Globally, IP video will represent 80 percent of all traffic by 2019, up from 67 percent in 2014, according to Cisco. That necessarily drives other trends.
For the first time, more than 50 percent of the data traversing both Transatlantic and Transpacific submarine networks will be driven by content providers, not traditional telcos.
Likewise, 50 percent of the volume of content consumed over the internet, globally, is served by content delivery networks, and is growing.
And since much of the total video is driven by a relatively small number of content providers, operating huge data centers, it also follows that global undersea traffic ultimately originates in a relatively small number of global content store locations.
At the same time, “cloud computing” magnifies the trend, as a growing percentage of total computing activities occur at cloud data centers.
The point is that global traffic is driven by content.
