World's internet traffic to surpass one zettabyte in 2016
The growth in traffic will put more strain on networks James Titcomb

Global internet traffic will pass one zettabyte for the first time this year, after increasing fivefold in the last five years.
, the networking company that supplies much of the world’s internet infrastructure, says that the total amount of traffic will reach around 1,060 exabytes, or just over one zettabyte.
That’s a lot: one billion terabytes, or one trillion gigabytes or 1,000,000,000,000,000,000,000000 bytes. Or 667 trillion films, or 152 million years of high-definition video (based on a two-hour, 1.5GB film).
Cisco is predicting that internet traffic will double again by 2019, with much of the growth driven by huge increases in mobile data use. Mobile data will grow at an average rate of 57 per cent a year, although most internet traffic will continue to be made up of fixed broadband.
Much of the increase in network traffic, which will place a burden on infrastructure and is likely to require heavy investment, will come from online video.
Data-thirsty video streaming will make up 41 per cent of all internet data this year, rising to 54 per cent in 2019. By then, Cisco says, less than half of all internet traffic will have come from PCs, as connected TV devices, smartphones and tablets account for more data.
The strain on the network is likely to be felt at busy hours - even more so than now. Traffic during the busiest hour of the day will increase 3.4 times between 2014 and 2019, compared to 2.8 times for average traffic.==============================================
