To be able to understand what an Internet backbone is, let us remind what the Internet is and why we do need it.
The Internet is a global network of interconnected computers, enabling users to share information along multiple channels. Typically, a computer that connects to the Internet can access information from a vast array of available servers and other computers by moving information from them to the computer’s local memory. The same connection allows the computer to send information to servers on the network; that information is in turn accessed and potentially modified by a variety of other interconnected computers. A majority of widely accessible information on the Internet consists of inter-linked hypertext documents and other resources of the World Wide Web (WWW). Computer users typically manage sent and received information with the help of web browsers. The end-users have no full control of all information. The service provider could block certain information from the end-users. Other software for users’ interface with computer networks includes specialized programs for electronic mail, online chat, file transfer and file sharing. Among further things the Internet has some common use in e-mail, the world wide web, remote access, collaboration, file sharing, streaming media, Internet telephony (VoIP).
In order to enable proper access to some of the Internet’s uses, the Internet backbone is necessary. The Internet backbone refers to the main “trunk” connections of the Inernet. It is made up of a large collection of interconnected data routes of high capacity and core routers that carry data across the countries, continents and oceans, across the whole world. The Internet backbone consists of many different networks. Usually, the term is used to describe large networks that interconnect with each other and may have individual ISPs (Internet service provider) as clients. For example, a local ISP may provide service to individual homes or businesses using the bandwidth that it purchases from another company with the backbone network. The conditions for applying to become an Internet backbone service provider should be made simple to encourage competition, which will eventually drive down cost, create jobs and provide excellent service. Backbone networks are usually commercial, academic, educational, or government owned, such as military networks.
