Backbone Networks

A backbone network allows several LANs to be connected. In a backbone network, no station is directly connected to the backbone; the stations are part of a LAN, and the backbone connects the LANs.A backbone network allows several LANs to be connected. In a backbone network, no station is directly connected to the backbone; the stations are part of a LAN, and the backbone connects the LANs. The backbone is itself a LAN that uses a LAN protocol such as Ethernet; each connection to the backbone is itself another LAN.

Although much different architecture can be used for a backbone, we discuss only the two most common: the bus and the star.Backbone LANs:

Because of increasing use of distributed applications and PCs, a new flexible strategy for LANs has been introduced. if a premises wide data communication system is to be supported then we need a networking system which can span over the required distance and which capable of interconnecting all the equipment in a single building or in a group of buildings.
