end users view networks as a business overhead expense and are unlikely to needlessly spend money on networking technology without a solid business motivation to do so. I went on to explain that IPng is unlikely to be deployed by us end users unless it becomes bundled with a business requirement, the most compelling of which would be a new Killer Application that demanded IPv6 capabilities in order to function.Fully agreed. This is particularly true for IPv6 deployment in last ten year - failure to find a killer application. A right business model is actually more important than technology itself.
Solid business motivation - your providers wants to increase the service provisioning fee since they have to pay for the public IP address
Killer aplication - Internet Protocol (with version independent applications)
Unless this changes in the future, IPv6 will continue to not be deployed by end users despite the efforts of Apple and Microsoft and others to ease its adoption. But then, since not all ISPs support IPv6 today and the DFZ Internet is currently unprepared for the BGP scaling problems that would arise with a mixed IPv4- IPv6 infrastructure this is probably A Good Thing.This is a real issue which has been ignored by IPv6 community for years. My guess is IPv6 community does not want to discuss this because it may even more block IPv6 deployment. However, it is time for us to face it and solve it or avaoid it.
According to our findings in our IPv6 deployment: - deploying IPv6 on backbone network is easy and relatively painless- deploying IPv6 on access network is not obvious, but can be done in scalable way - deploying IPv6 at customers is very painful - very conservative application owners are hindering of introducing IPv6 even when their application cannot support it....
- deploying IPv6 at home has showstoppers: no IPv6 capable CPE under 100 USD. After introducing such a device - at least 10 years is necessary to the users to replace older devices.....
I personally *HOPE* that IPv6 will become deployed -- after all, I spent many years helping to create it. But my experience with pre- TCP/IP protocols (I used to be an SNA and BSC "expert") is that even if IPv6 becomes widely deployed, IPv4 will endure for a surprisingly long time (decades).Yes, it will be years. I believe the whole internet society has accepted this and be prepared for a 25+ year co-existing period.
Agreed. Best Regards, Janos Mohacsi
