With the onset of cloud, we’re being asked more and more by our customers about the architectural requirements that result from it. While the customers have an instinct as to what’s needed, there seems to be less actual data to that effect than what they would like. When confronted with a similar situation over 5 years ago about the network, we developed the Cisco Visual Networking Index which focuses on the amount of traffic carried across the network to the end user to help gauge the extent of infrastructure needed to support the data deluge. Now with the network becoming inextricably linked to the data center and cloud, we realized we need to look at the other half of the equation as well to get a truly comprehensive architectural view. To achieve this, we reviewed 30Tb of data each month, more than 45 million speed tests, analyst forecasts, and inputs from our customers. The result? The inaugural Cisco Global Cloud Index, released today.
Here are a few takeaways to consider:
- Global data center traffic is estimated to grow four-fold to reaching a total of 4.8 zettabytes annually by 2015.
- The vast majority of the traffic – 76% — surprisingly, doesn’t even hit the network but instead stays within the data center itself, as workloads are constantly being migrated to different virtual servers.
- Of the total data center traffic, about 11%, or 130 exabytes of annual data center traffic in 2010 is considered part of the cloud – however that amount is going to grow significantly in the next half decade, reaching more than a third of data center traffic, or 1.6 zettabytes annually, by 2015.
Cloud may be the concept-of-the-day for the industry, but with growth like that, it shouldn’t be discounted as a passing fad but rather a lasting trend whose impact will fundamentally affect network architectures going forward. Read More »

According to Cisco’s Visual Networking Index, network operators will deliver upwards of a zettabyte (1021 bytes) of data to 15 billion fixed and mobile devices by 2015. That will be the challenge of the Next-Generation Internet.
To meet that challenge, service providers will need networks that meet the following requirements:
- Support for mobile, business and residential services over a converged infrastructure
- Unprecedented scale and density
- High service availability
- Increased service velocity
- Reduced network complexity Read More »

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 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 »
