UDP

UDP

One of the important protocols in the TCP/IP site is User Datagram Protocol (UDP). UDP is basically a scaled-down version of TCP. Just like TCP, this protocol provides delivery of data between applications running on hosts on a TCP/IP network, unlike TCP, it does not sequence the data and does not care about the order in which the segments arrive at the destination. Because of this it is considered to be an unreliable protocol. UDP is also considered to be a connection-less protocol, since no virtual circuit is established between two endpoints before the data transfer takes place.

UDP application

Here are few applications where UDP is used to transmit data:

Domain Name Services

Simple Network Management Protocol

Trivial File Transfer Protocol

Routing Information Protocol

Kerberos
