(Sorry, if you already received this. CCSDS mailman didn't seem to like my 
original message.)

Dear All,

thanks for the detailed input to the CCSDS BPv7 discussions.

CLA:
- I would also add CLA for space and encapsulation packets as necessary 
CLA

DTCP:
- 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.
- In order to get CCSDS BPv7 out quickly, it might make sense to have a 
separate book for DTCP.

ACS:
- 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.
- 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.

Self-identification:
- 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.

BBSP:
- Again, in order to get CCSDS BPv7 out more quickly, I would vote for a 
separate book.

Regards,
Felix

Good morning all,

Attached are BPv7 Red Book Discussion Topics from MSFC. We (MSFC) provide 
our opinions on how the topics listed within should be managed. Please 
provide your input via email on these topics so that we may take them into 
account as we write sections for the BPv7 book. If we run into a 
discussion that isn?t resolving over email, we will resolve in the SIS-DTN 
forum.

Regards,

Beau Blanding

When: Wednesday, August 11, 2021 11:00 AM-12:00 PM (UTC-05:00) Eastern 
Time (US & Canada).
Where: Microsoft Teams Meeting

20210407 ? Just refreshing the calendar invite in case it got dropped 
somewhere.

Folks,

I?d like to set up some recurring SIS-DTN meetings to talk about our 
current work items.  I?ve set these for every 2 weeks; if it looks like we 
don?t need to meet that often I?ll drop it down to monthly.

I?m proposing Wednesdays 11am; I get that this time won?t work for 
everyone, but let?s see how many can make it and if we have to we?ll hunt 
for a different time.

                                v/r,

                                --keith
