By 2019, 80 percent of all IP traffic will be video--a 13 percent increase from 2014, when video took up about 67 percent of IP-based traffic. That's the latest forecast from Cisco, which has released its 2015 Visual Networking Index. But mobile traffic won't be the biggest part of that figure. Advanced video services including 4K/Ultra-High Def, 360-degree/spherical video, and video-centric M2M applications will be among the biggest bandwidth hogs.
Not surprisingly, the United States and China will be the highest traffic-generating countries by 2019, at 45.7 exabytes and 21.9 exabytes per month, respectively. Internet video traffic specifically will climb to 105 exabytes per month worldwide, growing four-fold between 2014 and 2019, Cisco reports. More juicy number-crunching can be found here.
