the Internet Backbone

I frequently teach routing and operations, and find this discussion of
terms to be coming up with a useful consensus to answer some very
frequently asked questions. I'd like to see the results of this discussion
spread more widely than the NANOG list.

It strikes me that the discussion is the kernel of an informational RFC
complementary to Dave Crocker's RFC1775, "To be "on" the Internet." Here,
perhaps we are defining what it means to be "in" the Internet. RFC1775
emphasized the user perspective; it would seem that a different document
emphasizing the operator perspective also would be useful.

Michael Dillon and others have put forth some good definitions. Would any
of you active contributors be interested in trying an RFC on this? I'll
step up to editing it if it would be useful.

I've been fleshing out a longer explanation in my mind last evening so
I'm willing to continue with this.

This is true. The lines of division are somewhat fuzzy. My feeling is
that the Tier 2 provider is not primarily in the business of supplying
transit but may do so incidentally to their primary operations and even
then.
