[CESG] RE: Projects for CFDP Blue Book / was: Draft CFDP Pink Sheet supporting an optional 'finished' PDU in class-1

[Scott, Keith L.]

Gian-Paolo,

You are correct, except (as detailed below) I don't think there's a danger of having 'concurrent / possibly conflicting changes' to CFDP.

I think #2 (the pink sheet) can be done way before the due date, as the draft modification includes only a very minor modification of the existing protocol.  My hope is to have the pink sheet out for review within a month or so.  This would allow the pink sheet to be completed before the CFDP update WG gets under way.

Scott provided some draft project material for the CFDP update projects that I've also entered into the CCSDS Update WG Framework.

I don't think there's any danger of concurrent updates / duplication of effort since:

1)    I expect the Pink Sheet to be done before the CFDP Update WG gets well under-way

2)    The community of interested parties is small enough that the Pink Sheet material, even if not completed by the time the CFDP update WG gets going, can easily be made known to the CFDP update WG.

Keith,
        let me understand the situation.

1) The latest version of the CFDP Blue Book is Issue 4 dated January 2007 (see http://public.ccsds.org/publications/archive/727x0b4.pdf )
2) SIS-DTN is currently running a project titled "CFDP-over-BP Pink Sheet" for producing Issue 5 of the  CFDP Blue Book.
See http://cwe.ccsds.org/fm/Lists/Projects/DispForm.aspx?ID=199
This project is supposed to finish the work in August 2014.
3) It is proposed to create (resurrect) a SIS-CFDP WG to "accomplish the mandated 5-year reconfirmation review of the CCSDS File Delivery Protocol (CFDP) Blue Book"; i.e. to work on  CFDP Blue Book Issue 4.
4) The SIS-CFDP has currently no linked/proposed CWE Project so it is not possible to know when it will start work and will it will finish it (e.g. in parallel with SIS-DTN or after SIS-DTN issues CFDO #5?). ==> A CWE project linked to SIS-CFDP shall be created also to allow CMC to approve relevant resource needs.

It appears to me that with this situation we have a chance of having two WGs working on the same issue of the book (i.e. issue 4) unless SIS-CFDP will wait for Issue 5 being finalized bu SIS-DTN.

Sorry, but I am just puzzled.
Can you shed some more light?

Gian Paolo
