In the fifth annual Cisco Visual Networking Index (VNI) Forecast (2010-2015) released earlier this week, we indicated that the total amount of global Internet traffic is expected to quadruple by 2015, reaching 966 exabytes per year. This growth is driven by four primary factors: an increasing number of devices; more Internet users; faster broadband speed; and more video. In addition, the study forecasts that by 2015, the Asia Pacific region will generate the most IP traffic (24.1 exabytes per month), supplanting North America (22.3 exabytes per month) for the top spot. Such a shift is indicative of not only the region’s growing economies but also of the increased broadband penetration in the region, permitting more and more of the large Asia Pacific populations to get online and become both consumers and generators of IP traffic.
One of the useful elements of the VNI, highlighted in my earlier post, is the ability to easily analyze the data to generate specific, customized views of trends as it pertains to various regions, countries, and service types . Using the VNI Forecast Widget (see the link above), I was easily able to take a closer look at traffic forecasts in China and generate the graph below. This shows that by 2015, Internet traffic in China is estimated to be six times what it is in 2010 – a rate that is significantly faster than the global average (figure below is in Exabytes per month). How will enough network capacity to handle all of these IP packets be provided?

One of the more nuanced aspects of hard-core technological developments in the cable industry these recent months is the “CMAP v. CESAR” debate. Haven’t heard of it? Boiled way down, it’s a different set of viewpoints about the best way to migrate to a converged CMTS and universal edge QAM architecture, in conjunction with cable’s HFC (hybrid fiber-coax) plant migration.
To put this in historical context, cable operators “went digital” in phases. Digital video was first, followed by broadband data via cable modems, followed fairly shortly after by voice over IP. Operators use a form of modulation called “QAM” (quadrature amplitude modulation) to get video, data and voice signals over the plant to subscribing homes and businesses.
At issue was simple market timing: Digital video vendors built QAM products specifically to support video; broadband-side vendors built different QAM products, for high-speed data; and voice equipment vendors built QAM based TDM products for voice. The proprietary data and voice products where later replaced with the standardized DOCSIS CMTS platform. Read More »

One of the busiest times of the year for my team comes every June when we release the Cisco Visual Networking Index which forecasts IP Traffic growth around the globe. Now in its 5th year, the forecast, which initially started as a internal project to guide our own engineers as they innovate the next generation of networking infrastructure, has now grown to be an innovation in its own right, helping to provide data for our service provider customer and regulatory bodies alike (not to mention press, analysts, and IP groupies like yours truly.)
The top level finding of this Cisco VNI Forecast, which spans from 2010 to 2015 is that total worldwide IP traffic will increase 4x by 2015, reaching 966 exabytes or just under 1 Zettabye (which is 10 to the 21st power) To put context to rising demand of IP over the last several years, we have had to change the unit of measurement several times just to keep up with the growth…. First it we measured traffic in terms of Petabytes… then moved to Exabytes… and now are embarking on Zettabytes…(looking ahead, we’ll eventually start to use the term Yottabyte…)
Factors that are driving this growth, include:
- Video, as it is increasingly a part of nearly every networked experience. By 2015, one million minutes of video – nearly two years worth – will cross the network every second.
- More devices are connecting to the network – we forecast more than 15 billion will be on the network by 2015, making it on average more than two devices (whether it be a PC, phone, TV, or even machine-to-machine) per person for every person on earth (and if you’re like me, you’re an “overachiever” on this number, with well over a dozen devices connected to the network…by the way, just how many network connections are you responsible for?)

Just how rapidly is Internet usage growing? Consider this:
- Total global Internet traffic will quadruple by 2015, reaching 966 exabytes per year, nearly a zettabyte.
- By 2015, the traffic equivalent of all the movies ever made will cross the Internet every 5 minutes.
- In 2015, one million minutes of video content will cross the global network every second.
These “wow!”-inspiring data bits come to you courtesy of the just-released “Cisco Visual Networking Index Forecast, 2010-2015.”
We are indeed on the threshold of the “Zettabyte Era.” And the implications are significant: Read More »

It’s been an exciting two years since we introduced the Cisco Unified Computing System (UCS) solution to the world. UCS provides virtualized compute and networking with simple management. I want to congratulate our service provider customers on their successes in delivering differentiated services, with UCS as the foundation, in their markets. I would also like to extend our thanks to our business partners, both channel partners and those with complementary product offerings, for their expertise and ability to help accelerate this truly innovative idea across the data center and cloud industry.
In two short years, Cisco has risen to the #3 player in the fastest growing segment of the x86 server market.
Released yesterday, the IDC press release on Worldwide Quarterly Server Tracker Q1 2011 highlights the UCS uptake by our customers and partners and shows a great start to our vision for UCS in every SP, enterprise, and public sector organization looking for a world-class scalable, flexible, and powerful converged server platform. The rapid growth from launch to #3 in the industry for x86 blade servers in such a short time indicates two points: First, that the data center industry was crying out for real technology innovation and, second, that innovative customers are willing to embrace a new paradigm when the business benefits delivered are compelling.
