A new report by network gear manufacturer Sandvine unsurprisingly finds that video dominates Internet traffic, as file sharing networks share of overall traffic continues to fall. According to the company, mean usage on fixed line networks is now 44.7 GB per month, a 39 percent jump from the 32.1 GB per month recorded this time last year. Median bandwidth usage clocked in at 18.2 GB, up from 10.3 GB one year earlier. On wireless networks, mean usage was 390.1 MB, while median usage was 58.7 MB (clearly there's still a lot of feature phone users out there).

Some additional interesting bits from the study (which you can download here):

•20% of all traffic running over fixed networks in North America is running through smartphones or tablets running on home networks.

•Netflix unsurprisingly dominates fixed network traffic, consuming 32.3 percent of all traffic.

•Netflix consumed just 3.98% of peak mobile downstream traffic in North America, up from 2.2% one year earlier.

•Behind Netflix comes YouTube (17.11%), HTTP (11.11%), BitTorrent (5.57%), MPEG (2.58%), Hulu (2.41%), iTunes (1.9%) and SSL (1.89%).

•Apple products account for over 45% of all streaming audio and video on fixed networks.

•BitTorrent consumes the most upstream bandwidth, consuming 34.81% of all upstream traffic on fixed networks.

"We predict from this data that 2013 will be the year long-form video will make its move onto mobile networks," said Dave Caputo, CEO, Sandvine. "The "home roaming" phenomenon, the concept of subscribers voluntarily offloading mobile traffic onto Wi-Fi networks, has continued. This combined with increased consumption of real-time entertainment on mobile networks globally, and the doubling of Netflix traffic on mobile networks in North America, suggests that users are getting comfortable with watching longer form videos on their handheld devices."
