Santa Clara, CA - Jun 1, 2011 - Cisco Systems, as part of its ongoing Visual Networking Index, is predicting that global Internet traffic will quadruple over the next four years.
The executive summary of the latest report can be found at this link. Some highlights: Global IP traffic, which has increased eight-fold over the last five years, will increase four-fold over the next five years. The compound annual growth rate (CAGR) will be 32 percent from 2010 to 2015.
A growing amount of Internet traffic is originated by non-PC type devices. In 2010, only 3 percent of Internet traffic came from such sources, but Cisco expects the CAGR to grow to 15 percent of Internet traffic by 2015. PC-originated traffic will also grow, along with that of TVs, tablets, smartphones, and machine-to-machine traffic. Cisco estimates those growth rates at 101 percent, 216 percent, 144 percent and 258 percent respectively.
Traffic from wireless devices will exceed that of wired devices by 2015.
By 2015, the gigabyte-equivalent of all the movies ever made will transit global IP networks every five minutes. More specifically, this works out to 7.3 petabytes (7.65 million gigabytes) every five minutes.
