When in doubt, if you are looking for statistics about or on the Internet
start with www.caida.org.
caida website is undergoing restructuring for easier navigation
(yeah we'll be done any year now)
so in the meantime let me make this easier on you
also allow me to lower your standards (but raise your future expectations)
because we are in the process of setting up a better system for
regularly capturing and maintaining this type of data.
(blocked on hardware and software and some cool methodology
in development to do high speed flow estimation/analysis)
anyway so you may want to try the 3 links under
most recent in webpage form (not so recent)
for high-capacity backbone (san jose, california):
tabular view of same:
finally it's academic-ish locations (but hey that's where
all future application types start) and older data
(1998-2001, we're trying to update it w newer data
this spring, stay tuned) but try figure 7 of
(`Longitudinal study of Internet traffic from 1998-2001:
a view from 20 high performance sites')
sorry it's suboptimal but so is the current ability
to measure this sort of thing at a large
and arguably representative scale
but you knew that already
