''How much of the traffic on the internet is peer-to-peer file trading?
Everyone seems to agree it represents a lot of the traffic, but the truth is no one knows (with the possible exception of the ISPs and backbone providers in the middle, and they aren't telling or sharing raw data).
One of the most recent reports on P2P traffic came from a traffic optimization firm called Ellacoya in June 2007. Their report said that http-based web traffic had overtaken peer-to-peer traffic on the net, thanks to streaming media sites like YouTube.''
