Packet switching — is a digital networking communications method that groups all transmitted data – regardless of content, type, or structure – into suitably sized blocks, called packets. Packet switching features delivery of variable bit rate data streams… … Wikipedia
packet switching — A data transmission method that simultaneously routes and transmits data packets from many customers over a communications channel or telephone line, thus optimizing use of the line. An addressed packet is routed from node to node until it… … Dictionary of networking
Packet radio — is a form of digital data transmission used to link computers. The most common use of PKT is in amateur radio, to construct wireless computer networks. Its name is a reference to the use of packet switching between network nodes, which allows… … Wikipedia
Packet switched network — A Packet Switched Network, or PSN, refers to the packet switched networks that existed before the Internet. The history of such networks can be divided into three eras:early networks before the introduction of X.25 and OSI,the X.25 era when many… … Wikipedia
Packet Switch Stream — In the UK, PSS, was an X.25 based packet switched network, provided by the British Post Office Telecommunications and then British Telecom from 1980, onwards. After a period of pre operational testing with customers (mainly UK Universities and… … Wikipedia
Packet switch — A packet switch is a node used to build a network which utilizes the packet switching paradigm for data communication. Packet switches can operate at a number of different levels in a protocol suite; although the exact technical details differ,… … Wikipedia
Switching center — A switching center is a node in a telecommunications Circuit switching network which is connected to either another switching center and/or to end user devices. Switching centers are aware of other centers and possible routes between them such… … Wikipedia
Node (networking) — For other uses, see Node (disambiguation). In communication networks, a node (Latin nodus, ‘knot’) is a connection point, either a redistribution point or a communication endpoint (some terminal equipment). The definition of a node depends on the … Wikipedia
Multiprotocol Label Switching — MPLS redirects here. For other uses, see Mpls. MPLS Layer Multiprotocol Label Switching (MPLS) is a mechanism in high performance telecommunications networks that directs data from one network node to the next based on short path labels rather… … Wikipedia
Circuit switching — is a methodology of implementing a telecommunications network in which two network nodes establish a dedicated communications channel (circuit) through the network before the nodes may communicate. The circuit guarantees the full bandwidth of the … Wikipedia
