Cisco Visual Networking Index Forecast 2009-2014 (VNI)

The Cisco Visual Networking Index (VNI) Forecast, 2009-2014, projects that global Internet traffic will increase more than fourfold to 767 exabytes — or more than 3/4 of a Zettabyte, by 2014. This amount is 100 exabytes higher than the projected level in 2013 — or an increase the equivalent of 10 times all the traffic traversing Internet Protocol networks in 2008. The growth in traffic will continue to be dominated by video, exceeding 91 percent of global consumer IP traffic by 2014. Improvements in network bandwidth capacity and Internet speeds, along with the increasing popularity of HDTV and 3DTV are key factors expecting to quadruple IP traffic from 2009 to 2014. The Cisco VNI Forecast, which focuses on two primary user groups — consumers and businesses — was developed as an annual study to estimate global IP traffic growth and trends. Projections are based on Cisco analysis and modeling of traffic, usage, and device data from independent analyst sources. Cisco validates its forecast, inputs, and methodology with data provided by service providers worldwide. more info at: www.cisco.com
