[CMC] CMC Poll Results and Dispositions - AMS

[Soula Jean-Marc]

Dear all,

I'm a bit late with my answer but I hope it is still Febr 06 somewhere in the world, even if it is already Febr 07 in my place...

On Dispostion CNES1, after consulting with my colleagues in the M&C, we couldn't find an evidence in the minutes and reports that all RIDS made on the AMS had been answered and in particular the one on the parallel agency reviews. Nonetheless, the general impression was that an agreement was more or less reached. However, it remains a concern that the agency reviews may not produce consistent results and that the AMS and SM&C layers are not fully compatible. In that respect, the fact that the AMS prototyping was not yet completed gives an opportunity for the AMS WG to demonstrate their compatibility at the time of their prototyping. This could be a way to clear CNES provisions if acceptable on the AMS WG side, possibly after a verification on with the SM&C WG.

Best regards

Dear CMC members,

The Agencies that provided comments to the e-poll are 
requested to please review the dispositions stated below. 
 If no disagreements to the dispostions are received by 6 
February, then the Secretariat will proceed with the 
release of the document for Agency review.

*********

CMC E-Poll Identifier:  CMC-P-2007-01-002: Authorization 
to approve Asynchronous Message Service (AMS) for Agency 
review

Results of CMC poll beginning 9 January 2007 and ending 31 
January 2007:

                 ADOPT:  5 (50%) (ASI, CSA, INPE, NASA)
   ADOPT PROVISIONALLY:  4 (50%) (BNSC, CNES, DLR, JAXA)
                REJECT:  0 (0%)
  REJECT WITH COMMENTS:  0 (0%)

      BNSC:  Also agree with comments from DLR

DISPOSITION [BNSC]:  See DISPOSITION [DLR], below.

      CNES:  Two questions in fact for clarification 
before the Agency Review:
- 1 - Which two prototypings were realized to consolidate 
this Red-1 version of the AMS ?

- 2 - Isn't it worth waiting till the Red-1 version of the 
"Messaging Abstraction Layer" (MOIMS/SM&C) is also ready 
for agency review, so that both recommendations which have 
obvious interfaces between them, are jointly reviewed 
across the agencies ?

DISPOSITION [CNES1]:  Prototype implementations are 
required prior to release of Blue Books.  No such 
requirement holds for Red Books.

DISPOSITION [CNES2]:  The AMS and SM&C WGs have agreed on 
an approach with which the added value of parallel review 
does not appear to justify delay of the AMS Red-1 review 
(see DISPOSITION [DLR], below).

      DLR:  The agency review should wait the decision of 
the colorado meeting. Most of the rids are said to be 
clarified there. It makes no sense to ignore the 
dispositions of the currently available RIDs and start 
already the agency review.

DISPOSITION [DLR]:  In discussions between AMS and SM&C 
WGs in Colorado Springs, agreement was reached on the 
following approach: to define multiple approved SM&C 
protocol stack profiles in a series of magenta books, not 
all of which would mandate AMS.

      JAXA:  JAXA agrees with DLR

DISPOSITION [JAXA]:  See DISPOSITION [DLR], above.

Results are based on responses from 8 out of 10 members 
(80%).

No response was received from the following Agencies:

ESA
FSA

Secretariat Interpretation of Results:  Adopted 
Provisionally
Resulting CMC Resolution:               TBD
Inferred Secretariat Action:            Release Review 
Document
