The UDP is one of the main protocols of the Internet protocol suite.
With UDP, systems can send messages or datagrams to other hosts on an IP network.
UDP is a simple connection-less communication model with a minimum of protocol mechanisms. It has no handshaking dialogues; there is no guarantee of delivery, ordering, or duplicate protection.
If error-correction facilities are needed at the network interface level, an application may instead use Transmission Control Protocol (TCP) or Stream Control Transmission Protocol (SCTP), designed for this purpose.Back to Glossary
