Which layer does the udp protocol work on in the computer?

This article mainly introduces the computer udp protocol work layer is which layer, the article is very detailed, has a certain reference value, interested friends must read it!

The layer where the udp protocol works is at the transport layer. Udp protocol (user Datagram Protocol) is a connectionless transport protocol that provides applications with a way to send encapsulated IP packets without establishing a connection.

In the TCP/IP suite, the UDP protocol works at the transport layer.

TCP/IP protocol is divided into four layers, including network interface layer, internetwork layer, transport layer and application layer from bottom to top. The main function of the transport layer is to segment the user information transmitted by the application layer and add some additional instructions to ensure that the other party receives reliable information. There are two protocols in this layer, namely, Transmission Control Protocol (TCP) and user packet Protocol (UDP).

The Internet protocol set supports a connectionless transport protocol called user Datagram Protocol (UDP,User Datagram Protocol). UDP provides an application with a way to send encapsulated IP packets without establishing a connection. RFC 768 describes UDP.

The transport layer of Internet has two main protocols that complement each other. Connectionless is UDP, which does little more than send packet functionality to applications and allow them to structure their own protocols at the desired level. The connection-oriented is TCP, which does almost everything.
