Hi Felix,

Sky DeBaun and possibly someone from uDTN should also be listed as the presenters for the BPv7 interoperability testing. The topic should cover (a) summary of current tests completed, (b) discussion of PICS items that are “controversial” based on testing or that cannot be tested in the current round, and (c) writing of yellow book from test results.

Finally, we would appreciate it if this topic can be moved to the afternoon, 3pm or later, since we will be joining remotely and we are 9 hours behind.

Thanks,

Sure, I  have added 30 minutes for you. If you need a bit more, this should also be fine (there should be some slack in the schedule).

@Scott C Burleigh<mailto:sburleig.sb at gmail.com>: Carlo and Tomaso will present some results comparing IP and DTN for lunar comms in the ‘IP vs DTN’ slot.

Regards,

Felix

Hello,

Would it be useful/productive for the DTN/Security working group to hear another presentation on the use of MLS as a key exchange protocol for BP? We would summarize ideas from before and present  new results from two different implementations. It would also be an opportunity to ask questions and provide input/feedback on the Internet Draft for BPSec-MLS (work in progress). If there is interest, we would like to be added to the agenda for a 15-20 min slot during the joint WG meeting.  Thank you!

Best regards,

Xisen Tian

Dear All,

I have drafted a first agenda for the DTN WG meetings in Hamburg. I am sure I forgot some topics and it may not be convenient for all of you (especially for people being remote). I have put in some names with questions marks, please confirm or put somebody else. Times are indicative (let’s say +/- 15 minutes) and we would throw in breaks as needed.

I will not be in the meeting tomorrow but please go and change the agenda as needed.

Regards,

Felix
