What is the difference between a transit provider and an access provider,
specially in the consumer space? Why is a transit provider expected to
deliver the bits, but the access provider isn't? Since the bulk of
Internet access is actually provided by wholesale providers (e.g.
AOL/Earthlink buy wholesale modem access from UUNET/Level3), who is
the access provider and who is the transit provider?
