hope that you will support us and pay attention to the industry information channel. More related knowledge is waiting for you to learn!
