Ars Technica has an article titled "Sandvine: close to half of all bandwidth sucked up by P2P" where they write:
Almost half of all bandwidth in North America is made up of P2P traffic, according to Sandvine. The company, which develops deep packet inspection equipment to monitor broadband usage, says that P2P traffic is up about three percent from a year ago, going from 41 percent to almost 44 percent. P2P ate up an even larger chunk of upstream traffic, pushing regular old web traffic further down the list.
This seems low to me, since earlier reports indicate that up to 75 % of all internet traffic is made up by p2p. Interestingly, streaming is relatively minor, only about 14.8%. Which, again, is contrary to other reports. Oh, well, vendor stats....
