[SIS-CFDPV1] CCSDS CFDP WG Meeting - Summary

[Felix Flentge]

Dear All,

We have had a short but productive meetings. Here's a short summary:

  *   There is an intention to finish up the remaining activities of the WG (i.e., finalisation of CFDP B6 Blue Book) asap (~ Fall 2026) and then put the group into a dormant state
  *   The UT Layer Magenta Book has been finalised, all RIDs responded and Tomaso will initiate CESG poll for publication
  *   We want once more through the CFDP B6 draft which is essentially ready. Two minor changes/additions have been agreed:
     *   Handling of cases where one side is requesting or sending Keep-Alive PDU but the other side is not supporting needs to be addressed (Unsupported Feature Fault)
     *   Introduction of a new condition code 'protocol error' which should be included in an EOF (cancel) in all cases where an implementation cannot parse a received PDU (like a not supported CFDP version or a malformed PDU)
  *   ESA will perform these and a couple of editorial changes and submit then the book to initiate agency review
  *   ESA / NASA MSFC (ie Josh) will implement the changes; ESA will provide a detailed list of all the required changes to its current B5 version and the related test cases; these can be used as a basis for the yellow book
  *   Yellow book creation / interoperability testing is expected to start Q1/2026

Regards,
Felix
