Hi all,

I came across the report by Sandvine this week:
http://www.sandvine.com/news/global_broadband_trends.asp .

It details upstream and downstream bandwidth use and essentially says
that upstream, p2p has a 61% share (there's no web media downstream),
while downstream Web Media has a 15.7% share and p2p a 22.31% share.

This gives us a nice background on the relvance of protocols, e.g.
VoIP only has 5.38% share in upstream and is gathered among others in
downstream.

There is a problem with the report though. It shows how much bandwidth
is used by the protocols. But it doesn't show how many users use these
protocols. Since p2p is most often used for large files, I am assuming
that the number of users of p2p is massively smaller than the number
of users of Web media. And streaming seems to not make much impact at
all.

Anyway - I thought it's a good statistic to share.

Cheers,
Silvia.
