Backbone

Part of the network that joins several local-area networks, either inside a building or across a city or country. This is achieved through a cable connection between telecommunication or wiring closets, floor distribution terminals or entrance facilities. In star networks, the backbone cable interconnects hubs and similar devices, as opposed to cables running between hub and station. The backbone is the part of the communications network that carries the heaviest traffic.
