Reality check
This week's netflow for the Internet 2
Netflow is based on port numbers and many run bittorrent on fairly
random ports. Look at the 30%+ unidentified on the report.

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.

For those not familiar, BitTorrent is a file sharing app that is
commonly
used for exchanging full movies. As such, folks are moving gigabyte
files regularly and it's not surprising that this is detectable.
Shuffling .mp3's around would be trivial by comparison.

According to Reuters, BT is more traffic than web/other forms of
traffic? I'm thinking the sampling methodology here might be a little
skewed.
1) where was the measurement done?
2) how was the measurement done?
3) what population was sampled?
On some networks BT might account for far more than 30%, on others far,
far less... Perhaps the writers will answer?
