Hi Howie,

I think that for this note it is sufficient to point to a single book, then the reader can check also the other books if the case 😉 As such, I’d stay with either the blue or the green. I let the WG to decide which one they would like to go for.

Regards,

Tomaso

Or for completeness, just reference both the SDLS Blue and Green Books (one stop shoping for the reader).

Thanks, Tomaso.  I think referencing the green book makes sense, as this recommendation is not normative upon LTP; the LTP implementer who wants to use SDLS will be able to navigate from the green book to the blue book.

Thank you Keith & Scott for the great work in editing the annex.

There are still a few remaining comments in Sections 3.9 and 3.10, which however are pretty much about formatting and I can fix them myself. In particular in Section 3.9, we have the following note, where we forgot to add the reference to SDLS documents:

Since this specification was published, new security mechanisms have emerged or are being developed and standardized in CCSDS for the data link layer (reference SDLS – informative reference?) and the bundle layer (BPSec). Implementors may want to omit LTP security in favor of the newer capabilities.

My idea here would be to refer to the SDLS green book and to add it to the list of informative references:

CCSDS 350.5-G-2             Space Data Link Security Protocol—Summary of Concept and Rationale

Please let me know if you prefer to use a different reference, e.g., the SDLS blue book.

Regards,

Tomaso

LTP Corrigendum

We took out the 'shall' language and replaced it with requests or affirmative language.

We removed 'node' and the sort of implicit linkage to RASDS and used an engine ID POC (EPOC instead of NPOC).
