[CESG] [EXTERNAL] Re: IETF forms "tiptop" WG -- Taking IP to Other Planets

We were discussing that very problem yesterday. I think the orange book was closed with conditions pending/unsatisfied (Ignacio raised some questions about zero bundle nodes, anonymous bundles, etc.)

So it still needs to go to Agency Review and CMC review

Yes indeed it is very unfortunate that Tom stepped back now with BPv7 orange book almost ready for publication. I’ll check later with Tim and Sami (here in cc) how to make sure the publication process is not much delayed.

Best Regards,

Tomaso

Hello Tomaso,

Very good to hear that you and the DTN working group have already been following this.

I will note  that we (CCSDS) are of course very close to having BPV7 published. It is indeed very unfortunate that Tom Gannett somewhat abruptly retired at this time. Perhaps a suggestion is that CESG should express some sort of priority for picking up the work and getting key publications such as BPV7 out the door. I think that should have priority for whoever is picking up the work.

Best regards,
-Erik

Hello Erik,

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…

Best Regards,

Tomaso

Tomaso and CESG Colleagues,

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.

Best regards,

-Erik
