Document Summary
The naional science foundaion sill pays for large porion of the internets ifnrastructue and funds research and development. The main paths of the internet along which data travels the fastest are known collecively as the internet backbone collecion fo large naional and internaional networks owned by organizaions. A backbone is typically a high speed ibe line designated as an opical carrier (oc) line. A t line carried digital data over twisted pair wireless. Isp like verizon and comcast are connected toether through an internet exchange point (ixp) made up of one or more network switches to which isps connect.
