[Css-csts] updated MD-CSTS on CWE

Wed Jul 8 14:15:16 UTC 2015

Dear Margherita,
I think that getting the registry established, even though it’s final content is not “perfect”, is an excellent idea.

Regarding the ‘controllable’ field, I suggest that we use the term “configurable” for the field (attribute). “Controllable” has the connotation of real-time control, i.e., being able to be changed during the execution of the service package. All configurable attributes have to be declared by CCSDS (they are what have to be managed in order for the functional resource to operate properly). All configurable parameters are also candidates for being controllable, but each Agency/Complex/Provider CSSS will have to decide which subset of those configurable parameters (if any)  it actually allows to be changed during service package execution (or as part of an Event Sequence).

As far as the future Service Control CSTS is concerned, all configurable parameters will be potentially changeable, but if an Agency/Complex/Provider CSSS does not support real-time control of a given parameter an EXECUTE-DIRECTIVE invocation to change the value of that parameter would fail with an ‘invalid Functional Resource parameter’ diagnostic.

Best regards,
John

Dear John,
many thanks for this update.
Concerning the URL of  the SANA Registry of Functional Resources, I was thinking of contacting the SANA engineer, in order to "move" our beta version to the final destination in the Registry. In fact, although the FR table needs to be reworked to a certain extent, I think the prototyped version meets our expectation about the shape of the registered items.
In this way, at least the URL can be definitively established - and possibly before the MD CSTS gets finally to the top of the editor's queue ( and so, we may have this last-minute change done by the editor).
As to the work required to complete the content of the registration, I will address that with Wolfgang and Holger. Basically, I think we need to add one field to the parameter's entry, to state if the parameter is controllable, and , most demanding, we need to bring the FRs, parameters and events in line with the last version of the FR/parameter  model.

With this version of  MD CSTS I think the implementers of the Prototype (CNES and ESA) can start looking into the changes with respect to the old  version of the the prototype. Then, the actual implementation can start only when the Framework API will be completed (hopefully by end of September).

Kind regards,
Margherita

CSTSWG colleagues ---
I have uploaded an updated version (R-1.4) of the MD-CSTS to the CWE> Cross Support Services Area (CSS)<http://cwe.ccsds.org/css> > Documents<http://cwe.ccsds.org/css/docs/Forms/AllItems.aspx?View=%7B8045374D-F8E0-4356-83CA-993252A38FE8%7D> > CSS-CSTS<http://cwe.ccsds.org/css/docs/Forms/AllItems.aspx?RootFolder=%2Fcss%2Fdocs%2FCSS%2DCSTS&View=%7B8045374D-F8E0-4356-83CA-993252A38FE8%7D> > CWE Private<http://cwe.ccsds.org/css/docs/Forms/AllItems.aspx?RootFolder=%2Fcss%2Fdocs%2FCSS%2DCSTS%2FCWE%20Private&View=%7B8045374D-F8E0-4356-83CA-993252A38FE8%7D> > 2 - MD CSTS RED-1 Review material folder at URL
http://cwe.ccsds.org/css/docs/CSS-CSTS/CWE%20Private/2%20-%20MD%20CSTS%20RED-1%20Review%20material/MD-CSTS-922x1r1_4.zip.zip

The updates reflect the outcome of the discussion of the MD-CSTS during the CSTSWG WebEx on 24 June 2015. Specifically:

1.       A reference ([3]) to the “SANA Functional Resources registry: TBD” has been added to the References section (1.10), and references to that SANA registry throughout the book now point to reference [3].

2.       Wording has been added to Annex F, Example Functional Resource Type Object Identifier Registry, explaining that the parameter attributes in annex F are the subset of the SANA registry parameter attributes that are most useful in understanding the Operational Scenario in 2.5.

With these updates the book is as complete and correct as possible until the time that the SANA FR registry is established, at which time the “TBD” of reference [3] can be replaced by the actual URL of the SANA FR registry.

Note that the file that has been uploaded to the CWE is a zip file that contains both the draft Recommended Standard itself and a plain text version of the two MD-CSTS-specific ASN.1 modules. These ASN.1 modules have not changed since the previous version, but I have included them for completeness.

Best regards,
John
