[Sis-dtn] SIS-DTN Input to SIS report to CESG

[Felix Flentge]

Hi Bob & All,

Thanks for chairing the intensive DTN meetings; I think we have achieved very good results aligning with mission needs in view of the limited resources!

I have a few minor comments on the slides (if it is not too late):

Slide 2: Hooke Transmission Protocol, need: please add ‘optical communication – W’
Slide 3: BPSEC security profile: I am not sure if it will be a profile of RfC 9173. IMHO, we should try to align with CCSDS 352.0-B-2 CCSDS Cryptographic Algorithms (which may turn out to be similar to RfC 9173) + maybe COSE.
Slide 4: Hooke Transmission Protocol:

  *   I am fine with the proposed name but I assume that should be agreed at CESG / CMC. I would also like that Jeremy has a say as he spent a lot of time working this out.
  *   I am not sure whether we achieved the 30 Gbps or not (10 we did for sure; higher rates are currently limited by the network I think) but I think it is worth mentioning that we have a prototypic implementation in FPGA and a ground implementation in software
  *   We need to create a new project for the orange book.
Slide 5: for the previously-planned work items: maybe it is worth to mention ‘CCSDS Delivery Agent (First-Hop / Last-Hop services)’ to start making other areas aware)

Regards,
Felix

Hi Bob, all,

I indeed acknowledge it has been a very intense and fruitful CCSDS DTN meeting! Many thanks to all of you for the very good discussions!

As to the prepared slides, the are very detailed and complete, probably I’ll make some statements more coincise as I have a short slot to present all SIS WGs.

Just some requests/clarifications:

1) I need in any case updated dates for the active projects. As mentioned in the chat yesterday probably BPv7 and BPsec could be approved for publication around Spring 2024. The orange CBR possibly already Q1-2024. All the others I guess later, maybe end 2024?
2) for the future projects I understand the plan is to have only orange books for HTP (Hooke is for Adrian Hooke?) and multi-destination, I.e. all other current drafts should disappear, isn’t it? In any case for these draft projects I need estimated dates for start and end. Typically for orange book 1-year duration is ok.
3) resolutions: they can be issued only when corresponding material/content is ready, I.e. BPsec book ready for agency review. As such all proposed resolutions are for the near future, not of immediate execution. For the creation of the planned future orange book project we can iterate during next week. I can tell you already we need start/end, description, agency in charge of editing the book.

Best,

Tomaso

I neglected to mention the resolution to reaffirm LTP with the corrigendum that is under review within the WG.  I added that, along with the WG motto for the week:  “Orange is the New Blue.”  (Depending on the sense of humor of the CESG, you may want to strike that remark, which is at the top of slide 2…

Best,
Bob

Tomaso,

Thanks to the members of the SIS-DTN WG for what I consider to be an enormously productive meeting, and thanks especially for helping me to get up to speed as WG chair.

Attached please find the SIS-DTN report for incorporation into your SIS report to the CESG.  Apologies for the length, but there is much to report and update.

The key resolutions coming out of this meeting are as follows:
1.       Submit BPSec for Agency Review
2.       Charter DTN Multi-Destination Orange Book work item

Do you formulate those resolutions or do we?  What is needed to charter the DTN Multi-Destination (aka, but don’t call it, multicast)?  If I need to formulate those resolutions, by when do you need them?  (And can you point me toward a somewhat current example?)

You will note that we have had to be rather ruthless in deferring or eliminating work items that do not seem feasible to complete in the context of the needs and need dates we identified during our review of mission capability needs.  If these need further explanation/rationale, please let me know.

If you have any questions, please call me at +1 703-217-7414.  I will be flying between about 8am and noon CDT tomorrow (Saturday).

Thanks and best regards,
Bob
