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 »

The Edge of the network is a major focus for our customers, the market as a whole, and certainly for us at Cisco.  The ASR 9000 System is the leading Service Provider Edge router in all three cases, and admittedly, the system is on quite a roll.

In our June ASR 9000 blog, we announced to the market the newest innovations in the platform – nV technology and the ability to scale the system to a whopping 96 Tbps (more than 36 times the capabilities of the nearest competitive platform and enough bandwidth for man, woman, and child in Beijing, London and Moscow to watch a streamed High Definition movie simultaneously).  Along with that news, we had the honor of announcing five new customers joining the 500+ strong ASR 9000 family — China Telecom, NTT Playa in Japan, Tata Communications in India, Fastweb in Italy, Cox and Comcast in the US.
