The Internet Address Well is Running Dry

September 2, 2010 - 0 Comments


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.

Powered by the Cisco QuantumFlow Processor, with parallel processing, the ASR 1000 Series scales to millions of address translations, with gigabits of throughput for CGv6 functionality. Being highly programmable, it delivers fast feature velocity in a compact form factor. In-service software upgrades make the platform highly reliable.

In addition to the ASR 1000 Series routers, Free leverages the CGv6 capabilities on other SP network components such as the Cisco CRS and Catalyst 6500 Series to deliver IPv6 to is customers.

To further ease transitions, the Cisco Services for IPv6 offering enables service providers to migrate to IPv6 in a controlled, safe, and cost-effective manner—thereby reducing the risk to your business. Cisco’s track record in successful IPv6 implementations across the world led to development of global best practices.

Now the Internet well can remain truly bountiful, with apps, browsers and email clients humming along just fine.  Keep on farming!
