Comcast Successfully Deploys Cisco Network Registrar for DHCP and DNS Services for IPv4 and IPv6

By David Flesh

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 »

Network Service Providers Can Compete and Win in the Cloud

If you’ve been following the research from Cisco’s Internet Business Solutions Group, you may have already seen the survey on Service Providers and their viability in the Cloud at the end of last year. Yesterday I was preparing for a customer briefing when this report came to mind and I thought it may be useful to summarize the high points if you haven’t read it yet.

The custom research found that Network Service Providers have an advantage when offering Cloud services if they use their unique assets to differentiate their services. Over-the-Top (OTT) players may have seen success in offering plain vanilla Infrastructure as a Service at large scale and low prices but the opportunity for supplying the high-end and high-value spectrum of Cloud services is still underway. You will probably agree with me that security is critical for any service these days. It is a challenge that requires proper design and planning and proper vigilance and quick responses are what differentiate the winners from the losers. Cloud is a large market in the midst of a transition and it will be fun to watch how everything plays out, I’m placing bets on the Service Providers to scoop up a valuable share of the ~$43 billion XaaS market by 2013.

Charter’s Bob Hunt Talks with Cisco on their New Network

Yesterday we announced that Charter Communications, a leading broadband communications and entertainment provider and the 4th largest cable company in the United States selected the Cisco CRS-3 and ASR 9000 as part of a major network upgrade. This of course brings up the question our readers often ask – why? What is driving these investments? While we have our perspective (which we share regularly on the SP360 blog and other forums), it’s even better when we get the view directly from the customer.  To that end, we had the opportunity to  interview Bob Hunt, Charter’s VP of Network Engineering on Charter’s perspective on the network upgrade, the drivers, and the growth in DOCSIS 3.0 usage and the network efficiencies he’s forecasting.

Momentum in the Edge

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.

Machine-to-Machine Communications as a Subset of Internet of Things

As I have blogged on the Internet of Things and Web of things in the past, I would like to focus my forthcoming blogs on Machine-to-Machine communications and its implications to the network, to protocols and security.

Let’s set the foundation:

Imagine a world where billions of objects have sensors to detect, measure, and assess their status, all connected over public or private IP (Internet Protocol) networks.  This world of interconnected objects would have its data regularly collected, analyzed, and used to initiate an action. It would provide a wealth of intelligence for planning, management, policy and decision-making.

Important information is pushed out to machines, to individuals, and to organizations of every type anywhere in the world. The term that characterizes this world of interconnected objects, is the Internet of Things or IoT. Read More »
