The Era of Zettabytes Has Arrived Says Cisco
Global internet traffic will reach 1.6 zettabytes by 2018 according to Cisco. What?! You’ve never heard of a zettabyte? We havent either, but according to Cisco one zettabyte equals a trillion gigabytes. So, even if we can’t get our heads around exactly how big a zettabyte is, we do know that it means a lot of people watching a lot of video on a lot of devices. Cisco estimates in it’s Video Network Index for 2014 that almost 80% of all IP traffic will be video. It’s not an unreasonable estimate given that 65% of internet traffic was video last year.
Here are two charts that GigaOm put together using the Cisco data:
Another useful data point that GigaOm highlights is the number of non-PC devices driving online traffic. By 2018 Cisco predicts that 57% of global IP traffic will come from non-PC devices. Again, look at the GigaOm breakout:
There’s lots more to delve into, including average traffic per user, and per household, and dozens of breakouts. Here’s the link to Cisco’s Visual Networking Index data for 2014.
