On a much smaller scale, it seems to me that the self-organizing network
of our packet experiments of a few years ago followed the same basic
principle. When I sent a packet from McLean to San Francisco, the
routing for that packet was not written anywhere. It kept trying various
paths until it found a way to reach its intended destination. This was
all happening, of course, on one or two frequencies (145 something) but
one could have added frequency band change e.g., if VHF does not work,
try HF, etc.), format change (from packet to say PSK31 on HF) etc.
until an acknowledgment was received . This haphazard approach to
routing was extremely wasteful of bandwidth and resources, but certainly
worked.
