I have seen recently formulations of some ambitions towards adaptation of some protocols (ND timers, but also other protocols at lower layers) to work on longer latency IP hops, like in UE-to-sat comms. This is some times at 3GPP, other times at ESA, and probably others, I cant remember precisely. At IETF there is now this TVR WG (time-variant routing). Earlier there was DTN (delay tolerant, disruptive, networking) with 'bundle' networking but it is no longer active. There is also this 'ATN' (Aeronautical Telecommunications Network) a concept that considers sometimes satcom. I suspect this project 'QUIC in Space' might be related to the very active context of satcom constellations (starlink, oneweb, kuiper, marathon, iris², and more) but I dont see them mentioned. One might wonder whether we'll be seeing at IETF the aerospace domain more homogeneous, or more fragmented.
