It’s that time of year: take a break, reflect, maybe clean up the hard drive.
I had a chance to do the reflection part last week, and came up with what I hope is a pretty good weave of what Service Providers experienced over the last 12 months.
Here is my ‘take’ on the top five trends of the whirlwind year that is still, for a week or two, 2011:
1. In the crawl-walk-run sequence as it relates to the global shift to all-IP, 2011 went from “crawl” to “jog” — skipping “walk” entirely.
Think about it. Think about all of it, which is a lot, when it comes to the global transition to all-IP: Fixed networks; mobile Internet, Video, Cloud.
Across the world, wherever there is IP, there was monumental change in 2011. While 2010 was a year of anticipation and preparation, 2011 teemed with news and trends about the burgeoning Internet: more Video, more emphasis on mobile broadband; more work on keeping the “big iron” routing and switching fabrics around the world plumbed to keep up with demand.
We continued to do our best to keep up with the enormity of all-IP, with our ongoing VNI (Visual Networking Index) and Cloud Index forecasts. We’re still anticipating a quadrupling of Internet traffic by 2015, mostly because of video usage by mobile and “connected” IP devices. Lots more data here.
2. Video (still) trumps as the biggest driver in Internet / IP usage. Read More »

With the emergence of cloud computing, our customers have looked for real-world data that could help them understand the nature and scope of the cloud phenomenon. But that kind of data has not been readily available.
Not satisfied with this lack of information, a research team at Cisco reviewed 30Tb of data each month, more than 45 million speed tests, analyst forecasts, and inputs from our customers. The result?
Today, Cisco released its first Cisco Global Cloud Index report — a forecast of IP data center and cloud-based traffic growth and trends worldwide, 2010-2015.
Similar to the Cisco Visual Networking Index in purpose and approach, the Global Cloud Index enables organizations to make strategic networking and management decisions and governments to make informed public policy decisions.
Some highlights from the report reveal: (all data global)
1. Cloud traffic is growing twice as fast as data center traffic, increasing from 130 exabytes in 2010 to 1.6 zettabytes annually by 2015
- 1.6 zettabytes is approximately equivalent to 22 trillion hours of streaming music
- 76% of this traffic will remain within the data center itself
- By 2015, 57% of all data workloads will be processed in the cloud Read More »

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?
