User Datagram Protocol is one of the core members of the Internet Protocol Suite, along with TCP. The main principle in the concept of UDP is that ordering, reliability and so on are not important. The application will itself perform all the checks if necessary. Thus the protocol is very lightweight.
Datagrams are what is used to send/receive data in UDP. They have but the basic information in headers, enough to route datagram to recipient without prior knowledge of how previous datagrams were sent. Datagrams allow the quickest protocols at the cost of all the processing required to get all the required information from datagrams received. Datagrams can also be used for the most lightweight and quick monitoring, if only a host presence and/or ability to connect are important.

TCP monitoring makes sense when we should make sure the connection to a given IP address at a given port is possible. Manual TCP connectivity monitoring is made most often with telnet program; if the host responds, then the test is positive. However, in case we have a multitude of hosts and ports to test, manual checking becomes too cumbersome …
