<p>Hi,</p>
<p>What do you mean by distributed CFDP? In the sense of cross-station CFDP support with associated buffering?
<br>
</p>

<p>Thanks,</p>

<div><span style=" font-size:10pt;font-family:sans-serif">Dear Scott,</span> <br>
<br>
<span style=" font-size:10pt;font-family:sans-serif">I agree with your proposal to keep the WG in hibernation.</span>
<br>
<br>
<span style=" font-size:10pt;font-family:sans-serif">Regarding a virtual meeting, we have conducted some internal work on a "Distributed CFDP Concept" to cover the needs of our upcoming Earth Observation missions with very high downlink rates. While we currently
believe that this concept does not (necessarily) require changes to the CFDP standard itself, it might be interesting to present the concept to the working group.</span>
<br>
<br>
<span style=" font-size:10pt;font-family:sans-serif">Actually, we aim at standardising a Return CFDP PDU Cross-Support Service to support this concept. This would be under the responsibility of the CSTS WG where Holger Dreihahn already presented the concept
during the last meeting. Nevertheless, it is of course important, to define this service in close collaboration with the CFDP WG (if there is interest).</span>
<br>
<br>
<span style=" font-size:10pt;font-family:sans-serif">Regards,</span> <br>

<p style="margin-top:0px;margin-Bottom:0px"><span style=" font-size:11pt;font-family:Calibri">Hi, all. With the CCSDS fall meetings coming up soon, I would like us to reach some consensus on next steps for the CFDP Revisions Working Group. Because all items
of the WG’s Charter have been completed, I don’t plan to schedule a virtual meeting of the WG next month; the only question on the table, I think, is whether to terminate the WG at this point or instead to place it in a “dormant” (hibernation) state, much
like the Voice WG.</span></p>
<p style="margin-top:0px;margin-Bottom:0px"><span style=" font-size:11pt;font-family:Calibri"> </span></p>
<p style="margin-top:0px;margin-Bottom:0px"><span style=" font-size:11pt;font-family:Calibri">The SIS WG chairs agree that the latter is preferable: more work on CFDP will become necessary at some point in the future, and the administrative procedures for starting
up a new working group are time-consuming. Resuming the operations of a dormant WG to address new issues is vastly easier.</span></p>
<p style="margin-top:0px;margin-Bottom:0px"><span style=" font-size:11pt;font-family:Calibri"> </span></p>
<p style="margin-top:0px;margin-Bottom:0px"><span style=" font-size:11pt;font-family:Calibri">But if any of you all believe that the CFDP Revisions Working Group should simply be terminated altogether at this time, please speak up.</span></p>
