* = >0 but <0.5% mb = megabits per second; gb = gigabits per second ^aFigures for 2010 are estimated. NOTES: Details may not add to 100% due to rounding. Internet1, also termed commodity internet, is the general public, multiuse network often called the "Internet." Internet2 is a high-performance backbone network that enables the development of advanced Internet applications and the deployment of leading-edge network services to member colleges, universities, and research laboratories across the country. Total bandwidth for FY 2009 and 2010 includes National LamdaRail bandwidth. The response categories in the FY 2005 survey varied slightly from those in the FY 2007 and 2009 surveys; in the FY 2005 survey, the categories were "1 to 2.5 gb" and "2.6 to 9 gb."
