Avaya ERS 2550T-PWR, a 50-port Ethernet switch. A network switch (also called switching hub, bridging hub, Ethernet switch, and, by the IEEE, MAC bridge [1]) is networking hardware that connects devices on a computer network by using packet switching to receive and forward data to the destination device.
A multilayer switch (MLS) is a computer networking device that switches on OSI layer 2 like an ordinary network switch and provides extra functions on higher OSI layers. The MLS was invented [ 1 ] by engineers at Digital Equipment Corporation .
X.25 is an ITU-T standard protocol suite for packet-switched data communication in wide area networks (WAN). It was originally defined by the International Telegraph and Telephone Consultative Committee (CCITT, now ITU-T) in a series of drafts and finalized in a publication known as The Orange Book in 1976.
In computer networking and telecommunications, a switched communication network is a communication network which uses switching for connection of two non-adjacent nodes. Switched communication networks are divided into circuit switched networks, message switched networks, and packet switched networks.
A fully switched network is a computer network which uses only network switches rather than Ethernet hubs on Ethernet networks. [1] The switches provide a dedicated connection to each workstation. A switch allows for many conversations to occur simultaneously.
The services and protocols specified in IEEE 802 map to the lower two layers (data link and physical) of the seven-layer Open Systems Interconnection (OSI) networking reference model. IEEE 802 divides the OSI data link layer into two sub-layers: logical link control (LLC) and medium access control (MAC), as follows:
A protocol like OpenFlow is needed to move network control out of proprietary network switches and into control software that's open source and locally managed. [ 8 ] A number of network switch and router vendors announced intent to support or are shipping supported switches for OpenFlow, including Alcatel-Lucent , [ 9 ] Big Switch Networks ...
In telecommunications, deterministic routing is the advance determination of the routes between given pairs of nodes. Examples: In a network where routing is controlled by a telephone switch or network switch, switching in which the routes between given pairs of nodes are pre-programmed, i.e., are determined, in advance of transmission.
