We must be talking about two different Internets.

In what way overloaded? Do you have any pointers? Proof? Data?

Dear Kurt Eric,
Let not play this, please. Either you think after careful personal 
study (or you believe) that the current system is the best solution 
the world needs, and that it only calls for some users to be more 
educated in using it - and we are on planets apart. This is fine with 
me, and the end of a non existing debate.

Or you think the DNS does not match the IETF "core values" in being 
centralized (I do not make that "core value" as described by Harald a 
creed, I think they are often outdated, but I fully agree they are a 
technical minimum). And, together with ICANN, you think IETF is the 
right place to respond ICANN's call for more (ICP-3). So you try to 
understand the problem and to imagine solutions. This is what we did. 
And I explain the solutions we are subsequently working on.

The problem we face is an old and too large unique system with a
robust yet overloaded engine. With all the problems which come with
it. We have to split the zones of usage and risks. Either it is
planned by IETF or it is done by the users. I suggest it is done
together.

Again, overloaded engine in what way?

I just report on our follow up on this premise. If you do not see it, 
I cannot help with details. Just with the alternative. Yu are the 
judge.

The DNS "engine" is made of all the root/name servers and resolvers.
- either you are satisfied with their present tools, organization, 
limitations and resulting service, then again I cannot discuss it.
- or you are not, and then the question is to know if your 
disatisfaction results from the used solution or from the way this 
solution is implemented.

IMO the problem is not with the solution (software) but with its 
architectural deployment and usage. This permits a smooth transition, 
using existing and proven building blocks and expertise. But I think 
that speed if the essence. One may also disagree.

Then the agreed file
Agreed by whom?  In what way?

Let me elaborate quickly. The target is not to obtain a file which 
pleases anyone as today, but a file which reports on the TLD Managers 
entries. So, the point is not who does it but the number of identical 
independent results. What follows is for one single national service.

- National because of the legal and political aspects in many aspects 
(risk containment, sensitive information intelligence leaks, justice 
obligations, etc.).
- But subsidiarity applies to the regional, local, corporate, private 
granularities (I explained what this means in my first mail).
- this means that security and verification will probably repeated 20 
to 50 times accross the world. Once a day in each country could mean 
every hour for global issues such as the DNS (the protocol is the same 
for every root information [time, radio frequencies, weather, hospital 
situation, etc])

The process we retained is to have at least four different independent 
data collection processes (whatever the processes, starting with a 
simple duplication of the NTIA file in the case of the DNS legacy 
root). The reason for at least 4 is to have at a majority if needed, 
even if one is down.

There must be five conditions for the result to be accepted (there 
could be more?)
1. there must be no reported alarm (nominal situation) on our 
monitoring system
2. all the results must be identical
3. there must not be an abnormally large difference with preceding 
copy (variance max to be tuned from experience) - to allow reasonable 
updates if permitted.
4. visual review by the four collection managers is positive
5. there must be no significant (similar to 3) with other partenering 
root files on common part of the root matrix.

If these 5 conditions are not met there will be an investigation and 
concerted agreement to be reached among collection managers, or a "no 
go" and escalation to Execom and to BoD (or Gov). These conditions (or 
more) can be made legal and imposed before a State endorses a Root 
Service for its own use and for legal transactions.

There is a possible alternative: the decision of the Government in 
case of national vital crisis. The role of the collection managers 
will be to advise how to reduce pollution in such cases - this may 
call for international concertation [exemple: the "ambassador lounge" 
at ITU (telephone is real time, no 48 hours delay). A doctrine is to 
be set-up as part of Digital Warfare (US say Cybernetic Warfare). 
Experience in Mines, Electronic or Nuclear Warfares shows this is 
possible.

You want to reduce the calls to your system, right? Let stop the
"cache" idea which is something of _your_ system ibn theirs, and
propose them an update of _their_ system - like anti-virus updates
(ever heard that anti-virus run huge 50x1G systems? And let discover
what a user system can bring more to its user owner. So when the 
user
has started using and enjoying _his_ system, you will obtain what 
you
want.

Why would I want to reduce the number of calls on my system? My 
system  is doing just fine...

What is your system ?

In the case discussed the problem is the current increasing load on 
current servers. That load and that type of calls are inappropriate. 
The architecture is to be changed (all the more than it permits DoS). 
Keeping daily updated files of much larger size than the root file is 
carried by many people around the world more efficiently, more 
securely and with less of constraints to innovative usages.

But again, the very nature of the DNS permits such transition to be 
transparent. So if you love the current architecture, it is OK with 
me. As long as you do not pollute what we do and we do not pollute 
what you do there is no problem. This discussion only concerns those 
(with ICANN ICP-3) who want to experiment and work on the resulting 
experience, towards a better response to the people and Gov demands.

I just describe what we have started working on, with scarce 
resources, along those lines for more than two years. And what we 
target from then on.
