<span style=" font-size:10pt;font-family:sans-serif">(Sorry, if you already
received this. CCSDS mailman didn't seem to like my original message.)</span>
<br>
<br><span style=" font-size:10pt;font-family:sans-serif">Dear All,</span>
<br>
<br><span style=" font-size:10pt;font-family:sans-serif">thanks for the
detailed input to the CCSDS BPv7 discussions.</span>
<br>
<br><span style=" font-size:10pt;font-family:sans-serif">CLA:</span>
<br><span style=" font-size:10pt;font-family:sans-serif">- I would also
add CLA for space and encapsulation packets as necessary CLA</span>
<br>
<br><span style=" font-size:10pt;font-family:sans-serif">DTCP:</span>
<br><span style=" font-size:10pt;font-family:sans-serif">- The current
transport service guarantees in-sequence, reliable delivery without duplications.
I think it would also make sense to have reliable delivery without the
in-sequence / no duplication option.</span>
<br><span style=" font-size:10pt;font-family:sans-serif">- In order to
get CCSDS BPv7 out quickly, it might make sense to have a separate book
for DTCP.</span>
<br>
<br><span style=" font-size:10pt;font-family:sans-serif">ACS:</span>
<br><span style=" font-size:10pt;font-family:sans-serif">- We have started
working on a 'compressed bundle reporting mechanism' which could be used
as a more generic alternative. It does not rely on timers but on applications
receiving signals about bundle reception/deletion/forwarding/delivery.
Re-transmission of bundles could be requested from an application by an
explicit command. I am happy to introduce the initial concept in one of
the next WG meetings.</span>
<br><span style=" font-size:10pt;font-family:sans-serif">- BIBE is not
a full replacement for the current custody transfer as the sender has to
address the BIBE endpoint explicitly and intermediate nodes cannot accept
custody. It might be possible to overcome this limitation using non-singleton
endpoints. However, the current BIBE draft does only allow singleton endpoints
if Custody Transfer is used. I am still not sure whether this limitation
is necessary.</span>
<br>
<br><span style=" font-size:10pt;font-family:sans-serif">Self-identification:</span>
<br><span style=" font-size:10pt;font-family:sans-serif">- I would assume
that the use of the previous hop extension block (or other extension blocks)
would be governed by a 'network policy'. IMHO, the use of these blocks
should be optional in the standard.</span>
<br>
<br><span style=" font-size:10pt;font-family:sans-serif">BBSP:</span>
<br><span style=" font-size:10pt;font-family:sans-serif">- Again, in order
to get CCSDS BPv7 out more quickly, I would vote for a separate book.</span>
<br>
<br><span style=" font-size:10pt;font-family:sans-serif">Regards,</span>
