Internet backbone
The superfast network spanning the world, from one major metropolitan area to another. It is supported by a handful of Internet Service Providers (ISPs). These companies and organizations use connections that run at approximately 45MB per second (T3 lines) and are linked at specified interconnection points called "national access points" or "regional nerve centers." Local ISPs connect to this backbone through routers so data can be sent and received though the backbone.
