The communication of systems in local home and corporate networks as well as public networks such as the internet is based by default on the internet protocol family. The most well-known component of this protocol stack is undoubtedly the Internet Protocol (IP), which is not only responsible for addressing and fragmenting data packets, but also defines how information about source and destination is described. However, the transmission of data is usually handled by the connection-oriented Transmission Control Protocol (TCP), which is why networks are often referred to as TCP/IP networks. Because TCP provides security but also delays transmission, David Patrick Reed published his User Datagram Protocol (UDP) concept in 1980 as a simpler and faster alternative to the standard protocol.
