I don't think this list is the right place to
conduct that particular
debate.
Not disagreeing; my message was a very short gloss on a very complicated
situation, and I wasn't trying to push any particular position, just pointing
out that work (whether the right direction, or not, I didn't opine) had been
done.
Its true RSVP didn't get traction, but the
economics which underpin it
are pretty bad, for the current Internet model of settlement
Yes, but would _any_ resource reservation system, even one that _was_
'perfect', have caught on? Because:
it would not surprise me if there is ... more dropped
packets than
strictly speaking the glass expects.
This is related to something I didn't mention; if there is a lot more
bandwidth (in the loose sense, not the exact original meaning) than demand,
then resource reservation mechanisms buy you nothing, and are a lot of
complexity.
While there were bandwidth shortages in the 90s, later on they pretty much
went away. So I think the perception (truth?) that there was a lot of headroom
(and thus no need for resource reservation, to do applications like voice)
played a really big role in the lack of interest (or so people argued at the
time, in saying IntServ wasn't needed).
