By the way, a related technical detail to take care of in Boulder:

The linkage for communicating a peer-abort from one Provider state table to another appears to be incorrect in the current Framework spec.

For example, the Buffered Data Delivery procedure communicates a peer-abort by raising the 'Peer-abort invocation' to the Association Control procedure.  But a 'Peer-abort invocation' event is associated with an incoming peer-abort invocation from the CSTS *partner*.  The correct linkage for *internal* propagation of a peer-abort is by raising the 'Peer-abort xxx' event in the Association Control procedure.

Best regards,
Tim

Subject: User state table for "startable" procedures

Hi,

I've uploaded state table logic for the User side of "startable" Framework procedures:

http://cwe.ccsds.org/css/docs/CSS-CSTS/CWE%20Private/CSTS%20Framework%20and%20Concept/2011_24_October%20Stateful%20Procedure%20User%20State%20Table.doc
The bigger picture:
The Framework spec has state tables for the *Provider* side of all Framework procedures.  A state table for the *User* side of the Association Control procedure was uploaded months ago:

http://cwe.ccsds.org/css/docs/CSS-CSTS/CWE%20Private/CSTS%20Framework%20and%20Concept/2011_25_May%20Assoc%20Control%20User%20State%20Table.doc
The Association Control state table covers the Bind/Unbind logic.  Today's upload covers the Start/Stop logic that is the heart of most of the other procedures.  If there is a consensus that it would be better to publish a separate User state table for each Framework procedure (i.e. 8 User state tables instead of 2),  I would be willing to put that together.

The User-side logic for the Data Processing is a superset of today's upload, so it makes sense to add one more User state table to cover this procedure.  Because the Data Processing procedure is still in flux, I would like to hold off on developing this state table.  However, if anyone responds saying "please provide a 'Data Processing' User state table for discussion in Boulder", I will attempt to do so.

Best regards,
Tim
