Dear All,

We suggest to meet in D1.023 for that meeting at 15:30 (unless someone has a bigger room, we have about 40 seats and are about 20 people).

Regards,
Felix

Would this work for you all?

Dear Olivier,

As I am urgently waiting for this functionality, the meeting is an excellent idea 😉

I am even wondering if someone from the Cloud WG should be involved as they are currently looking into data formats (eg, frame files + metadata) where we could have a lot of commonality (I have seen that you also indicated the terrestrial side in your slides and it may fit nicely).

We have discussed this briefly in the DTN WG meeting today and would propose a 2h meeting maybe Tuesday or Wednesday pm.

Regards,
Felix

Dear all,

We had discussions between the DTN and MOIMS-SM&C WGs concerning a “CCSDS Delivery Agent” in charge of a “First Hop” and “Last Hop”, described in

•        [1] sections 6.5.3

•        [2] section 6.6

During the discussion, it appeared to SM&C that it could be seen as a way to coordinate supports in relay operations within a DTN Network (or even not DTN?)

We would like to organize a joint meeting with the following questions:

-         Is it something CCSDS should work on?

-         Is it framed correctly? If not, how can we improve?

-         How should we coordinate between the relevant WG?

As it deals with cross-support, we thought CSS should be involved.
As it deals with DTN, DTN-SIS needs to be present.
As it seems a very wide topic, SEA-SA would be needed to help us frame the topic.

We (SM&C) prepared the slides that are attached to this email to support the discussion.
We are still working on realistic use cases from our agencies’ experts.

When this joint-meeting could happen? On SM&C side, we haven’t set our agenda, so we have no constrain.

Thank you
Olivier, for MOIMS-SM&C
