[SIS-CFDPV1] CFDP WG (Virtual) Meeting

[구철회]

Hi Felix, Can we discuss about what the future direction of CFDP revision would be?
Also, can we think about the possibility of much lighter version of CFDP Class 1 like tftp (Trivial FTP)?

I think much of functions in current CFDP are being done by LTP convergence layer. CFDP is very capable of handling file delivery service for which LTP/BP is not considered, but when and where LTP/BP are involved I feel most functions in CFDP redundancy because similar functions are already provided by LTP layer. I think it may be enough if CFDP has some critical functions without listing of Metadata/Fdu/NAK/EOF/FIN PDUs, e.g., file name, file length, NAK, cancel, file creation/deletion/change and so on, like TFTP.

I am just curious to know how other people think about this.

Dear All,

first, let's see whether this mailing list is still active ...

It has been very quiet at CCSDS since the publishing of the B5 version. However, I assume that a lot of agencies have been busy bringing CFDP into their missions. At least I have received some feedback from ESA missions I would like to share and discuss with the WG (eg, introduction of an Abandon.Request; how to react to NAK for unknown transactions; some clarifications). If there is interest, I can also provide some updates related the planned Return CFDP PDU Cross-Support Transfer Service Orange Book which we need to support Distributed CFDP scenarios.

If you have other topics to discuss, please let me know.

I have set-up a doodle poll in order to find a suitable time for a meeting:

Please enter your availability until 28 April.

Regards,
Felix
