Backbone NetworksA backbone is the portion of the computer network infrastructure that interconnects unique networks and provides a path for exchange of data in between these different networks. Backbone networks may well themselves be multilevel, incorporating low-capacity terrestrial links, higher-capacity terrestrial links, and satellite links. This ring could represent the minimum cost of WAN circuits, compromised by an initial estimate of big site visitors flows, and possibly some extremely certain delay requirements (though this is uncommon, with notable exceptions getting higher-overall performance networks). Even though there are an infinite quantity of techniques in which network designers can build backbone networks, there are genuinely only 3 fundamental architectures that can be combined in diverse methods.

There is a switch serving every LAN (access layer) which is connected to the backbone switch at the bottom of the figure (distribution layer). For the reason that you have a simple want for resilience in the backbone, a excellent starting point for the backbone topology is a ring connecting all distribution networks. One approach to delivering high speed networks is to create more rapidly versions of the same technology applied in LANs.
