By Steven Shepard, Contributing Columnist

If you read my prior story on this topic, and appreciate my love of conversations with cab drivers, then you’ll understand this cryptic note:

Digital Britain: BIG things are happening

August 4, 2011 at 2:00 am PST

My wife was shopping online this past week. While she was watching the rich-media cat walk feature on asos.com, which is now the norm for clothing retailer websites, it occurred to me how things have changed. Moreover, how our expectations have dramatically evolved.

On a regular basis I hear friends, colleagues and business partners complain about the perceived speed of their internet connection – web pages not loading fast enough, unable to reach a particular website, or a poor user experience on Skype. Consumers are demanding more – more broadband speed, better applications and abundant availability.

Cisco.com users on World IPv6 Day 5 to 10 times more likely to use IPv6 than visitors to other websites

While looking over our data from World IPv6 Day, we found that 2.26% of all users who logged in with a username and password to www.cisco.com on June 8 did so over IPv6. That is nearly an order of magnitude greater than between the less than .2% and .3% averages reported by sites operated by more broadly visited websites such as Yahoo, Facebook, and Google. In contrast to those who logged in with their username and password, the total proportion of unique users who visited our site via IPv6 was estimated at just under 1.5%, which still represents at least a five times greater likelihood that a given cisco.com visitor reached us via IPv6 vs. the broader population of Internet users.

This shouldn’t be surprising at all. The cisco.com user base is made up of networking and IT professionals that are likely more willing to go out of their way to obtain IPv6 connectivity than most users. We hope that you will continue to use IPv6, show others how, and that we’ll have even more IPv6 users the next time we make www.cisco.com AAAA records available (see Fred Baker’s blog on what might be next).

In terms of overall traffic, our netflow statistics reported that 1.11% of traffic to and from www.cisco.com was served over IPv6. This traffic was delivered via an IPv6 to IPv4 load-balancing proxy function within our Application Control Engine (ACE) 30, allowing us to keep our existing production www.cisco.com virtually untouched while still providing an IPv6 web presence. On June 8, we used a pre-release version of code, alongside other Early Field Trial (EFT) customers. Matthew Laslie, Network Engineer and Architect at Savvis writes:

“Savvis was looking to provide IPv6 reachability to our primary websites without performing major modifications to our backend application/security infrastructure.  After evaluating several solutions, Savvis selected the Cisco ACE.  In the span of two short days the ACE was fully installed, configured and providing IPv6 reachability for several Savvis corporate websites.”

In addition to the participants that officially signed up for World IPv6 Day, others moved ahead on June 8 without the formalities. Cisco EU IPv6 Deployment Council member and customer Strato let us know after World IPv6 Day that they are now announcing IPv6 AAAA records for over four million domain names. Wilhelm Boeddinghaus, Head of Networks at Strato writes:

“Our customers don’t ask us for IPv6, nor do they ask us for IPv4, they ask us for the Internet, and that’s what we give them. Today the Internet is more than IPv4. The working Internet provides both protocols.”

Those four million domain names represent the ability of the content side of the IPv6 Internet to move very rapidly to IPv6. The fact that they decided to leave IPv6 on after June 8 is testimony to the confidence they have in IPv6, and that it is the right thing for their customers. There were a number of other websites that opted to keep their AAAA IPv6 records active after the 24 hour test on June 8, including our own www.scansafe.com, which moved to IPv6 by announcing AAAA records on World IPv6 Day and continues to today.

Given the relatively high turnout of IPv6-enabled www.cisco.com users vs. the rest of the industry, we have yet another clear data point of the importance of IPv6 to our customers. With all the success around World IPv6 Day, it seems hard to fathom that this will be the only event of its kind and we are eagerly looking forward to participating in and helping our customers with the next “World IPv6″ event. Stay tuned…

The Internet of Things [INFOGRAPHIC]

When we think of being connected to the Internet, our minds immediately shift to our computers, phones, and most recently tablets. This week at Cisco live, I shared that in 2008, the number of devices connected to the Internet exceeded the number of people on Earth.

That’s right. There are more devices tapping into the Internet than people on Earth to use them. How is this possible?

From QoS to QoE: A Fundamental Change in Focus

By Steven Shepard, Contributing Columnist

I’ve been thinking a lot lately about evolution. Not the Darwinian type, nor even the evolution of business (such a common theme today among business strategists), but rather about the evolution of the market — and most specifically about the changing demands of the market as its choices become richer and more varied in the face of remarkable technological change.

Since 1876, when Alexander Graham Bell spilled a beaker of hydrochloric acid into his lap, causing him to call out to his colleague, “Come here Watson, I need you,” thus starting the communications revolution that would change the world (Watson unexpectedly heard Bell’s voice through the speaker on the device they had invented), telephone companies have prided themselves on the quality of the service they have offered to their customers.
