[Scott, Keith L.]

Dear Tech Support,

The CFDP Refresh WG has passed CESG poll with one outstanding item that I am confident we can address.  Can you please place an item in the New Work Item Announcements section:

CFDP Refresh Working Group
The SIS Area has chartered a working group to update/refresh the CFDP specification as required by CCSDS.  The WG charter and list of projects<http://cwe.ccsds.org/fm/Lists/Charters/DispForm.aspx?ID=70&Source=http://cwe.ccsds.org/sis/Lists/Framework/AllItems.aspx> is available on the CWE Framework.  There is a forum<http://cwe.ccsds.org/fm/wiki/Lists/SIS%20Forum/Flat.aspx?RootFolder=%2Ffm%2Fwiki%2FLists%2FSIS%20Forum%2FCFDP%20Updates&FolderCTID=0x012002007973FA855136A4419520DBC51BD46315> on the CCSDS Wiki to discuss the WG, as well as a Wiki page with notes from the Bordeaux Bof<http://cwe.ccsds.org/fm/wiki/SitePages/CFDP%20Update%20Discussion%20Page.aspx> (primarily a list of things that the WG might like to consider as changes to CFDP).

Items to consider for the CFDP update include:

*       Increasing the maximum size of files transferred by CFDP and/or the maximum size of the PDUs used by CFDP

*       Eventually retiring the SFO, Extended Procedures, and Acknowledged Procedures in favor of CFDP / BP (though possibly not in this update)

*       Adding per-segment metadata to increase the value of isolated File Data segments that are received individually

*       Enabling identification of record boundaries in received files.  (Currently record boundaries must be coterminous with segment boundaries, so long records can't be identified.)

*       Identifying the type/format of data (e.g ASCII, EBCDIC, OTHER)

*       Support for compression
