The number of internet connected devices is set to explode in the next four years to over 15 billion - twice the world's population by 2015.
Technology giant Cisco predicts the proliferation of tablets, mobile phones, connected appliances and other smart machines will drive this growth.
The company said consumer video will continue to dominate internet traffic.
It predicts that by 2015, one million minutes of video will be watched online every second.
The predictions come from Cisco's fifth annual forecast of upcoming trends.
Cisco's Visual Networking Index also estimated that at the same time more than 40% of the world's projected population will be online, a total of nearly three billion people.
The networking giant forecast that by 2015 internet traffic will reach 966 exabytes a year.
An exabyte is equal to one quintillion bytes. In 2004, global monthly internet traffic passed one exabyte for the first time.
But Cisco said alongside this quadrupling of traffic comes a number of very real concerns.
"What you are seeing is this massive growth in devices, the way devices are being used and are connected to the internet and what users expect them to do," said Suraj Shetty, Cisco vice president for global marketing.
"All this is putting a lot of pressure on the internet and the next generation internet faces issues handling not just the proliferation of these devices but how they are going to grow and be intelligent enough to be connected to you.
"The most important question we face is how to manage all this traffic intelligently," Mr Shetty added.
