Fascinating numbers out today in a report from Sandvine, a broadband monitoring company. The company’s first half of 2013 breakdown of internet consumption shows how real-time entertainment — aka streaming media — is responsible for the lion’s share of broadband traffic.

In other words, people are watching lots of Netflix and YouTube.

As can be seen by the chart above, fixed access (cable, DSL, fiber) broadband peak loads are being dominated by video streaming (and a little real-time communication like Skype), with 62 percent of aggregate up and downstream being eaten up by video and other streaming.

Just as interesting is how important the in-home wireless network is becoming to today’s broadband households. According to Sandvine, in the first half of 2012, 9 percent of traffic in the home network was delivered to mobile devices (smartphones and tablets), while in the same period in 2013 these devices accounted for 25 percent of in-home traffic.

The chart below shows the breakdown of real-time (streaming traffic) by device type. Mobile devices like tablets and smartphones account for a full 25 percent of streaming media delivered into the home over fixed broadband and then over a Wi-Fi network.

The chart also shows how each platform performs. While Windows machines still lead, iOS devices — tablets, Apple TVs and iPhones — account for nearly a quarter of traffic, and when adding in Macs, total Apple share of realtime traffic just beats (35.3 percent) that of Windows (35 percent), though if you add in Xbox, I have a feeling Microsoft’s total would well exceed that of Apple.
