By 2013, annual global IP traffic--driven principally by video--will grow more than 500 percent from current levels, Cisco now estimates. ideo. In 2013, the Internet will be nearly four times larger than it is in 2009. By year-end 2013, the equivalent of 10 billion DVDs will cross the Internet each month.
Cisco forecasts that 90 percent of consumer IP traffic, a majority of total IP traffic, will be video in 2013.
In 2013, Internet video will be nearly 700 times the U.S. Internet backbone in 2000.
Also, video communications traffic growth is accelerating. Though still a small fraction of overall Internet traffic, video over instant messaging and video calling are experiencing high growth. As a result, video communications traffic will increase tenfold from 2008 to 2013, Cisco says.
Real-time video is growing in importance. By 2013, Internet TV will be over four percent of consumer Internet traffic, and ambient video will be eight percent of consumer Internet traffic.
Live TV also has gained substantial ground in the past few years. Globally, P2P TV is now slightly over seven percent of overall P2P traffic at over 200 petabytes per month.
Video-on-demand traffic will double every two years through 2013, with consumer IPTV and CATV traffic growing at a 53 percent CAGR between 2008 and 2013, compared to a CAGR of 40 percent for consumer Internet traffic.
Cisco also predicts that mobile data traffic will also be overtaken by video, reaching 64 percent of total mobile IP traffic by 2013.
Cisco expects mobile video to grow from 33 petabytes a month in 2008 to 2,184 petabytes (or 2 exabytes) a month in 2013, which represents a 131 percent compound annual growth rate.
Peer-to-peer is growing in volume, but declining as a percentage of overall IP traffic, Cisco says. P2P file-sharing networks are now carrying 3.3 exabytes per month and will continue to grow at a moderate pace with a compound average growth rate of 18 percent from 2008 to 2013.
Other means of file sharing, such as one-click file hosting, will grow rapidly at a CAGR of 58 percent and will reach 3.2 exabytes per month in 2013.
Despite this growth, P2P as a percentage of consumer Internet traffic will drop to 20 percent of consumer Internet traffic by 2013, down from 50 percent at the end of 2008.
