Hi Felix,
<div><br>
</div>
<div>As to your first observation, this is indeed the result of the process we started a few years ago. At that time we are all on the same page that we needed to update the BPv6 book in order to have the BPv7 as new issue of that one, thus implying that BPv6
would have been silverised. Because of that, we started pink sheets.</div>
<div> If on the contrary we wanted to have BPv7 book and also keep BPv6, we should have started a new project, without claiming this to be an update of BPv6 book. In such a case we would have had the red book.</div>
<div>For BPsec, it was slightly different because we had first an agency review of the once called streamlined security BP and then we decided later to “trash” it and restart with BPsec. Tom suggested to have this as an evolution of that initial red book and
having a second agency review, though formally was an exception. In any case it is about a new book, I.e. no update of an existing book, hence red instead of pink.</div>
<div><br>
</div>
<div>In any case I concur that we have to agree on the next steps as soon as possible so that we have a plan before end of April and I see how to solve this situation with Tom and CESG, if the case.</div>

<p class="MsoNormal" style="margin-left:36.0pt">Concerning Leigh’s point, as soon as BPv7 book will be published as 734.2-B-2, the previous release I.e. BPv6 will become silver (I.e, obsoleted and maintained as historical record).
<o:p></o:p></p>
<div>
<p class="MsoNormal" style="margin-left:36.0pt">If I’m not wrong we took this path exactly because we wanted CCSDS to go on only with BPv7 and “forget” about v6. Now if on the contrary it turns out that we would like instead to keep both, maybe v6 for not that
long I’ll check with Tom how to handle this situation. I’d expect that we could have a new number for v7 and issue a corrigendum for the title of v6 book.<o:p></o:p></p>

<p class="MsoNormal" style="margin-left:108.0pt">I wish to note that while BPv6 is, I assume, deprecated (where does it say that in any CCSDS docs, by the way?), we still have missions and users flying BPv6, and in the future
<u>continued support for bpv6 is required.</u><o:p></o:p></p>

<p class="MsoNormal" style="margin-left:108.0pt">If a user wishes to write a new application that is designed for BPv6, do we put in the contract to write something that is compatible with BP as specified by 734.2-B-1 (which does not indicate any particular
version of BP in its title), and then on another project using BPv7 specify 734.2-P-1.1 (which has the same title as 734.2-B-1)?? Do you seriously think that won’t be confusing??<o:p></o:p></p>
<p class="MsoNormal" style="margin-left:108.0pt"> <o:p></o:p></p>
<p class="MsoNormal" style="margin-left:108.0pt">If you are going to change a protocol in such a dramatic manner as to completely eliminate backward compatibility, from a System Engineering point of view, and as one who has to help both projects and the DSN
do the formal documentation of what service agreements are with external customers, I believe CCSDS is making a bad mistake not giving the Bluebooks SEPARATE numbers and titles that indicate that the specification is for a particular protocol that is totally
incompatible with another protocol with the same CCSDS book name.<o:p></o:p></p>
<p class="MsoNormal" style="margin-left:108.0pt"> <o:p></o:p></p>
<p class="MsoNormal" style="margin-left:108.0pt">The recommendation is therefore to Change the title of the current BPv7 draft specification to “CCSDS BUNDLE PROTOCOL v7 SPECIFICATION”, assign it a new and non-confusing CCSDS book number, and then to add to
the title of the existing 2015 BPv6 734.2-B-1 the indication that it is for BPv6.<o:p></o:p></p>

</span>What is the IETF posture on BPv6 (RFC 5050)? It is listed as an experimental protocol, while RFC9171 is “standards track,” but not yet an internet standard. There is no attempt in the IETF to maintain backward compatibility, because nothing in the
IETF world is using BPv6 operationally, unlike the CCSDS world.<o:p></o:p></p>
