[rpd] RE: [afnog] What are the major challenges in enabling Services to run on IPv6?

Hi Malick,

This is kind of a short sighted view in my opinion.  Why you ask?  Because the rest of the world has to go V6 and V6 doesn't talk to V4, unless you want to take a huge step backwards and start running translation mechanisms and other dodgy kludges which will further degrade the African internet experience.

Money is being spent on fiber, wimax and all the other things you mention, in vast quantities.  Infact I would hazard a guess that the investment levels into African infrastructure at the moment are probably outstripping what is being spent upgrading systems in other more developed parts of the world.  That should not stop us trying to get to a point where the internet in Africa has parity with the rest of the world, and parity means we get the V6 in or risk being left behind when the rest of the world goes that way (as they have to do, since there is no more v4).

Further to this, it is far cheaper to implement V6 as the infrastructure is expanded than have to go back and retrofit, if we don't do it now, we'll be facing a HUGE bill later when we're forced to do it anyway

Subject: Re: [afnog] What are the major challenges in enabling Services to run on IPv6?

I was wondering, what good business need is there to push IPv6 to the network edge, specifically in Africa?
What would be the direct benefit to the customer or the service provider, of investing in configuring, deploying and migrating to v6. V4 address depletion is a reality, but in the Africa region, is there really a shortage of IP addresses to assign or is there more a lack of services to run on these IP addresses? Also, wouldn¹t the effort and expense to move to v6 In Africa, be better used, if spent on harnessing WiMax? rolling out fibre where possible? I creasing  Wifi coverage? rolling out DSL/VDSL/xDSL? Increasing peering points? creating alternatives to the current under sea cable transits (and reduce reliance on ACE, etc)?
With the relatively small penetration of broadband in Africa, should not efforts be spent addressing broadband penetration rates and access to information, rather than ³keeping up with the Jones² and rolling out technology for the sake of technology?

In Europe, I am only aware of France¹s Free who have a full native IPv6 deployment, all other providers are managing to provide services without too big an IPv6 footprint. In the Americas, I believe a number of educational institutions have native v6, and most Sps can probably provide it. My contention, IPv6 rollouts globally have been quite low speed and that is probably because there are other priorities for the Service providers.

So major challenges to enabling services on v6, I guess the demand for such services, is probably going to be a major factor.If there is no demand or minimal demand, and a current working system exists, why waste time on it?
Just my 2 cents.
