P2P Remains Dominant Protocol
An anonymous reader writes "Last week, a press release was issued by Ellacotya that suggested something quite startling — HTTP (Hyper Text Transfer Protocol, aka Web traffic) had for the first time in four years overtaken P2P traffic. However a new article from Slyck disputes this, and contends that P2P remains the bandwidth heavyweight."
P2P is not one protocol, but many. Some P2P systems, such as Gnutella, even use HTTP for file transfers.
