Oleg,
Glad to see we are converging, a bit.
...
But, irrespective of this detail, isn't it reasonable to use the
number of (live) ASes as the basis for
the number of pub points (CAs)? To first order, any entity that needs
to be explicitly represented in the
RPKI is associated with an AS#, whether they are an LIR, a PI space
holder, or a multi-homed holder
of PA space (from an LIR).
I don't know. I see that the 1 AS = 1 CA is often referred as reasonable.
But I do not see why an AS operator, using single AS#, cannot serve
multiple organisations that got their address space from somewhere else.
So all these organisations will have CAs, will create ROAs, but would
not operate own ASes.
In what sense do you mean "serve" here? Do you mean that the
organizations in question have, for example,
PI space but no AS#'s, and thus their ROAs all point to the AS# of the
AS operator? Is that common?
Also, I should amend my comment above, slightly. When we model the
number of pub points (CAs) we do
add in a factor to account for orgs that have allocations from multiple
sources, but may be represented
by a single AS#.
