Top heavy write-up, with lots of intro & set up. Good stuff, and was happy to see it covered.

And talks to really good really neat wins! Simulated in-process network, tapping Quinn's AsyncUdpSocket and UdpPoller. Cool, nice. Better debugging with pcap, nice. Determinism, nice.

I do want a bit more of an ending though! Glad to see the work open sourced. +1 the thanks to Marc Blanchet for all his help & pushing that push. Also very fun reading their draft (linked in post), An Architecture for IP in Deep Space, https://datatracker.ietf.org/doc/draft-many-tiptop-ip-archit...

> How can QUIC be viable, then? The attentive reader might already have spotted the answer: the problem isn’t QUIC, but its default configuration, which was designed with terrestrial internet in mind. What we need is a custom configuration, this time targeting deep space, with guidelines to tweak things further if a space mission deems it necessaryy.

I'd expect that there's a ton of work for "bandwidth shaping" interplanetary QUIC that's probably missing, even if it just needs to be basically nulled out on the way across the x-mitters. Guess it's open source & I can dive in & see what was done here!
