Hi Peter,
                   afraid I can't make any of the suggested dates. For me 
the week after would be better.

Cheers for now,

Subject:        Request for a brief coordination meeting on SCCS-ARD 
planned changes

Dear SLS, CSS, SIS, and SEA colleagues,
In the SEA Systems Architecture WG (SAWG) we are working on a revision of 
the Space Communication Cross Support Architecture Requirements Document 
(CCSDS SCCS-ARD, 901.1-M-1).  That document presently describes how more 
than fifty-seven (57) normative CCSDS standards may be fitted together, 
like some giant jig-saw puzzle, to mee the needs of users who design and 
build flight and ground communications assets.  In the time since that 
standard was published a number of these normative standards have been 
updated, some with new features, and a significant number of new standards 
have been published, especially in SLS and CSS, but also in SEA itself.
We have identified some issues with the current document structure that 
requires changes to the chapters for clarity of presentation.  We have 
also identified some complexities introduced by new standards, such as 
USLP, optical comm, VCM, and newer security features that are driving a 
change in approach.  And we are adding all of the new standards that have 
been introduced since this document was published.
We would like to present these issues and how we plan to  address them to 
whichever members of your teams would be willing to participate.  This is 
an unusual request for a WG, which usually do this sort of work behind 
closed doors, but since this document cross cuts all of your WGs we 
thought it useful and, we hope, valuable to you.  Since we have focused on 
ABA deployments the only Area that is not directly affected yet is SIS. 
That said, you may still wish to see what we are doing to the layers that 
underpin your networking layer standards. 
I?d like to schedule this coordination meeting in the week between the end 
of  the nominal ?working meetings? and the CESG /CMC meetings.  That would 
be the week starting 1 June.  Please go to this Doodle poll and indicate 
your availability.  Please feel free to invite your WG chairs, and 
whichever other members of your WGs, you think would be willing to 
Replies, please, by CoB, Friday, 7 May 2021.
Thanks, Peter
