In a survey of more than 20 top service providers, Cisco Systems finds that video and other visual applications now constitute 30 percent of traffic running through service provider networks, feeding into Cisco's assertion that such visual apps will dominate networks by 2013. In addition, the top 1 percent of broadband subscribers worldwide generate 10 percent of the traffic.
Video and other visual applications continue to drive the traffic crossing
service provider networks, according to a study by Cisco Systems.
In results stemming from Cisco's VNI (Visual Networking Index) Usage study
released Oct. 21, Cisco officials said more than a third of the average global
broadband connection supports video, social networking and collaboration
applications every month.
The information comes from more than 20 service providers worldwide, and
feeds into what Cisco officials say they are seeing in the industry, in
particular that the growth
in visual traffic
across networks will be rapid and dramatic.
In June, Cisco said Internet traffic worldwide would grow to five times its
current size between 2008 and 2013, due in large part to the rise in video
traffic. The company estimated that by 2013, 90 percent of all consumer IP
traffic would be video.
The findings released Oct. 21 represent a snapshot of what's going on now-at
least, in the third quarter of 2009-while the full VNI study looks ahead five
Among the findings were that worldwide, the average broadband
connection-mostly residential subscribers, though some business users were
mixed in-generates about 11.4GB of Internet traffic per month, which roughly
translates to downloading 3,000 text e-mails, 100 MP3 music files or 360
text-only e-books per day.
Every month, the average broadband connection consumes about 4.3GB via
visual networking applications per month-everything from video to social
networking to collaboration.
In a video talking about the findings, Doug Webster, senior director of
market management at Cisco's Service Provider Group, said the traffic generated
by such applications is rising, while traffic generated by peer-to-peer
applications is dropping.
"Its percentage [now at 38 percent] is going down because so many of
the other services, such as visual networking services that are video-based
[and] communications-based, are really growing at a much faster rate,"
Other results from the survey include that the top 1 percent of global
subscribers are generating more than 20 percent of all the traffic, and the top
10 percent of global subscribers generate more than 60 percent of the traffic.
In addition, the prime time for Internet use is from 9 p.m. to 1 a.m.,
and 25 percent-about 93.3MB per day per connection-is generated during this
time. A peak Internet hour has 20 percent more traffic than a nonpeak Internet
hour, according to Cisco.
