[Css-csts] CSTS WG - Draft Minutes of Pasadena meetings

Tue Mar 31 23:00:59 UTC 2015

Dear Margherita, Tim and all,
Please find attached the test results from Pasadena. The testing went well with a few issues identified that we believe are implementation issues and not specification issues. I have done some research since returning home and have summarized my findings below for the failure conditions. Hopefully, we can correct these issues and arrange to retest them remotely.

I added a section 1.1 Preliminary Testing Comments to detail the issues discovered in the preliminary testing.

The 4 tests which had failure conditions are in red in the document and a summary follows:

3.8 COMPLETE MODE - SERVICE INTERRUPTION NOTIFICATION
* The Provider prototype failed to send an 'operational' notification in step h) when production was re-started
** An error was found in the Provider prototype source code

4.8 PROCESS-DATA INVOCATION RECEIVED WHILE INTERRUPTED
** Test procedure was incorrect. The intent was for the Provider to generate a negative return indicating 'unable to comply' which happens when the User issues a START Invocation while production is interrupted. The test procedure incorrectly had the negative return associated with the PROCESS-DATA Invocation.

4.11 CLEAR LOCKED STATE WITH RESET EXECUTE-DIRECTIVE
* User prototype timed out waiting for the Reset Execute-Directive Acknowledgement or Return?.
** Additional testing with the Provider Prototype indicates that the Execute-Directive Acknowledgement does get sent properly. Did the User prototype time out waiting for the Acknowledgement or the Return? There should not be a time limit on the Return.

4.15 DATA UNIT ID WRAP AROUND
* User prototype sent large Data Unit ID as a negative number     (the ASN.1 issue that Tim mentioned)
** An error was found in the User prototype source code

Best regards,
DZ

Hi Margherita,

I have no objections to the action items that are "propose to close".

The work plan looks good.

The proposed teleconference dates are ok for me.

One comment on section 11 of the Meeting Minutes (Prototypes):
The first comment says that the outcome of the on-site testing at CalTech is "all test procedures have been run flawless".  While the testing did go very well, there was one test that failed due to an ASN.1 decoding failure.

Best regards,
Tim

Dear All,

The draft MoM of the Spring Meetings is available on the CWE,  under Meeting Materials/2015 Spring Pasadena.
Please do take a look at it and let me have your comments. Particularly, I would like to draw your attention on:
1)        Action Items from previous meetings:  for a couple of Actions I've put "propose to close", and a description is added in blue text below the Action itself. Please let me know if you have any objection to the closure
2)        Please check the Workplan. There, I have put the person in charge of each activity, but no dates. Some dates, relevant to the completion of books editing, have been put in the table about "WG Products" .  Everything else is based on best effort.
3)        Please check the proposed dates for the Teleconferences, and let me know if you have any issue with that.
Looking forward to receiving your feedback, kind regards,
Margherita
