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 network switch is a multiport network bridge that uses MAC addresses to forward data ...
Donald Davies' work on data communications and computer network design became well known in the United States, Europe and Japan and was the "cornerstone" that inspired numerous packet switching networks in the decade following.
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.
Networking hardware, also known as network equipment or computer networking devices, are electronic devices that are required for communication and interaction between devices on a computer network. Specifically, they mediate data transmission in a computer network. [ 1 ]
In computer networking, cut-through switching, also called cut-through forwarding [1] is a method for packet switching systems, wherein the switch starts forwarding a frame (or packet) before the whole frame has been received, normally as soon as the destination address and outgoing interface is determined.
Circuit switching originated in analog telephone networks where the network created a dedicated circuit between two telephones for the duration of a telephone call. [2] It contrasts with message switching and packet switching used in modern digital networks in which the trunklines between switching centres carry data between many different ...
Switching loops can cause misleading entries in a switch's media access control (MAC) database and can cause endless unicast frames to be broadcast throughout the network. A loop can make a switch receive the same broadcast frames on two different ports, and alternatingly associate the sending MAC address with the one or the other port.
Broadly, routing is performed in many types of networks, including circuit-switched networks, such as the public switched telephone network (PSTN), and computer networks, such as the Internet. In packet switching networks, routing is the higher-level decision making that directs network packets from their source toward their destination through ...
