The amount of Internet traffic will quadruple over the next four years. That’s the prediction contained in Cisco Systems’ (Nasdaq: CSCO) annual Visual Networking Index Forecast, the company’s ongoing initiative to forecast and analyze Internet Protocol (IP) networking growth and trends worldwide.
The index predicts annual global IP traffic to be 1.3 zettabytes by 2016. Zettabytes are equal to a sextillion bytes. The projected increase of global IP traffic between 2015 and 2016 alone is almost equal to the total amount of global IP traffic generated in 2011.
Cisco analysts say the increase in devices such as tablets and mobile phones, as well as faster broadband speed and more video will contribute to the growth. By 2016, more than half of the world’s Internet traffic is expected to come from Wi-Fi connections, and broadband speed will be about four times faster than it is today.
