A network switch is a device that provides a switching function in a data communications network. A network switch routes data transmissions such as ethernet packets between a set of network buses. Network switches, such as Ethernet switches, allow simultaneous connections between pairs of devices on a network and remarkably improve the bandwidth of a network compared with non-switching techniques, such as hubs which use a physically or logically common medium. A data network switch permits data communication among a plurality of media stations in a local area network. Data frames or packets, are transferred between stations by means of data network switch media access controllers. A network switch creates a network among a plurality of end nodes connected to one port of the network. The ports also serve to connect network switches together. Each end node sends packets of data to the network switch which the switch then routes either to another of the end nodes connected thereto or to a network switch to which the destination end node is connected. A network switch has several input and output ports for receiving and forwarding data transmission. Each input port may be linked to a network station or to a port of another network switch. A typical network switch also includes a crosspoint switch or other routing device which selectively routes packets between the network switch's input and ports. A digital switch typically has physical ports that are configured to communicate using different protocols at different data rates.
