Datagram A datagram is a basic transfer unit associated with a packet-switched network. The delivery, arrival time, and order of arrival need not be guaranteed by the network. == History == The term ''datagram'' appeared first within the project CYCLADES, a packet-switched network created in the early 1970s, and was coined by Louis Pouzin〔("Postel and Pouzin: 1997 SIGCOMM Award Winners" ), ACM SIGCOMM web site〕 by combining the words ''data'' and ''telegram''. CYCLADES was the first network to make the hosts responsible for the reliable delivery of data, rather than the network itself, using unreliable datagrams and associated end-to-end protocol mechanisms. These concepts were later adopted for the creation of the Internet Protocol (IP) and other network protocols.
