YouTube is the largest single source of mobile video traffic in every region worldwide with as much as 25% of network data and no less than 12%, according to figures posted on Multichannel.com based on a report from bandwidth-management equipment vendor Sandvine. In North America, YouTube accounts for 23.4% of daily traffic on mobile networks, followed by Pandora Radio at 6.4%. Netflix represents 2.1% of mobile data in North America. Real-time entertainment traffic will exceed 60% of mobile data in the U.S. by late 2014, Sandvine predicts.
The volume of Netflix‘s streaming-video traffic over wireline broadband networks in North America climbed 30% over the past six months, but Sandvine said Netflix’s share of overall usage has apparently leveled off at roughly 33% of all peak-hour downstream bandwidth. Netflix remains the largest single source of traffic on fixed-access networks and drives about a third of capacity infrastructure costs for cable and telco providers, according to Sandvine’s report. Overall, Netflix represents 24.4% of volume, ahead of BitTorrent’s 14.2%. Downstream during primetime, Netflix accounts for 32.9% of traffic, just slightly higher than the 32.7% Sandvine measured in September 2011. Sandvine concludes that “explosive growth seems to be over” for Netflix bandwidth consumption, and it predicts Netflix’s peak share to decline slightly to 32.5% as other video streaming services catch on. Sandvine predicts increased competition from YouTube (13.8% of peak downstream traffic), Hulu, HBO Go, Amazon Prime, and traditional TV networks streaming their content to game consoles and other devices.
