on peering, transit, and why Vadim should be flogged... :)
Vadim (i think) frist coined the term Tier-N for classifying ISPs. Nice
marketing term.
wrt peering, tranist, and the relative importance of communications channels...
) the PSTN is not ubiquitious ... it is NOT possible to dial and be
connected to
every known telephone number from every/any possible number.
Goverments do
block access to some other places they find objectionable.
) "the Internet" is and (nearly) always has been a collection of
networks, the
interconnection of which is bound by policies. those policies are
there to
restrict/interdict/block traffic of one form or another. (how many of
you
-want- BGP w/o the policy knobs?)
) if communications w/ someone or some entity is critical, it behoves
me to
ensure that such channels are available. that may entail me owning
the ROW,
the transmission media, and the CPE at each end. Or, for less
critical
channels, I might be able to aquire such services from suppliers. For
even
less critical communications, I might even presume that my suppliers
and
their various associates and fellow travelers in the IP pipe business
will
get my various bits to the random places that I try to send them to
on a whim.
And... that the other bits will get back to me. :)
don't want to talk about content. :(

at the length of this thread)
