User Datagram Protocol, or UDP, described in RFC 768, provides a connectionless, best-effort packet
delivery service. At first take, it may seem questionable that any application would prefer an unreliable
delivery over the connection-oriented TCP. The advantage of UDP, however, is that no time is spent
setting up a connection—the data is just sent. Applications that send short bursts of data will realize a
performance advantage by using UDP instead of TCP.
