Netflix takes up 9.5% of upstream traffic on the North American Internet

During peak viewing hours, Netflix accounts for about a third of all bits sent to Internet users in North America on “fixed” connections -- that is, cable, DSL, fiber, or satellite, but not cellular. But Netflix users also send a ton of data upstream, so much so that Sandvine’s latest Internet Phenomena Report puts Netflix at 9.48 percent of all peak upstream traffic on North American fixed Internet services, second only to BitTorrent's 25.49 percent. Sandvine, a maker of equipment that helps consumer broadband providers manage network congestion, defines “peak” hours as those when network usage is within 95 percent of its daily maximum, typically from 7 to 11 p.m.
