Multiswitching

In multiswitching will understand the using of this kind of switch in a backbone of the networks.

Also known as a core switch and a tandem switch, a backbone switch is a high-capacity switch positioned in the physical core, or backbone, of a network. In the context of a public wide area network (WAN), a backbone switch serves to interconnect edge switches, which are positioned at the network edge, and does not connect to desktop machines or other end user terminals.

See also core switch, LAN, switch, tandem switch,WAN, and workgroup switch.

The backbone network is an important architectural element for building enterprise networks. It provides a path for the exchange of information between different LANs or subnetworks. A backbone can tie together diverse networks in the same building, in different buildings in a campus environment, or over wide areas. Generally, the backbone's capacity is greater than the networks connected to it.

There are distributed backbones that snake throughout a building or campus to provide a connection point for LANs, and there are collapsed backbones that exist as wiring hubs and switches. The two topologies are illustrated in Figure B-1. A hybrid configuration ties together several collapsed backbone hubs or switches with a distributed backbone.
