Cisco predicts that tablets, smartphones, etc will contribute more than half the IP traffic, up from today’s 33 percent. For the first time in the history of the internet, mobile and portable devices will generate more than half of global IP traffic by 2018. That’s one of the headline findings of Cisco’s latest Visual Networking Index (VNI), which forecasts global IP traffic for fixed and mobile connections between 2013 and 2018. Cisco finds 33 per cent of all IP traffic originated with non-PC devices in 2013. By 2018, however, that figure shoots up to 57 per cent.
