Internet backbones

A group of communications networks managed by several commercial companies that provide the major high-speed links across the country. ISPs are either connected directly to these backbones or to a larger regional ISP that is connected to one. The backbones themselves are interconnected at various access points called "NAPs." The major backbone providers include Qwest, Level 3 Communications, AT&T, Sprint/Nextel, SAVVIS and British Telecom. See NAP.
