Reality check

This week's netflow for the Internet 2
 
http://netflow.internet2.edu/weekly/20041025/

has BitTorrent taking up about 4.8 % of the traffic, http is 15 to 18%, and all
file sharing is about 10%, down from 50% 2 years ago.

Since file sharing and related uses are generally heavy traffic sources on I2, I would conclude
that the Reuter's numbers are too high. 

Not really,

Most popular bittorrent websites force you to use ports other than 6881.
So netflow reports are inaccurate.
My guess is that you could account a large chunk of 31.59% Unidentified
to bittorrent.
