Video to account for nearly 90% of consumer IP traffic by 2012, projects Cisco
June 17, 2008 - Video on demand, IPTV, peer-to-peer (P2P) video and Internet video will account for nearly 90% of all consumer IP traffic worldwide by 2012, according to new projections by Cisco, and Internet video alone is expected to account for 50%, compared to the current 22%.
The research also predicts that IP traffic will increase at a combined annual growth rate (CAGR) of 46% from 2007 to 2012, nearly doubling each year, resulting in an annual demand on the world's IP networks of approximately 522 exabytes (522,000,000,000,000,000,000 bytes), or over half a zettabyte. The findings also project that Web-based video will overtake file sharing as a percentage of Internet traffic within two years.
"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."
One exabyte is equivalent to 1bn gigabytes or roughly 250mn DVDs.
