Form of packet multiplexing characterized by the identification of individual channels based on global addressing. Hence, there are no predefined virtual circuits. As such, connectionless services use addressing that is of global significance.
A term used to describe data transfer that requires the establishment of a virtual connection.
Communications service where packets are transferred from source to destination without the need for a pre-established connection.
a communication model in which datagrams are transmitted to specified destinations
Term used to describe data transfer without the existence of a virtual circuit. Compare with connection-oriented. See also virtual circuit.
network A network over which an application or process can directly send and receive data one packet at a time without having to first set up a session or connection. A connectionless network is also referred to as a packet-oriented network or datagram network. A protocol can also be connectionless.
A communication process that takes place without first establishing a connection.
A network protocol in which a sender broadcasts traffic on the network to an intended receiver without first establishing a connection to the receiver.
No connection or pipe is established between two computers. (Novell 2-1)
Mode of communication in which a connection (circuit or logical channel) does not need to be set up for data transmission between the transmitter and receiver. It is the underlying protocol for packet-switched transmission. The individual data packets can go from the transmitter to the receiver via different paths. A well-known connectionless protocol is UDP.
The data communication method in which communication occurs between hosts with no previous setup. Packets between two hosts may take different routes, as each is independent of the other. UDP is a connectionless protocol. See also: circuit switching, connection-oriented, packet switching, User Datagram Protocol.
The model of interconnection in which communication takes place without first establishing a connection. UDP, IP, and IPX are connectionless protocols.
A type of network service that does not send acknowledgments upon receipt of data to the sender. UDP is a connectionless protocol.
Refers to the exchange of data without prior coordination between the transmitting and receiving devices.
The model of interconnection in which communication takes place without first establishing a connection. Sometimes (imprecisely) called datagram. Examples: Internet IP and OSI CLNP, UDP, ordinary postcards.
A mode of communication where no connection is established prior to the data transfer; the data transfer itself is a self contained unit carrying all information, such as addresses, etc.
Transmissions that do not require a direct connection prior to the transmission. Source and destination addresses are included in each packet.
