The data owner (the content provider) is often not the owner of the
distribution network/system. That's all that I think Ian means by "outside
of the administrative control of the data owner."
Our discussions about CDN peering have pushed this separation between
content and distribution one step further, to the idea of distributing
content onto networks not directly contracting with the data owner, but
(say) acting as subcontractors, or in other similar arrangements.
I don't know if such arrangements would strike you as "explicit
instructions" from the content provider (indeed, part of the value is in
hiding the seams of such distribution-provider cooperation from the content
provider). But I have trouble identifying the illegitimate part of such
arrangements.
I don't mean to be argumentative (yet ;-)), so if you do mean to say that
such subcontracting of content distribution is evil, then please help me out
by elaborating a little on why.
I think that your two-piece division (how content is advertised; how content
is found) is fine as far as it goes. I'd claim that CDN peering deals with
refining each of those two parts to fill in the details of how they should
work in the presence of multiple administratively-distinct networks that
nevertheless choose to cooperate.
Feel free to explain to me that I'm missing your point. I have a sense that
you're vigorously attacking as illegitimate something that I see as a
technically challenging but ethically sound goal, so I suspect there's some
sort of misunderstanding here.
