Everyone is talking about the transition to IPv6 in the run up to the June 6th launch of the IPv6 Internet. Most of the discussion has focused on the technical details of various approaches – 6rd vs. DS-Lite vs. CGNAT for example. However, what we haven’t seen is an effort made to look at the economic impact of the choice between IPv4 extension vs. IPv6 transition and back it up with some real world data. A few months back we asked telecommunications analyst Nav Chander of IDC (pictured right) to evaluate and publish the results of an economic analysis of the IPv6 options. This is a crucial and timely topic because operators are faced with important decisions about which transition technologies to use, when to implement them, and where in the network.
We’re pleased to report that Nav is finished and is ready to reveal the results of his findings. To keep the scope of his analysis within a reasonable boundary, he initially focused on just one scenario: that of a wireline carrier considering the deployment of a Carrier Grade NAT-only implementation (which basically just extends the life of IPv4 with no IPv6), or migrating to IPv6 with a combination of CGNAT (for short term IPv4 extension) and while new customers were deployed with 6rd.
The results of this study are detailed in a new Read More »

For many students, this time of the year marks “Spring Break”. (Ah, just the thought of this brings back fun memories…) However, once you get past the stereotypical party imagery, it really is a time of assessment. Mid-term exams complete and we ask ourselves what we need to do to achieve that final grade. Service providers find themselves in similar circumstance with the IPv6 subject as World IPv6 “graduation” day quickly approaches in June.
At the March 20th Light Reading Cable event in Denver, two pioneers in the IPv6 field – our own Fred Baker, a Cisco Fellow and IETF Chair, and John Brzozowski, Chief IPv6 Architect at Comcast — talk candidly about the benefits of IPv6, beyond address widening; how operators are doing, in terms of the upcoming launch; and what happens post-transition. Fred also handles one he hears a lot “When is IPv6 going to be done? Because I’ll deploy it then…”

Cisco has taken a leadership role in driving the industry on the creation of standards associated with IPv6. At recent count we had over 458 RFCs related to IPv6 – over a third of the total!
One example of this is how our technical leaders have taken on the challenge in dual stack (IPv4 and IPv6) networks to reduce user-noticeable delays in when the IPv6 path is broken or slow. We’ve documented a method called “Happy Eyeballs” as described in Internet-Draft “Happy Eyeballs: Trending Towards Success (IPv6 and SCTP”).

How many devices do you have that are sucking up IP addresses? Apple continues to lure me in for the latest and greatest iPad and iPhones, with the new iPad being the latest to capture my eye. This continual proliferation of devices has been illustrated in the latest VNI results. Apple of course enables these devices with a fully functioning IPv6 stack as was demonstrated at the IPv6 World Congress this year. While at the IPv6 World Congress 2012 we had the opportunity to chat with Jacqueline Queiroz , a Network Architect with Orange, about IPv6 adoption.
Network operators, content providers and device manufacturers all are navigating the IPv6 migration waters – Orange is no different. IPv6 adoption progress varies, but France has been proven to be one of the global leaders in IPv6 adoption. This was well chronicled in a study conducted by Google and discussed further here. Orange being headquartered in France plays an obvious role in this adoption trend. Read More »

Unless you have been asleep behind the wheel of your network, you know the IPv6 Internet will go live on June 6th, 2012 and Cisco is taking a leading role. If you didn’t make it to Paris a few weeks back for v6 World Congress there are two upcoming events in Denver, Colorado where you can learn about deploying IPv6 in your network.
1. Breakfast Session: Making the IPv6 Transition will be held the morning of Tuesday March 20th from 7:30-930 am before the Lightreading Cable Next-Gen Broadband Strategies: Wideband, Wireless, PON & Beyond event. Fred Baker, Cisco Fellow and current Co-chair of the IETF IPv6 Operations Working Group, will be presenting and taking questions at the breakfast. He’ll cover how cable operators can deploy IPv6 on their network and will be available to meet with attendees after the breakfast. Register here to take advantage of this special opportunity.
