Global IP Traffic is expected to reach more than half a zettabyte* in 2012, increasing by a factor of six from 2007 to 2012, according to Cisco, which said the growth would be driven by online video and Web 2.0 social-networking and collaboration applications.
Cisco‘s Visual Networking Index (VNI) also projects that total IP traffic will increase at a combined annual growth rate (CAGR) of 46% from 2007 to 2012, nearly doubling every two years. The result will be an annual bandwidth demand on the world’s IP networks of approximately 522 exabytes**.
Additional findings from the VNI, below:
In the consumer market, the advent of rich online video communications and entertainment, as well as social networking, has greatly increased the impact of online video on the network:
Global business IP traffic is forecast to grow strongly at a CAGR of 35% from 2007 to 2012:
“The broad and increasing adoption of visual networking is having a significant impact on IP traffic growth for both consumer and business services markets worldwide,” said Suraj Shetty, vice-president of service provider marketing for Cisco.
“Until just a few years ago, ‘exabyte’ was an unheard-of term. However, because of the massive growth we’re seeing, by 2012 we will have to reorient our vocabulary once again, as the metric that we need then will be the zettabyte.”
*A zettabyte is equal to 1 trillion gigabytes, 1,000 exabytes, 250 billion DVDs.
**An exabyte is equal to 1 billion gigabytes, 1,000 petabytes, 250 million DVDs.
About the research: The Cisco VNI Forecast and Methodology, 2007-2012 and the associated updated Cisco “Approaching the Zettabyte Era” whitepaper are part of the Cisco Visual Networking Index, an ongoing Cisco initiative designed to provide quantitative and qualitative information regarding trends in IP network demand and usage. The VNI highlights key findings on various consumer and business Internet Protocol (IP) networking trends. The combination of these technologies represents what is known as visual networking.
