Connectionless communication
open-in-new
<p>Connectionless communication, often referred to as CL-mode communication, is a data <a href="/facts/Transmission_(telecommunications)/33zk8a0A">transmission</a> method used in <a href="/facts/Packet_switching/olDlDP1R">packet switching</a> networks, using data packets that are frequently called <a href="/facts/Datagram/TMHVctMz">datagrams</a>, in which each data packet is individually addressed and routed based on information carried in each packet, rather than in the setup information of a prearranged, fixed data channel as in <a href="/facts/Connection-oriented_communication/2yAhgueh">connection-oriented communication</a>. Connectionless protocols are usually described as <a href="/facts/Stateless_protocol/TgJncyPa">stateless protocols</a>, the <a href="/facts/Internet_Protocol/Qq6VeEal">Internet Protocol</a> (IP) and <a href="/facts/User_Datagram_Protocol/dxLU0D6q">User Datagram Protocol</a> (UDP) are examples. </p>
