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…</span><span lang="EN-US"><o:p></o:p></span></p>
