<p class="MsoNormal"><span style="font-family:"Calibri",sans-serif">Thank you for pointing to this. Actually myself and the DTN WG in CCSDS have been closely following the path from the formation of the former deepspace non-WG to the current tiptop WG, so that
we are quite aligned on what’s happening there. As also signaled during previous CESG meetings, our concern is the direction that this WG is going to take and what kind of recommendations will be able to formulate, given the fact that it will consider pure
IP networking with a profiling for QUIC (i.e. BP out of scope), whereas the space community and CCSDS has invested considerable effort on DTN in the last 20 years. But let’s see…<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-family:"Calibri",sans-serif">You might be interested in the link below. IETF has formed a new WG that is focused on adapting IP for deep space, primarily by, from what I can gather, tuning Google’s QUIC protocol which
has gained a fair amount of terrestrial usage (see RFC 9000 for more on QUIC). If you follow the link, you may notice that there is mention of coordinating with CCSDS.<o:p></o:p></span></p>
