connectionless protocol


The data communication method in which communication occurs between hosts with no previous setup. Packets sent between two hosts may take different routes.

UDP is a connectionless protocol. Also called packet switching. Contrast circuit switching, connection-oriented.

Lisp with a parallel data structure, the 'xapping', an array of values assigned to an array of sites.

(Or connection-based, stream-oriented). A type of transport layer data communication service that allows a host to send data in a continuous stream to another host. The transport service will guarantee that all data will be delivered to the other end in the same order as sent and without duplication. Communication proceeds through three well-defined phases: connection establishment, data transfer, connection release. The most common example is Transmission Control Protocol (TCP), another is ATM.

The network nodes at either end needs to inform all intermediate nodes about their service requirements and traffic parameters in order to establish communication.

Opposite of connectionless, datagram. See also circuit switching, packet switching, virtual circuit.

connection-oriented network service


(CONS) Because of the relatively long transit delays and inferior bit error rate of WANs, a more sophisticated connection-oriented protocol is normally used.
