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 »

We’ve all now returned from the stardust of the annual National Association of Broadcasters convention in Las Vegas last week, which seems a useful time to reflect briefly on the major threads of the show. It was a great one for us, and I’m pleased and grateful to report the following, in no particular order:
1. Broadcasters and program networks are getting fired up about the IP transition, like the rest of us, and not a moment too soon. We fielded tons of questions about the cost savings associated with CDNs (Content Delivery Networks), IP distribution over terrestrial fiber networks–the proliferation of IP-based, video-capable screens, and cloud–how to get new services to market more quickly and how to streamline workflows. Transcoding engines, contribution networks, and all of the tacit and explicit benefits of the overall IP migration were all hot topics.
Of course, we, as Cisco people, can talk about IP all day long. And so we did: One of the Cisco booth demos highlighted Read More »

The 2012 North American IPv6 Summit was held in Denver, Colorado on April 9-12, 2012. As usual, it was an excellent conference with the largest attendance of any IPv6 event in North America this year. There were many excellent speakers who gave timely talks on the state of IPv6 deployment, gaps in the overall education within the end-user base as well as advances and limitations in vendor support.
I gave a keynote talk on “Enterprise Internet Edge Design for IPv6” and afterwards I was approached by several enterprise customers who stated that they had great success using the Cisco Validated Design (CVD) options defined in our Deploying IPv6 in the Internet Edge CVD. This is great to hear but our work is not done yet. We still need to help customers understand the significance of deploying IPv6 in not just the network but throughout the enterprise. This is most evident in the lack of documentation by commercial off the shelf (COTS) application vendors who need to do a better job of helping customers understand the support for IPv6.

When we last tuned in we discussed how the IPv6 certification process is designed to ensure devices properly implement the IPv6 protocol and interoperate with all other certified components. It was also mentioned that, with the level of revenue generated by today’s public network, the owners of these networks are hesitant to fully implement the protocol with fears of instability. The world’s governments are leading the efforts in proving this network stability by designing their next generation networks around the IPv6 protocol.

Last week the UN’s Broadband Commission held its fifth meeting to discuss how to extend the broadband Internet to the almost six billion people on the planet who have yet to connect at broadband speeds. A critical component to extending the Internet is the work done by the multi-stakeholder technical community, especially the Internet Engineering Task Force (IETF).
From March 25th through the 30th, the IETF held its 83rd meeting and Cisco was honored to be the host sponsor. Over fourteen hundred attendees, from 56 countries, participated in the meeting which gathered a large open multi-stakeholder community of network designers, engineers, operators, vendors, and researchers concerned with the evolution and smooth operation of the Internet. Technologies previously defined by the IETF, such as IPv6 and DNSSEC, are now at the forefront of efforts to ensure the Internet’s continued growth as a trusted platform of communications and innovation for billions of people around the world. As a result, the Internet has now grown to be essential to the 21st century global economy and a key driver of social development due in large part to the work of the IETF.
As the IETF nears its 30th year, challenges still remain Read More »
