Re: [sig-policy] Proposals prop-063 and prop-070

Regarding prop-063, I believe that reducing the maximum duration to
six months is a reasonable approach, but it needs to be demonstrated
that any potential increase in the number of requests could be
managed by the current APNIC hostmaster staff. (Hopefully, this
wouldn't simply double the number of requests to be processed in a
year?) This requires an estimate to be made of this likely increase;
could such an estimate be provided by someone from APNIC staff?
You are correct in assuming that the increase in work wouldn't be linear
in scale. Hostmaster analysis shows that smaller requests would be less
complex to assess. Currently, hostmasters spend 24% of their time
processing subsequent allocations. Taking into account the reduced
complexity of requests under prop-063, the predicted workload increase
is 20%.

I think that a distribution showing (Size of request vs. number of
2008 requests of each size) would be useful in terms of identifying
(anonymously) both the number of members that could be impacted by
this proposal, and also the potential overall annual increase to
APNIC requests. This data might allow the tailoring of the scale
described in prop-070 to optimise the benefit of the proposal against
the cost of the additional work involved. Again, could relevant APNIC
staff please supply such information to the list?
See below for statistics on 2008 allocation sizes and frequency.
In summary, I believe that both prop-063 and prop-070 have potential
merit, but both proposals need to be assessed for probable impacts on
APNIC and member workloads, and the detail of the proposals may then
need to be adjusted to take such impacts into account. I therefore
request the APNIC secretariat to provide to this list:
(a) An assessment of the likely increase in number of addressing
requests arising from prop-063;
According to hostmaster analysis, there is a predicted 20% increase in
hostmaster workload (or 0.8 full time equivalent) based on current
hostmaster activity levels.
(b) The (anonymous) data of the number of requests in 2008 identified
by size of requested address block;
Below is the breakdown of 2008 allocations made by prefix size and
frequency of each allocation size:
/10 2
/11 7
/12 16
/13 29
/14 52
/15 53
/16 89
/17 54
/18 69
/19 111
/20 147
/21 187
/22 126
(c) Any assessments as to whether APNIC staffing would need to be
increased to manage the likely workload changes should either
prop-063 or prop-070 (or both) be implemented as written.
For prop-063, as noted above, there would be an increase in workload
equivalent to 0.8 of a full-time hostmaster. We are still working on the
figures for workload changes based on prop-070 requirements and will
post this shortly. But in the meantime, we can say that the reduced
complexity of smaller request sizes under prop-070 suggests that the
workload increase would not be on a linear scale if prop-070 was
adopted, either by itself or with prop-063.
