in the harsh realities such as
o a significant portion of the internet's isps will not publish
peering and customer business relationships,
o ASs are not homogenous, A gives B local peering and international
transit in frankfurt, but B may have no relationship with A in
new york, or B may be A's customer in new york, and you will never
know (and you do not want to see how this is done if you are
anywhere near a meal)
o etc.
could you point to where two such systems are documented?
otherwise, i have to conclude that
o this is just a repeat of the non-sense which wasted years of time
of the last ietf attempt in this area,
o and we should do what we know how to do, which, though not a total
panacea, will be a non-trivial improvement on the current situation,
and
o and we should leave the research to an irtf wg.
