Netflix represents 32.7% of North America's peak Web traffic

Despite losing 800,000 members, Netflix still accounts for a whopping 32.7% of all North American peak fixed access downstream traffic, according to Sandvine's fall 2011 Global Internet Phenomena Report. That's up nearly 10% since spring 2011 and almost double the peak traffic of the next largest source, HTTP at 17.5%.
Netflix pumps nearly three times as much bandwidth as YouTube and it accounts for 29% of peak aggregate traffic, ahead of HTTP's 16.6% and BitTorrent's 13.5%. In fact, the only statistics not dominated by Netflix are upstream-related. It's responsible for 7.7% of upload traffic, behind HTTP's 11.5% and BitTorrent's 47.6%.
As evidenced by its loss of nearly a million subscribers, Netflix has been treading some harsh water in recent months following several unpopular decisions. While this has prompted many to question the company's future, Sandvine doesn't foresee a significant decline in the service's traffic because it's so widely available.
"With so many Netflix-capable devices, the addressable market of the service is already enormous and will only increase, so it's hard to envision a scenario in which absolute levels of Netflix will decline," the report said. "However, Netflix is facing increased local competition, and as a result new services might grow at a faster rate."
