A portion of a personal computer network that is capable of carrying the majority of website traffic on the network at higher speeds. Backbone networks may themselves be multilevel, incorporating low-capacity terrestrial links, high-capacity terrestrial links, and satellite links. This ring could represent the minimum price of WAN circuits, compromised by an initial estimate of big traffic flows, and possibly some quite certain delay needs (despite the fact that this is uncommon, with notable exceptions becoming higher-efficiency networks). Although there are an infinite number of methods in which network designers can construct backbone networks, there are really only 3 fundamental architectures that can be combined in distinct ways.
The core layer is the element of the backbone that connects the distinct BNs with each other, often from constructing to building. The pieces of the network connections (for example: ethernet, wireless) that bring these departments collectively is typically described as network backbone. Of course the capacity of the backbone is supposed to be greater than that of the networks it serves.
Each of these LANs and WLANs are connected into a switch for that floor, thus forming a switched backbone on each floor. Each of these ATMs appear to be superior alternatives for desktop connections when ATM backbone networks are utilized. The technologies operate by offering a high speed circuit that is shared amongst all computer systems on the LAN or backbone network.
In the above image, performed by Donna Cox and Robert Patterson of the NCSA, is a visual representation of what an Internet backbone in the United States. Most organizations now use switched backbones in which all network devices for 1 part of the developing are physically situated in the same room, often in a rack of gear. Routers connect two or extra LANs that use the very same or distinctive data hyperlink protocols, but the very same network protocol. The purpose of the backbone is to connect regional distribution networks and, in some instances, to supply connectivity to other peer networks.
Efficiency and Scalibility: the backbone will have to have a much greater bandwidth than the access networks feeders. Strictly speaking, hubs are not considered portion of a backbone network, but are normally repeaters or amplifiers. This kind of backbone is very easily scalable considering the fact that new layers of devices can be added with no troubles. A backbone network is a higher speed network that connects quite a few networks in a single corporation or government site.
