Web traffic will quadruple to one zettabyte a year by 2015, according to Cisco's researchers.
As part of its annual report on the state of the web and networking, Cisco trotted out some mind-numbingly large numbers, including the prediction that global traffic will hit the equivalent of a trillion gigabytes in four years.
That traffic jump will be caused by more web users - up to three billion by 2015 - and more devices hooking up to the web, with Cisco predicting 15bn devices will be connected.
Increasingly, those connections won't be PCs. As of 2010, 97% of web connections by consumers was via computers, but by 2015 that will fall to 87% as more people use tablets, smartphones, and web TVs to get online.
Cisco also believes the average global broadband speed will jump from 7Mbits/sec in 2010 to 28Mbits/sec in 2015, after doubling over the past year from 3.5Mbits/sec to 7Mbits/sec.
