What consumption trends are changing
the network?
• Mobility
Mobility
• Global mobile data traffic grew 70 percent in
2012
• In 2012, a fourth-generation (4G) connection
generated 19 times more traffic on average than
a non-4G connection
• Last year's mobile data traffic was nearly twelve
times the size of the entire global Internet in
2000

• Mobility
• Video
Video
• Globally, consumer Internet video traffic will be
69 percent of all consumer Internet traffic in
2017, up from 57 percent in 2012
• Content Delivery Networks (CDNs) will carry
over half of Internet traffic in 2017
• It would take an individual over 5 million years
to watch the amount of video that will cross
global IP networks each month in 2017

• Cloud
Cloud
• By 2016, nearly two-thirds of all workloads will
be processed in the cloud
• Global data center IP traffic will nearly
quadruple over the next 5 years
• Traffic crossing the Internet and IP WAN
networks is projected to reach 1.3 zettabytes per
year in 2016

How does the network of the future
respond?
How does the network of the future
respond?
• Capacity
Future Network - Capacity
▫ Wireless
 3G to LTE to LTE advanced
 802.11g to ‘n’ to ‘ac’
 New spectrum
▫ Wireline
 100 Gbps Ethernet
 Increasingly narrow wavelength channel width’s
(12.5Ghz)
 8 Tbps today on the backbone, next iteration is 32
Tbps then 80 Tbps.
How does the network of the future
respond?
• Capacity
• Efficiency
Future Network - Efficiency
• Converged Network all using IP & Ethernet
• Remove legacy transport technologies
▫ SONET, Frame Relay, ATM
• Further integration of routing and switching
• Further integration of optical and routing
How does the network of the future
respond?
• Capacity
• Efficiency
• Scale & Transparency
Future Network – Scale & Transparency
• Further network management abstractions to
simplify and scale network operations
▫ Out with CLI
▫ Service based monitoring and provisioning
▫ Software Defined Networking (SDN)
• Increased network control and visibility from
users
▫ Granular application level visibility
▫ User, usage and time based provisioning
