User Datagram Protocol (UDP)
(I) An Internet Standard protocol [R0768] that provides a datagram
mode of packet-switched computer communication in an internetwork.
(C) UDP is a transport layer protocol, and it assumes that IP is
the underlying protocol. UDP enables application programs to send
transaction-oriented data to other programs with minimal protocol
mechanism. UDP does not provide reliable delivery, flow control,
sequencing, or other end-to-end services that TCP provides.
