<br><font size=3 face="sans-serif">Hi, CFDP fans. The work items
in the charter for the CFDP Revisions Working Group have been completed
(modulo a small amount of Green Book editing I need to do to satisfy publication
poll conditions), so it is just about time to put the Working Group into
hibernation. But Felix raised an interesting point of technical discussion
that I think we might spend some time on during these Fall technical meetings.</font>
<br><font size=3 face="sans-serif"> </font>
<br><font size=3 face="sans-serif">So I am proposing that we meet for 90
minutes at 0700 Pacific time (1000 Eastern, 1500 CET, 2200 CST, 2300 JST)
on Friday, November 6, to discuss ESA’s Distributed CFDP concept. If
anyone finds this time slot impossible, please let me know. Otherwise
I’ll send out some sort of virtual meeting invitation, TBD, when I return
from vacation week after next.</font>

Dear Scott,</font><font size=3 face="sans-serif"> </font><font size=3 face="Arial"><br>
<br>
I agree with your proposal to keep the WG in hibernation.</font><font size=3 face="sans-serif">
</font><font size=3 face="Arial"><br>
<br>
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.</font><font size=3 face="sans-serif"> </font><font size=3 face="Arial"><br>
<br>
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).</font><font size=3 face="sans-serif">

<br><font size=3>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.</font>
<br><font size=3> </font>
<br><font size=3>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.</font>
<br><font size=3> </font>
<br><font size=3>But if any of you all believe that the CFDP Revisions
Working Group should simply be terminated altogether at this time, please
speak up.</font>
