| a method of efficient data transmission whereby the initial message is broken into relatively small units that are routed independently and subsequently reassembled. |
| packet switching n. A method of data transmission in which small blocks of data are transmitted rapidly over a channel dedicated to the connection only for the duration of the packet's transmission. |
packet switching communications
A communications paradigm in which packets (messages or fragments of messages) are individually routed between nodes, with no previously established communication path. Packets are routed to their destination through the most expedient route (as determined by some routing algorithm). Not all packets travelling between the same two hosts, even those from a single message, will necessarily follow the same route.
The destination computer reassembles the packets into their appropriate sequence. Packet switching is used to optimise the use of the bandwidth available in a network and to minimise the latency. X.25 is an international standard packet switching network.
Also called connectionless. Opposite of circuit switched or connection-oriented. See also virtual circuit, wormhole routing.
