IP Traffic in 2017: 1.4 Zettabytes

Cisco predicts massive growth in global Internet usage

Based on observations made at ISPs around the world, Cisco forecasts that by 2017, annual global Internet traffic will rise to 1.4 zettabytes (that’s 1021 bytes), compared to “just” 528 exabytes (1018 bytes) in 2012. At this time 80 to 90 percent of all consumer Internet traffic will be some form of video, but other sources contributing to the rise include machine-to-machine communication and the proliferation of mobile devices.
