[ih] SATNET (seismic data, Norway, UK)

The design contemplated multiple networks and alternate paths from the
start. The configuration of the 3 net test artificially forced traffic from
PRNET to ARPANET toSATNET to ARPANET again. The routing protocol in ginny
strazisar's gateways was distance vector and I believe would handle multiple
paths and backbones. V

Vint,

My understanding of the original Internet work was that openness meant
independent technology (and administration) for the individual leaf
networks,
but that only one backbone -- now called default free zone -- could
initially be
supported.

I believe there were some manually-configured alternate backbones, but that
easy
addition of more than one had to wait until NSFNet was started and that that
finally forced creating BGP, to support multiple backbones.

Does this view at all mesh with reality?
