Uses of UDP

We know that UDP is a connectionless and unreliable protocol. Then what are the uses of it?

Even though UDP is a connectionless and unreliable protocol there are certain uses.

1)A short message that does not bother about reliability can be transmitted very fastly by using UDP. Since in UDP there's no overhead of establishing and terminating a connection.

2)Network management protocols like SNMP uses UDP.

3)UDP is used by protocols that have inbuilt flow and error control mechanisms. EX: TFTP

Comparison between TCP and UDP
If you were to compare User Datagram Protocol (UDP) with TCP, the former is basically the scaled-down economy model that’s sometimes referred to as a thin protocol. Like a thin person on a park bench, a thin protocol doesn’t take up a lot of room—or in this case, much bandwidth on a network.

Another circumstance calling for UDP over TCP is when reliability is already handled at the Process/Application layer (in DoD Model).

TCP is for reliability while UDP for faster transfers.

1. UDP would be most suitable for real time applications such as video conferencing since congestion control, as in TCP,would be damaging for such applications !!

2. UDP is good for sending messages from one system to another when the order isn't important and you don't need all of the messages to get to the other machine.
