* = > 0 but < 0.5%. na = not applicable; category was added to FY 2011 survey.

Gbps = gigabits/second; Mbps = megabits/second.

a Figures for 2012 are estimated.
b More than 20 Gbps is a subset of more than 10 Gbps.

NOTES: Detail may not add to total because of rounding. FYs 2009, 2011, and 2012 include bandwidth to Internet1 (also termed “commodity Internet”), Internet2, and National LambdaRail. Data for FY 2005 and FY 2007 are limited to Internet1 and Internet2. The response categories in the FY 2005 survey varied slightly from those in the FYs 2007–11 surveys; in the FY 2005 survey, the categories included “1–2.5 Gbps” and “2.6–9 Gbps.”
