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…”

With the CDN World Summit coming up this week in London (Oct 26-28), it seems a good time to describe something that’s been a working passion of mine: CDNI, where the “I” stands for “Interconnect.”
What’s CDNI? It’s a new working group within the Internet Engineering Task Force (IETF), co-chaired by myself and my colleague Rich Woundy, Senior VP/Software and Applications for Comcast. The working group mission is to develop standards for the interconnection of CDNs run by different operators, so they can inter-operate and collectively provide a multi-footprint CDN — thereby pooling resources that are owned and operated by multiple operators.
It’s all about how to link up the world’s CDNs, so that they can exchange information and work collectively. Just like the Internet was about linking up the world’s IP networks.

It was only a matter of time before DOCSIS 3.0 swept the cable industry. The benefits that DOCSIS 3.0 IP capabilities can deliver—more content, more mobility, more personalization, all at a lower cost—are simply too great to ignore. That industry evolution is now picking up speed, and I’m happy to report that Cisco is leading the pack in DOCSIS 3.0 technologies.
LightReading recently published quarterly market share estimates for August 2011. The upshot: Cisco is maintaining “a hammerlock” on the CMTS market, with a global market share of about 60 percent.
ACG Research (ACG Market Release 2Q11 Worldwide Video Infrastructure) found similar results, stating that Cisco’s CMTS market share grew by nearly 3 points last quarter to a commanding 65.8 percent of the market. Read More »

IPv4 addresses have run out. Many service providers today are implementing or beginning to plan for the transition to IPv6. One service provider at forefront of this activity is Comcast, one of the nation’s largest video, high-speed Internet and phone providers to residential and business customers. Starting in 2005, Comcast began putting together deployment plans for IPv6 in order to address the IPv4 address run-out and to be ready to offer their customers new services that take advantage of IPv6. The Comcast IPv6 program is run by John Brzozowski, Distinguished Engineer & Chief Architect for IPv6. Read More »
