In its annual Visual Networking Index, Cisco Systems said Internet traffic worldwide will quadruple by 2014, driven by the rapid growth in video traffic generated by both consumers and businesses. Video will constitute more than 91 percent of all consumer IP traffic, and this year will overtake peer-to-peer traffic as the top traffic generator.
Cisco Systems is predicting that global Internet traffic will more than
quadruple by 2014, driven in large part by increases in video traffic and by
people using the Web to communicate online.
In its annual Visual Networking Index released June 2, Cisco said
Internet traffic will grow to 767 exabytes by 2014. The growth will be rapid,
the company said, noting that traffic between 2013 and 2014 will jump 100
exabytes-about 10 times all the traffic running through IP networks in 2008.
By 2014, the monthly IP traffic will reach 63.9 exabytes, which
according to Cisco is equal to 16 billion DVDs, 21 trillion MP3s or 399
quadrillion text messages.
Fueling the growth will be video, Cisco said. All forms of
video-including TV, video-on-demand, Internet video and peer-to-peer video-will
be more than 91 percent of consumer traffic worldwide. In addition, by the end
of this year, global Internet video traffic will surpass peer-to-peer traffic,
the company said. There will be more than 1 billion online video users by the
end of 2010.
This year also will be the first time in 10 years that
peer-to-peer traffic-consumers directly sharing files online-is not the top
type of Internet traffic.
To illustrate the amount of video that will be crossing
networks in 2014, Cisco said that to watch all the video crossing networks that
year would take 72 million years.
All of this will put tremendous pressure on service providers,
according to Pankaj Patel, senior vice president and general manager of Cisco's
Service Provider Group.
"Service providers are faced with evolving bandwidth and
scalability requirements as residential, business and mobile consumers continue
to demonstrate a healthy appetite for advanced video services across a variety
of networks and devices," Patel said in a statement. "IP networks must be
intelligent and flexible enough to support this tremendous variety of traffic
Cisco not only is the top vendor of switches and routers that
move traffic through the networks, but also is betting heavily on video in
other parts of its business.
The company has become a top video conferencing player,
particularly since its $3.4 billion acquisition of telepresence
. Cisco sees businesses looking to save money in such areas
as travel, and are looking to video collaboration technologies as ways of
improving productivity while keeping costs down.
Cisco believes the worldwide telepresence market could grow
from $3 billion this year to more than $10 billion over the next few years.
In addition, Cisco is looking to bring high-definition video
communications into the home, and currently is
testing a consumer TelePresence offering
that could hit the market later
this year. The move would let it compete with the likes of Skype.
