It explains the emphasis on their flawless operation. Both perspectives set the bar for new technology adoption: funding its deployment requires strong business cases, and approving its integration requires assurances that it will not impact the existing, revenue-generating or supporting infrastructure.
Making the case for the adoption of a foundational transport technology such as IPv6 is particularly challenging, in the context of the two perspectives mentioned above. After all, this new version of the Internet Protocol has only a few enhancements–which, to people outside the “IPv6 lovers or haters” communities, may not really amount to much of a business case that would justify resources being spent for an upgrade. Moreover, the natural expectation is that this new infrastructure protocol will have an impact on the existing network. So, why should an organization even look at IPv6?
To answer this question, we first need to remember that today nobody really questions the benefits of the Internet and the need for its continuous growth. IPv6 is essential to sustain this growth, to get more people and devices connected to the Internet. This perspective underlines the fact that IPv6 is NOT a feature, but instead, the fundamental IP network layer of the TCP/IP model developed to support end-to-end services and network transparency (which succeeded to end of life most of the 1970’s proprietary protocols such as Appletalk, DECnet, IPX, SNA and others). Any attempt to build a business case for IPv6 must take this into consideration. IPv6 is not the answer to all technical problems faced by the Internet, but it provides the resources for its continued growth–and that translates into business value.
Premises for building a business case for IPv6
The IT industry finally came to the realization that uncovering the “IPv6-based killer application” may not be the critical element in considering IPv6 adoption. After all, we should look not only at “What is the new thing that IPv6 adoption will provide?”, but also “What will we lose if we don’t adopt it?” The impending IPv4 address space exhaustion is clearly supporting this perspective and helping the case for IPv6. But, at first glance, this may not be a concern for some organizations. Moreover, ten years of experimental and trial deployments built sufficient confidence in the protocol to safely consider its integration in production environments.
At this point in time, the perspective taken on building a business case for IPv6 adoption depends less on the technology details and more on the priorities of an organization, its business model, and the market in which it operates. Let’s look at the following six examples of case studies we discuss in our book “Global IPv6 Strategies: From Business Analysis to Operational Planning,” Cisco Press (2008):
1. Comcast example: Performing the same as on IPv4 but on a larger scale
When reviewing the business growth opportunity and forecast, an organization dependent on the Internet for its revenues must investigate the value of the “infinite” IPv6 address space to sustaining business growth. This is one of the primary drivers for IPv6 adoption, and it is exemplified in the Comcast case study.
2. Bechtel Corporation example: Operational cost savings or simpler network models
A business not directly related to the Internet, but highly dependent on the flow of information, is always considering improvements and optimizations to information availability and distribution. IPv6 helps large organizations with operational cost savings and optimizations, as they have to keep up with a growing geographical footprint, constantly-changing network topology, and an increasing number of networked devices. The Bechtel case study shows how a multinational organization can benefit from IPv6 adoption.
3. NTT example: Deployment of Internet Protocol Television (IPTV) services
Another example would be walled garden services from ISPs such as Tokyo, Japan-based NTT (Nippon Telegraph and Telephone Corporation). When deploying IPTV services, including HDTV (High Definition TV), streaming over FTTH (Fiber-to-the-Home) to several devices sitting on a home network, a choice between IPv6 Multicast or NATed IPv4 Multicast led to an IPv6 end-to-end model simplicity.
4. ArchRock example: Leading the innovation – no IP legacy – new business
IP convergence is not just the buzzword du jour; it is reality for voice, video, audio and data traffic. The convergence process will continue, regardless of the version of IP used for transport. For this reason, all innovative businesses relying on IP-based data exchange should look at integrating IPv6 support from day one on all new products. They should also consider leveraging some of the key features of the technology. The ArchRock case study provides an example of a startup relying on IPv6 to provide another level of convergence: sensors communicating over IP.
5. U.S. Federal Government example: Preparing the future
Nobody doubts that IPv6 will be adopted, and that we will slowly transition to it. Even if this is a long-term project, organizations such as the U.S. Federal Government (which is known to plan projects having a 20-year duration) must evaluate emerging technologies which may become mainstream during the life of the project. This has to be done to avoid major restructuring during the life of the project.
6. Cisco and Command Information examples – Opportunities to win or lose business
When evaluating business opportunities, organizations should also look at the potential loss that may occur due to an inability to address customers’ requests related to a technology unfamiliar to interact with its vendors or partners. A business can drive the market by showing how the technology is used internally and how it consolidates its growth by offering products and services over both IPv4 and IPv6. This perspective is described in the Cisco and Command Information case studies.
In conclusion
The above-mentioned considerations underline the fact that, at first sight, the business case for IPv6 is not a trivial one to make. This is typical for a fundamental technology. IPv6 has, however, the potential to sooner or later be an inflection point in the evolution of the Internet, the global economy and many businesses. Regardless in what market your organization operates, the case for IPv6 adoption is easier to make if you take into consideration your business and operational model, along with the basic technology considerations.
