[cssm] [EXTERNAL] CSSM: Service Agreement Parameters - Update of the presentation from Fall Meetings 2023

[Shames, Peter M (US 312B)]

Hi Marcin, et al,

It’s great that you guys have started to develop this Service Agreement framework.  I think it should be of a lot of use and that what you have produced is a good start.

That said, I have a few comments and observations that will undoubtedly come up when this standard crosses my desk as part of a CESG review.  So I thought I’d toss them out now, for your consideration.

Comments

  1.  This draft makes mention of a variety of objects for which we have existing (if somewhat incompletely filled out) SANA registries, but there is no mention of SANA anywhere.  I believe that all of the following should be referenced, and that the standard should clarify how these are to be used, extended if needed, or substituted only where it is essential to do so.
     *   https://sanaregistry.org/r/organizations/
     *   https://sanaregistry.org/r/contacts/
     *   https://sanaregistry.org/r/service_management_entity_types/
     *   https://sanaregistry.org/r/service_sites_apertures/
     *   https://sanaregistry.org/r/spacecraft/
     *   https://sanaregistry.org/r/spacecraftid/



  1.  This seems to be exclusively focused on “standard” Earth to S/C services, but we are already in an era where there are existing “space based services”, like the Mars orbiting missions, and the Lunar mission set, with “standardized” relay operations, is already in development.  Is there a plan for addressing these other classes of missions?
  2.  Is there a plan to build in extensibility for new service types as these are developed?  This might include, for instance, Lunar PNT services, DTN services, and DTN to IP “protocol bridging”.

I’d be happy to discuss this at more length when you are ready.

Thanks, Peter

Subject: [EXTERNAL] [cssm] CSSM: Service Agreement Parameters - Update of the presentation from Fall Meetings 2023

Dear all,

I had a small task to update the collection of the Service Agreement parameters, which I presented during Fall Meetings 2023. During this presentation we had a discussion and number of comments/changes, which now I implemented. As you can see I still have there two or so “TBCs”. Except that I think it looks good for the first schema version for SA File type. I will try to set it up until our next teleconference, but not promising it….;-)

Cheers
Marcin
