Reed in 1980 and formally defined in RFC 768. UDP is sometimes called the Universal Datagram Protocol. With UDP, computer applications can send messages, sometimes known as datagrams, to other hosts on an Internet Protocol (IP) network without requiring prior communications to set up special transmission channels or data paths. The User Datagram Protocol (UDP) is one of the core members of the Internet Protocol Suite, the set of network protocols used for the Internet. Among its management tasks, TCP controls message size, the rate at which messages are exchanged, and network traffic congestion. Besides the Web, other common applications of TCP include e-mail and file transfer. In particular, TCP provides reliable, ordered delivery of a stream of bytes from one program on one computer to another program on another computer. TCP is so central that the entire suite is often referred to as "TCP/IP." Whereas IP handles lower-level transmissions from computer to computer as a message makes its way across the Internet, TCP operates at a higher level, concerned only with the two end systems, for example a Web browser and a Web server. The Transmission Control Protocol (TCP) is one of the core protocols of the Internet Protocol Suite. Such an endpoint is known as a port and the identifier is the port number. Use a numerical identifier for the data structures of the endpoints for host-to-host communications. In computer networking, the protocols of the Transport Layer of the Internet Protocol Suite, most notably the Transmission Control Protocol (TCP) and the User Datagram Protocol (UDP), The closest known UDP ports before 1167 port :1168 (VChat Conference Service), 1168 (VChat Conference Service), 1169 (TRIPWIRE), 1169 (TRIPWIRE), 1169 (Tripwire),

All ports should be closed or filtered, unless you specifically require some open (and know exactly what they are).
