The Internet Address Well is Running Dry


What would you do if you launched your Internet browser or your favorite Internet application or your email client, only to find they all have stopped working? Imagine all the virtual farms whose crops withered on the vine because you couldn’t harvest them on time.

It is a fact. The IPv4 Internet address well is running dry. The IPv4 exhaustion countdown timer shows that service providers worldwide have less than one year to prepare their networks for this inevitability. What are service providers going to do to maintain the health and viability of Internet?

One Internet Service Provider (ISP) in France is leading the way. Free (Iliad Group) already has a working solution. Free, the second largest ISP in France uses Cisco’s CGv6 solution to deliver IPv6 to their customers. Free residential broadband customers are now experiencing the IP Next Generation Network (IP NGN) in one of the largest live IPv6-enabled residential Internet service deployments worldwide. Free customers will benefit from Internet connectivity that can scale to meet the ever-growing number of devices and applications.

Cisco enables service providers to manage the transition to IPv6 with the Carrier-Grade IPv6 Solution (CGv6). One of the CGv6 components is IPv6 Rapid Deployment (6rd). The 6rd component is a mechanism to facilitate a quick implementation of IPv6 across existing IPv4 infrastructures of service provider networks. It is derived from Cisco 6to4 Relay Service by configuring IPv6-enabled routers to establish automatic 6to4 tunnels and ensures the manageability of the Internet mitigating IPv4 address exhaustion issues.

Free has taken an innovative approach to cost effectively deliver 6rd service by relying on existing Cisco infrastructure and utilizing the integrated 6rd gateway services functionality on the Cisco ASR 1000 Series.

SXSW 2011: TV Turbulence and Transformation

sxsw south by southwest

As touched upon in a recent Platform post, in the proposed panel topic we contributed for the upcoming South by Southwest interactive conference (or SXSWi for those in the know), we’ve jointly posed several related questions about the shifting dynamics within the traditional video entertainment sector: How will newer over-the-top solutions like Hulu and Netflix co-exist with other members of the ecosystem? Will the fragmentation we’re seeing unify?

In a recent IPTV News interview, Anthony Rose, CTO of Project Canvas, shared the following insightful point of view that offers one likely scenario for creating a platform that supports new patterns of video entertainment consumption (note the emphasis is mine…though it would be cool if you could actually speak with underlines).

“So I think that finally we’ll be seeing a massive change in VOD consumption, but on TV sets, not just on computers, and one of the key things for me is that the technology is almost slightly less interesting than some of the big picture drivers, the social factors: as today what you choose to watch is driven by what is on at the time, so it is the scheduler that is driving things, but if you switch on a next-gen TV, let’s say a Canvas box, and it is filled with favorites and recommendations as soon as you switch on your TV, you may find that the driver of usage starts switching in a rapid way.”

Consider it a SmartTV or TV Concierge of sorts. In fact, we’re already beginning to see the start of a transformative trend in the shift of consumer behavior – from watching scheduled linear TV, to increasing on-demand viewing. Here in the U.S. marketplace, the continued Netflix subscriber growth projections are perhaps a key indicator.

Also, we’re seeing an increased emphasis on attracting independent TV app developers and arming them with the open APIs and SDK tools they need to apply their creative talent. While high-profile efforts such as the recent Samsung “Free the TV Challenge” has gained lots of media attention, forward-looking pay-TV service providers are equally engaged in this evolving trend.

IETF-78 Update and Discussion Towards IP Addressable Smart Objects

Just returning from a very busy week at the IETF-78 in Maastricht, Netherlands. One of the greatest IETF milestones celebrated at IETF-78 Maastricht, was DNSSEC signing of the root zone.

I had participated at a Bar Birds of a Feather session [Bar BoF] on cloud computing.  With over 110 individuals interested in the discussion it would be difficult at best to classify the meeting as a Bar BoF. The discussions focused on problem framing; potential applicability of IETF-based protocols, and development of IETF-based protocols therein.

I would expect more discussion on the related IETF mailer at, as we prepare for IETF-79 to be held in Beijing.

By the way, the ITU-T Focus Group Cloud Computing meeting will be held September 2-6.

Switching gears a bit, to the Internet of Things (IoT), my colleague JP Vasseur along with Adam Dunkels have just published a book on the topic entitled, Interconnecting Smart Objects with IP: The Next Internet. IoT traverses several key adjacencies such as Smart and Connected Community, Smart Grid, Smart Automobile and so on.

Research continues to develop in wearable computing and in skinput technology.

How 6rd Eases the Transition to IPv6

A CNN headline finally appeared last month on IPv6, “We are running out of Internet addresses.” Meanwhile the American Registry for Internet Numbers (ARIN) has stated the bottom-line very clearly — with less than 10% of IPv4 address space remaining, organizations must adopt IPv6 to support applications that require ongoing availability of contiguous IP addresses.

The full network transition to IPv6 constitutes a significant ongoing project for service providers, so most have been seeking practical methods to help smooth the rollout process. The very timely IPv6 Rapid Deployment (aka 6rd) standard is a proven method for incrementally deploying IPv6 in large scale networks, and it’s now been approved for publishing as an IETF Standards Track RFC. Cisco is the first vendor in the industry to have live customer networks using its standards-based 6rd implementation of this technology.

6rd enables a service provider to accelerate the implementation of IPv6 services to existing IPv4 sites where it provides customer premise equipment (CPE). This approach utilizes stateless IPv6 in IPv4 encapsulation in order to transit IPv4-only network infrastructure.

IPv6 Rapid Deployment (6rd)

Most importantly, unlike an appliance based solution, the economical Cisco solution does not require additional systems-related cost, space, power, etc.

Cisco announced the Carrier-Grade IPv6 (CGv6) solution last year in anticipation of the accelerating industry requirements for solutions to ease the transition. The solution offers a systematic outline to Preserve, Prepare and Prosper during the migration with specific technologies and customizable services. New innovations on the CRS and ASR platforms allow customers to gradually move towards an IPv6 future. The Carrier-Grade Services Engine (CGSE) on the CRS platform provides massive scalability for CGv6, while the ASR 1000 with parallel processing on the Cisco QuantumFlow Processor delivers fast feature velocity without separate service blades. Additionally, Cisco’s service provider product portfolio has been supporting IPv6 as a dual-stack technology for some time. Our customers can enable IPv6 — in addition to running an IPv4 protocol stack — without affecting performance.
