This highlights two different transition milestones, I think:
* Moving from a network of independent hosts (machines) to an
internetwork of independent networks.
* Moving from a monopolistic backbone model to a competitive
I've always understood BGP to be significant for the latter.
I've also understood that there were some non-BBN IP backbones, before
NSFNET but that routing for them was done in a very hand-crafted manner,
and that NSFNET served as a forcing function to produce a routing model
that comfortably supported multiple, independent and competing backbones.
The point about alternative models for (administrative? topological?)
structuring of a backbone's internals (hierarchical vs. non-) is
interesting. Might be worth expanding on that...
