Connectionless-mode Network Service

<p>Connectionless-mode Network Service (CLNS) or simply Connectionless Network Service is an <a href="/facts/OSI_protocols/MEEwuPY1">OSI network layer</a> <a href="/facts/Datagram/TMHVctMz">datagram service</a> that does not require a circuit to be established before data is transmitted, and routes messages to their <a href="/facts/NSAP_address/Hbt1b7cC">destinations</a> independently of any other messages. As such it is a "<a href="/facts/Best-effort_delivery/W0JBRbtH">best-effort</a>" rather than a "<a href="/facts/Reliability_(computer_networking)/v3kGvfvs">reliable</a>" delivery service. CLNS is not an <a href="/facts/Internet/Xw1rVvJU">Internet</a> service, but provides capabilities in an <a href="/facts/OSI_model/oxN9Xhjz">OSI network environment</a> similar to those provided by the <a href="/facts/Internet_protocol_suite/KNkxtSpw">Internet protocol suite</a>.  The service is specified in ISO/IEC 8348, the OSI Network Service Definition (which also defines the connection-oriented service, CONS.)
