By region, Asia Pacific is expected to generate 40.5 exabytes of IP traffic a month by 2016 -- the most of all geographies. North America is expected to hit about 27.5 exabytes per month. The fastest growing IP traffic regions, however, are the Middle East and Africa, with a 58 percent CAGR, and Latin America, with a 49 percent CAGR.
By country, India will have the highest IP traffic growth rate from 2011 to 2016, Cisco said, with a CAGR of 62 percent. The United States and China will be the highest traffic-generating countries by 2016, at 22 exabytes per month and 12 exabytes per month, respectively.
Among other interesting data points in the VNI:
- There will be 8 billion IPv6-capable fixed and mobile devices by 2016, up from 1 billion in 2011.
- Advanced video traffic, which includes 3D and HD TVs, is expected to increase five times between 2011 and 2016.
- Business IP video conferencing will grow six fold from 2011 to 2016, growing more than twice as fast as overall business IP traffic.
- Mobile consumers are forecast to grow from 3.7 billion in 2011 to 4.5 billion in 2016.
- Consumer SMS will be the most highly-penetrated consumer mobile service, from 271 million users in 2011 to an expected 1.6 billion in 2016.
- Business mobile location based services will be the fastest-growing business mobile services, from 27 million users in 2011 to an expected 158 million in 2016.
The best way for solution providers to think about all these changes, Barnett said, is in terms of not only network upgrades to support all that IP traffic but also network intelligence.
"There can't just be a bigger pipe -- the network has to be more intelligent to build a better experience," he said. "Differentiation is going to be the key: How can service providers innovate on the network and how can they partner with others to do that?"
