[arin-ppml] 2016-3 Revisited - anti-abuse clause

Maybe fairness was not the word I was looking for...

I don't mind large organizations using a more difficult process or
requiring greater proof, as was the case with the "less simplified
provisions of the existing policy" wrt the ISP slow start policy of the
ARIN pool.  But slow start as it is currently written does not work well in
the transfer market.  So instead the specified transfer is granted based on
some hand wavy, future looking prediction with unpredictable results.


Everyone should be able to use a process that is predictable, and not
dependent on hand wavy future looking projections.


For ARIN Pool space, as an ISP, I could "slow start" if I have no history
of utilization, or if my history of utilization is less than my current
growth rate.

In the case of the former I start with a small block (initially /22, later
between a /24 and /22).

In the case of the later, I start with a block size based on my previous
year's run rate (initially a 2 year supply, then 3 month supply, and now
again a 2 year supply).

I use up what I got.  If I can use it in less time than the time window of
space I am allowed to get I can double, if it takes the time window, I get
that size again, and if it takes longer than the time window it goes down.
(plus rounding up initially or down later.)

This approach is:
1. predictable
2. is based on A. actual demonstrable utilization, and B.the belief that
growth will continue
3. does not require product folks to make some sort of hand wavy future
projection
4. does not require ARIN to engage in back and forth in an attempt to
assess the veracity of the projection
5. does not depend on a future looking belief which in the end cannot be
tested, proven or disproven.
6. does not depend on a claim that if not met can simply be excused with
"well, we missed" with no harm no foul.
7. does not reward more overly optimistic organizations with a greater over
supply.

My desire is to permit everyone (end users and ISPs) to use a predictable,
slow start mechanism in the transfer market.

My suggested transfer text differs essentially in three ways:

1. Demonstration of past utilization is slightly easier.
    For ARIN IP space you have to show 80% utilization on average, and 50%
on each block.
    For the suggested text its 80% on average and growth equal to 50% of
the space transferred.

   - the 50% clause is to prevent someone with high utilization from
getting IP space, not using it
     and their now lower utilization still being high enough to get more IP
space.
   - the problem with this approach is someone may actually be growing,
needing, and using the new
     space but have a small historically under utilized block, say a
deployment that got delayed.
   - the growth equal to 50% of transferred space clause it to meet the
intent of the policy while giving
     flexibility to renumber

2. Historical growth may not be a good measure because growth may be rate
limited waiting on a transfer.

   - Basically the first block is "easy".

   - We have a policy to let those with no space to get a /24

   - For those with efficient utilization they can easily double (but not
bigger than a /16).
     If the org never grows it could have up to a 50% surplus after using
this policy.

   - Any org growing at less than the doubling rate will have trouble with
the 80% on average re-certification,
     and will not be able to get another block.
    They could have up to a 50% surplus if growth stops shortly after using
this policy

   - Any org growing at more than the doubling rate needs and is using the
space, and should be able to get more.

  - An org's who is doubling in size, will have trouble with the 80% on
average re-certification, when the growth
    rate drops below doubling.
   They may have up to a 50% surplus if growth stops right after they use
this policy for the last time.

 - An org's who growth rate is greater than a /16 over the time window
(currently suggested as 6 months)
   may have up to a /16 surplus if they if growth stops right after they
use this policy for the last time.

3. An organization will also have to a pay fee for the IP space
   - this is likely a significant deterrent for small organizations
