Dear CCSDS AD and WG chairs,

The review of the SCCS-ARD has been scheduled for Tuesday, 23 Nov, 2021 at 
0700 AM PST.  The draft of the document, which is in rough, “track 
changes”, form is available on-line.  The proposed updates to the ABA 
subsections of sections 4, 5, and 6 (except for the security-specific 
subsections) and posted the draft to the CWE at:

https://cwe.ccsds.org/sea/docs/SEA-SA/Draft%20Documents/SCCS-ARD-ADD%20Revisions%202020/SCCS-ARD%20draft%20documents/SCCS-ARD-901x1p1_10-211108.doc?d=wd389d0c8026d47a591fbc35f2e261b58

Feel free to download this and review the sections that are of interest 
most interest to you (or all of it if you wish).  If there are members of 
your WG who can usefully contribute to this review please feel free to 
invite them as well.

The Space Communications Cross Support Architecture document (SCCS-ARD) is 
a cross-cutting Magenta Book that largely covers the SLS, SIS, CSS, and 
SEA areas and their working groups.  We have being working on an update to 
this document that primarily covers what are called “ABA” mission 
configurations, which are those that involve a single mission ops center, 
a single spacecraft, and a ground station.  The Solar System Internet 
(SSI) configurations, which involve multiple spacecraft, mission centers, 
and comm assets, and use the DTN (or IP) protocols, will be in a future 
update that builds on this foundation.

There have been a number of changes to the CCSDS standards landscape since 
the last edition was published.  These include:

USLP protocol
The “VCM suite” of variable coding and modulation standards
New CSTS services
New Service Management standards
Updates to the Synch and Channel coding specs, the liberal approaches
New security features in several sections

In addition to these new / updated standards we wish to address the 
following issues as well:

Improved handling of cross references from the Services viewpoint to the 
protocol stack details (interface binding signatures)
Revised section structures and cross referencing
Inclusion of “recommended” options and clarification of optional and 
mandatory features
Discussion of incomplete / optional capabilities like forward file 
service, handling of details of complexities like MAP service and VC/MC 
multiplexing, COP on the USLP return link, and CADUs in FF-CSTS given new 
Pseudo-randomized “Only Idle Data” (OID) frames

Hope to see you at this review.

Thanks, Peter Shames & John Pietras
