With all the jibber-jabber about Starlink being down, I figured it was an appropriate time to remind people this exists. Vint Cerf, one of the founding wizzards of the internet, established the IPN SIG in 1998 to cuss and discuss issues related to IP protocols over high-latency, potentially high-loss links. Worth poking around if you've not seen it before, though I sort of wish there were more use cases regarding information security.

IMO the most likely solution to interplanetary networking is to throw tons of datacenter and compute that's anywhere more than a few light-seconds from the nearest existing datacenter, then use something along the lines of IPFS to perform data synchronization between planets.

Author of the initial versions of DTNPerf (iperf for DTNs) and some related papers. I moved on to other areas of SW engineering, but glad to know DTN technology is still looked after. I recently learned that ESA are looking into that as well.

There are too many graphics (>0) and not enough monospaced font for me to take this seriously.

Could quantum entanglement eliminate the delay?

I was at UCLA with Vint Cerf ... very cool guy.

"We work to extend terrestrial networking into solar system space..."

Minor nitpick: it's the Solar System - i.e. capitalized (since it's a proper name). The Solar System is the planetary system that we reside in, the one that has the star Sol at its center.
