One of the topics we covered this week at the Cisco Packet Optical Networking Conference was cloud computing. A benefit of cloud computing is that the physical infrastructure – the storage and compute resources – can be located almost anywhere as long as there is reliable network access. Several countries are leveraging their low cost green power to grow their economies with new data center facilities. A publicly announced example of this is Facebook which has built an enormous facility in northern Sweden. Iceland with its cooler temperatures and green geothermal power, plus ideal location between North America and Europe has seen a significant growth in its data center industry. However, being an island nation it faces a challenge to ensure that sufficient cost-effective network capacity is available to connect off-island users with its storage and compute resources.
When I was younger and faced with a large problem, I tended to shy away from the problem and take other paths to avoid the issue in the hope that the issue either got smaller or ideally went away. I’m finding that as an adult, you cannot always do that. Some issues just will not go away no matter how hard you try to avoid them or how creative your excuses get for why they are not important right now.
Integrating IPv6 into your network is one of those issues. It is a large problem that impacts all areas of what goes on in the IT shop – network, security, applications, content, operating systems, etc. The key to making an integration successful is to make sure that representatives from all IT organizations participate and contribute to the project and to approach the problem by breaking it into manageable chunks.

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.
