Cisco: IP video
80% of traffic
ccording to the 10th annual
Cisco Visual Networking Index
(VNI) Forecast, annual Internet
Protocol (IP) traffic will triple between
2014 and 2019, when it will reach a
record 2 zettabytes. Factors expected to
drive traffic growth include
global increases in Internet
users, personal devices and
machine-to-machine (M2M)
connections, faster
broadband speeds, and the
adoption of advanced video
services.
Collectively, these variables
are expected to create a global IP
traffic compound annual growth
rate (CAGR) of 23% - the first
global CAGR increase in
consecutive VNI forecasts in
nearly a decade (e.g., last year’s
projected CAGR for 2013 - 2018 was 21%).
Cisco predicts that global IP traffic will
reach 168 exabytes per month by 2019, up
from 59.9 exabytes per month in 2014. In
2019, nearly as much traffic will traverse
global IP networks than all prior ‘Internet
years’ combined (from 1984 to the end of
2013).
Several elements will shape IP traffic in the
coming years:
A
l More Internet Users - As fixed and
mobile networks grow and expand, more
people will have network and Internet
access. In 2014, there were 2.8 billion
Internet users, or 39% of the world’s
population of 7.2 billion. By 2019, there
will be about 3.9 billion Internet users, or
51% of the world’s projected population of
7.6 billion.
Germany spectrum
auction under way
Germany’s
Bundesnetzagentur (Federal
Network Agency) has
admitted three companies to
its auction for spectrum for
mobile broadband:
Telefónica Germany; Telekom
Deutschland and Vodafone.
“Germany will be the first
country in Europe to make
spectrum in the 700
Megahertz frequency band

l Proliferation of Devices and
Connections - With 24 billion
networked
devices/connections expected
online by 2019, compared
with 14 billion in 2014, service
provider networks must adapt to an influx
of sophisticated devices.
l Faster Fixed Broadband Speeds Globally, the average fixed broadband
speed will increase two-fold from 20.3
Mbps in 2014 to 42.5 Mbps in 2019. From
a regional perspective, Western Europe
and Asia Pacific continue to lead the
world in fixed broadband network speeds.
l New and Advanced Video Services - IP
video will account for 80% of all IP traffic
by 2019, up from 67% in 2014.
Implications for Service Providers
l As a result of the increasing number of
devices that will need to be authenticated
to gain access to fixed/mobile networks,
increased bandwidth capacity is not the
only requirement in the next half decade.
l The evolution of advanced video
services and M2M applications are
expected to create new bandwidth and
scalability requirements for SPs.
Residential, business and mobile
consumers continue to have strong
available for mobile
broadband,” said Jochen
Homann, president of the
Bundesnetzagentur,
who said the Agency
expected the auction to
provide a strong impetus for a
rapid roll-out of the broadband
networks, especially in rural
areas.
In total, 270 MHz of
spectrum from the 700 MHz,
900 MHz, 1500 MHz and 1800
MHz bands are being
auctioned. The spectrum at
demand for advanced video services
across all network and device types
(quality, convenience, and price are key
factors for success).
l Continued business video adoption may
prompt greater growth in network
virtualisation and leveraging the Internet
for video transmission (network
ramifications for SPs/OTTPs).
l By 2019, more than 14% of monthly
global IP traffic will come from cellular
connections and 53% of monthly IP traffic
will come from Wi-Fi
connections. Differentiated and
monetisable mobile strategies
will be important for all SPs.
l IP networks must be
intelligent and flexible enough
to support the constant
introduction of new/updated
applications for fixed and
mobile networks. Many SPs are
actively collaborating with
application and content
