>That's exactly the fundamental concept behind Iridium and several more constellations since, Starlink perhaps most familiar to the most HN readers. This isn’t at all a fundamental concept special to space. This happens all over the ground (smart networks tolerant to faults). Routing protocols, packet switching, multiplexing, link layer authentication, etc were all before SDI. Any special sauce for iridium or Starlink has nothing to do with the nodes being active routers.
