[Sis-dtn] DTN Reference Scenarios

[Tomaso.deCola at dlr.de]

Hi Felix,

thank you for sharing the slides presented yesterday.

Just three comments:


  1.  I see no mention of optical communications, while the lunar WG within IOAG was pointing to them too. Any reason for excluding them now from the picture?
  2.  The SOIS-WIR WG has been working on green and blue books about the communication solutions for in-situ planetary network, possibly resulting in the coexistence of 3GPP/WiFi solutions with DTN-based ones. Is this also captured in the pictures you have put in your slides?
  3.  As to where push information about all (and possibly other) DTN reference scenarios, let's not forget that we have the CCSDS 734.0-G-1 "Rationale, Scenarios, and Requirements for DTN in Space" which is since long (the document was published already in 2010) in our ToDo list for the 5-year review. Probably the material you provided in the slides could be further elaborated and expanded for a new version of that green book. In any case it is probably now time to think how and when to start the 5-year review of that book (I know all our resources are on the blue and orange books, but that green book is really old and must be refreshed)

Just another point somehow correlated to scenarios: during the monthly telco between SIS and IETF DTN WG, it emerged that IETF would like to come up with a concept/white paper about the challenges of space internetworking. Moreover, a first step would be to review and update RFC4838 which now contains some outdated content that should be revised. I add here Ed who can say a few words more on this point.

Regards,

Tomaso

Dear All,

I have uploaded today's presentation on DTN Reference Scenarios to CWE:

https://cwe.ccsds.org/sis/docs/SIS-DTN/Other%20Documents/DTN%20Reference%20Scenario/CCSDS%20DTN%20Scenarios.pptx?d=wf3b24c8d83344cf998bc7846fe279269

Please let us know if you have any feedback (in particular, on the overall topologies - we need to fix them now for the next steps).

Regards,
Felix
