<p class="MsoNormal" style="word-break:break-hangul"><span lang="EN-US" style="font-size:10.0pt;font-family:"¸¼Àº °íµñ"">Also, can we think about the possibility of much lighter version of CFDP Class 1 like tftp (Trivial FTP)?<o:p></o:p></span></p>

<p class="MsoNormal" style="word-break:break-hangul"><span lang="EN-US" style="font-size:10.0pt;font-family:"¸¼Àº °íµñ"">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.<o:p></o:p></span></p>

</span><span lang="EN-US" style="font-size:10.0pt;font-family:"Arial",sans-serif">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.
