UDP Applications

UDP Applications


The following shows some typical applications that can benefit more from the services of UDP than from those of TCP.

UDP is suitable for a process that requires simple request-response communication with little concern for flow and error control. It is not usually used for a process such as FTP that needs to send bulk data.

UDP is suitable for a process with internal flow and error-control mechanisms. For
example, the Trivial File Transfer Protocol (TFTP) process includes flow and error control. It can easily use UDP.

UDP is a suitable transport protocol for multicasting. Multicasting capability is
embedded in the UDP software but not in the TCP software.

UDP is used for management processes such as SNMP.

UDP is used for some route updating protocols such as Routing Information Proto-
col (RIP).

UDP is normally used for real-time applications that cannot tolerate uneven delay
between sections of a received message.
