[ih] IETF relevance (was Memories of Flag Day?)

I have only a brief moment to respond. The Arpanet, PRNET, SATNET, Internet
sequence gets its primary stability from the sole source funding of ARPA,
initially, and the pooling of resources from other DoD components using
Arpanet. Arpanet was managed by BBN initially (later under contract to DCA
vs ARPA). It really helped that the Internet development funding came from
a single source. Decision making was largely in the hands of the ARPA
program managers, well-informed by the people doing the work. In the
mid-1980s, ARPA, NSF, DOE and NASA collaborated through the Federal
Research Internet Coordinating Committee (FRICC) made up of program
managers from each agency. ESNET, NSINET and NSFNET joined Arpanet as
backbones of the Internet. Again, common purpose welded the effort into a
coherent whole. MERIT played a major role in the NSFNET development which
really elaborated on the multi-network aspect of Internet. MERIT had to
deal with scaling of the Internet to a dozen or more intermediate level
networks linked together through the NSFNET backbone. BGP came out of that
work and has scaled well - now needing more security from abuse/mistakes.

I think there was a common thread in all of this work: people who were
working on different aspects of the Internet and its constituent networks
really wanted this system to work. The goal was interoperability linking so
many different packet switched networks together. Even the Xerox PARC team,
whose work on PUP and later XNS was proprietary, did their best to give
hints to the Stanford development team (mostly me and my graduate students
during the 1974 campaign to specify TCP).

It also helped that commonality and interoperability were key desirable
properties of the Internet system. These were the metrics by which success
was measured.

That's all I have time for now - not sure this addresses your questions
squarely.
