cc: etosat Hi Gabe- You’ll find a bunch of information in the RFCs published by the [TCPSAT](https://datatracker.ietf.org/wg/tcpsat/documents/) and [PILC](https://datatracker.ietf.org/wg/pilc/documents/) working groups. I’ve cc’ed this response to a new mailing list discussing satellite performance issues ([etosat](https://www.ietf.org/mailman/listinfo/Etosat)) and if you still have questions (eg, if you are looking at performance issues around LEO constellations, you might find help there. Regarding reference implementations, I think it will depend on which performance optimizations you are interested in and that, in turn, will depend on the characteristics of your satellite network.
