[SIS-CFDPV1] updated CFDP Revisions draft

[Jeremy.Mayer at dlr.de]

Hey,
Everything looks fine from my side, except for one not-so-minor issue: The checksum type ID field is 6 bits long, but has been outlined in the proposed registry as an 1-byte value, and we have (tentatively) reserved 0xFF as the NULL checksum. Therefore, the metadata PDU cannot unambiguously define data which is using the NULL checksum.

Thanks,
Jeremy

Subject: updated CFDP Revisions draft

Hi, all.  I have made all the changes to the revised CFDP Blue Book that I think are needed in order to make the file checksum algorithm selectable by reference to the new SANA checksum algorithm registry.  The updated document is now in CWE at https://cwe.ccsds.org/sis/docs/SIS-CFDPV1/Draft%20Documents/727x0b5%20--%20Specification%20--%20Blue%20Book/727x0p42_working%202.doc?Web=1.  Please take a look at it when you have a moment; I'd like to send a final draft to Tom and ask for a supplementary Agency review soon, maybe as early as next month.

Scott
