What kind of protocol does udp protocol refer to in tcp/ip protocol
This article mainly introduces what the udp protocol in the tcp/ip protocol refers to. It is very detailed and has a certain reference value. Interested friends must read it!
In tcp/ip protocol, udp protocol is a kind of transport protocol; udp protocol is an unreliable connectionless protocol, which is mainly used in transmissions that do not require the arrival of packets sequentially, and the packet transmission order is checked and sorted by the application layer.
In TCP/IP protocol, UDP protocol belongs to the transport layer.
The transport layer of the TCP/IP model defines two protocols: transmission Control Protocol (TCP) and user Datagram Protocol (UDP). UDP protocol is an unreliable connectionless protocol, which is mainly used in transmissions where packets are not required to arrive sequentially. The packet transmission order is checked and sorted by the application layer.
Related introduction:
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.
