Metropolitan Area NetworksMetropolitan Area Networks (MAN) are intended to cover larger geographical locations that range from a number of buildings to the areas of whole cities. Examples of metropolitan area networks of many sizes can be discovered in the metropolitan areas of London, England Lodz, Poland and Geneva, Switzerland. When covering the footprint of a complete town Metropolitan Area Networks (MAN) can act as an alternative access technology for the last mile industry (e.g. broadband wireless access to the World-wide-web). With DQDB, networks can extend up to 20 miles (30 km) extended and operate at speeds of 34-155 Mbit/s.

Personal computer networks can be characterized in the term of the geographic area they occupy and the purpose of the network within this geographic location. A wide region network, or WAN, occupies a pretty massive region, such as an whole nation or the whole globe. Most data are collected, transmitted, and stored through cellular networks that continue to expand an ever increasing coverage region over the years. The HiperMAN specifications have been developed by ETSI Technical Committee Broadband Radio Access Networks (TC BRAN).

Devices with WAP functionality deliver a bridge involving computer systems and networks. Wireless networks can often handle a bigger amount of customers due to the fact they are not limited by a precise quantity of connection ports. Networks can cover something from a handful of devices inside a single room to millions of devices spread across the entire globe.

In the occasion that you have a lot of smaller networks all linked together into a significant wide location network, and that configuration is owned by a single business or single organization, then that kind of a network is often referred to as an enterprise network. For instance, Metropolitan Area Networks (MAN) can cover a university campus where they act as … Continue reading >>>

Backbone NetworksA collapsed backbone (inverted backbone, backbone-in-a-box) is a form of backbone network architecture. This sort of network can have daisy chain linked devices for the backbone, nonetheless, designer really should think about the same limitations as for the serial backbone. It is as fast as a bridge for similar information link sort networks, but can also connect distinctive data hyperlink variety networks. The idea behind switched ethernet – and all switched media technologies – is straightforward replace the LAN hub with a switch.

Each and every of these LANs and WLANs are connected into a switch for that floor, therefore forming a switched backbone on each and every floor. Each of these ATMs appear to be excellent options for desktop connections when ATM backbone networks are made use of. The technologies operate by giving a high speed circuit that is shared among all computer systems on the LAN or backbone network.

In the switched backbone design and style as shown in Figure 8.6, for example,all the computers in the exact same general physical location are connected to the same switch and therefore share the capacity of the switch. Some tiny organizations are not significant enough to have a core layer their backbone spans only the distribution layer. Due to the fact the backbone is essentially the back plane or internal switching matrix of the box, proprietary, higher functionality technology can be utilized.

A large corporation that has a lot of places may perhaps have a backbone network that ties all of the locations collectively, for instance, if a server cluster requirements to be accessed by diverse departments of a organization that are located at unique geographical locations. The World wide web has enabled or accelerated new types of human interactions via immediate messaging, Web forums, and social networking. Distributed backbone … Continue reading >>>
