Types Of Backbone Networks
A 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.

For this cause, gigabit ethernet may well stay primarily a backbone technologies for use only in point-to-point full duplex data communications hyperlinks. Asynchronous Transfer Mode (ATM) (a.k.a. cell relay) is a technologies originally made for use in wide location networks that is now normally employed in backbone networks. It could also be known as an enterprise network if it connects all networks within a organization.
As soon as the virtual circuit is prepared, the LAN packet is broken into the series of ATM cells, and transmitted over … Continue reading >>>
