| The '''Internet backbone''' was the central network that linked all the parts of the ] together. The term is now used as a loose term to describe the "core" of the current Internet. | |||
| ==History== | |||
| The original Internet backbone was the ]. | |||
| In ] the ] backbone was established, the US military broke off as a separate ] network, and the ARPANET was shut down. | |||
| A plan was then developed for first expanding NSFNet further, prior to rendering it obsolete by creating a new network architecture based on decentralized routing. <!--(to be written: creation of the NAPs, ])--> | |||
| With the decommissioning of the NSFNet Internet backbone network on ], ], the Internet now consists entirely of the various commercial ]s and private networks (as well as inter-university networks), as connected at their ] points. | |||
| The term "Internet backbone" is now sometimes loosely used to refer to the inter-provider links and peering points. However, with the universal use of the ] ], the Internet functions with no single central network at all. | |||
| With the advent of the ] of ], a number of major telecommunications carriers were threatened by bankruptcy, and some failed completely: for example, the ] network was decomissioned in its entirety. This was a successful test of the level of fault-tolerance and redundancy of the Internet. | |||
| ==Overview== | |||
| The Internet backbone consists of many different ]s. Usually, the term is used to describe large networks that inter-connect with each others and have individual ISPs as clients. For example, a local ISP may provide service for a single town, and connect to a regional provider which has several local ISPs as client. This regional provider connects to one of the backbone networks, which provides nationwide or worldwide connections. | |||
| These backbone providers usually provide connection facilities in many cities for their clients, and they themselves connect with other backbone providers at ]s such as ] in ] or ] in ]. | |||
| Backbone networks are usually commercial, educational or government owned, such as military networks. Some large companies that provide backbone connectivity include ], ], ], ] and ]. | |||
