there is now a burgeoning body of literature with results on
network coding, and on generalized packet swarming techniques that show
that if you want to build a data network for today's dominant
traffic sources, then you can do very well without any complex resource
allocation in the sense of admission control, scheduling, OR routing, and just
rely on the codes to do the right thing

such a network depends on packets, not circuits, fundamentally, but is very
different from today's internet (as different as IP is from, say, ISDN)

however, right now, it is totally unobvious how such a network would carry
a phone call:)

its also not at all obvious what an "end" is in such a network, so there's no
point in discussing it on this list...

in a wireless network, BER is probably not a terribly good metric for quality -
actually the idea of a "link" is not terribly helpful either, which kind of makes
the idea of a "hop" fairly redundant, which makes e2e v. hbh a sort of
angels on the head of a pin type irrelevance too

such fun
