<p style="margin-top:0px;margin-Bottom:0px"><span style=" font-size:11pt;font-family:Calibri">Dear
Erik, Holger, Tom, et al,</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">Please
accept this late input from SEA on this poll. I took the time to
actually review the spec in some detail and it took rather longer than
I expected. I was hoping that this FF-CSTS spec would meet
all of the planned requirements for this forward frame service. Unless
I somehow overlooked some important features that are documented deep in
the bowels of this 218 page specification I am afraid that I have to conclude
that it has missed the mark. </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
“mark” in my understanding, is that this spec was supposed to define
the list of features that follows below. These are drawn from the
original SISG Space Internetworking Strategy report that first defined
the features of this forward frame service intended to accommodate DTN
(and IP) traffic, from the SCCS-ARD/ADD where these features were documented
in the context of the rest of the CCSDS protocol stacks and Earth Space
Link Terminal (ESLT, otherwise known as a ground station plus its associated
control center elements), and the features that already existed in the
EF-CLTU Orange Book that was created because there was no other documented
service for handling the synchronous AOS frame protocol for forward links.</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:10pt;font-family:sans-serif">1.
</span><span style=" font-size:11pt;font-family:Calibri">Ability
to provide an “SLE-like” forward link service for synchronous link protocols,
initially AOS, but now to include USLP</span></p>
<p style="margin-top:0px;margin-Bottom:0px"><span style=" font-size:10pt;font-family:sans-serif">2.
</span><span style=" font-size:11pt;font-family:Calibri">Provide
encoding in the ESLT for this forward link frame stream</span></p>
<p style="margin-top:0px;margin-Bottom:0px"><span style=" font-size:10pt;font-family:sans-serif">3.
</span><span style=" font-size:11pt;font-family:Calibri">Ability
to accept input frame streams from more than one user source</span></p>
<p style="margin-top:0px;margin-Bottom:0px"><span style=" font-size:10pt;font-family:sans-serif">4.
</span><span style=" font-size:11pt;font-family:Calibri">Ability
to multiplex frame streams from all of the input sources, including some
that are not directly from FF-CSTS itself</span></p>
<p style="margin-top:0px;margin-Bottom:0px"><span style=" font-size:10pt;font-family:sans-serif">5.
</span><span style=" font-size:11pt;font-family:Calibri">Ability
to keep a synchronous forward link filled, if necessary by inserting fill
frames in the ESLT</span></p>
<p style="margin-top:0px;margin-Bottom:0px"><span style=" font-size:10pt;font-family:sans-serif">6.
</span><span style=" font-size:11pt;font-family:Calibri">Ability
to integrate the protocol PDUs from DTN, IP, CFDP, or other data sources,
from “agents” instantiated in the ESLT, to create frames that encapsulate
these PDUs, and to integrate these in the multiplexed frame stream (see
items 3 & 4)</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">As
best I can tell this spec fails to accomplish items 5 and 6 at all, and
it appears to give only passing acknowledgement to items 2 or 4. These
are mentioned as being features that are needed somewhere in the ESLT,
but there is not a section of the document, nor even an informative annex,
let alone a normative one, that would suggest what was really intended
nor how to accomplish it. In my judgement this is a significant oversight
and renders this document inadequate to the task at hand which was to document
how these services were to be provisioned and integrated.</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">Unfortunately,
from my point of view, instead of addressing these absolutely required
services the document as presented spends a lot of “real estate” documenting
how this new service can be made to handle TC forward asynchronous frames.
Since there is already a perfectly serviceable SLE F-CLTU that provides
this service this seems like an unnecessary effort. The only conceivable
rationale that occurs to me is that this TC forward service is very much
like that needed for USLP variable length frame forward service. That
said, I really have to question whether it would have been better to just
modify SLE F-CLTU to accommodate USLP variable length frames instead of
weighing this document down with this added baggage.</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">It
appears that in this document we got far fewer of the essential features
than were required and, at the same time, more features than were really
useful.</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">While
I recognize that a large amount of work has been expended to get this document
to this point, in my estimation it falls far short of what is really required.
It does not provide all of the features called for in the IOAG SISG,
nor that were documented in the SCCS-ARD Magenta Book, nor does it appear
to provide all of the features in the F-CLTU Orange Book which has for
years been supporting major operational missions. It was intended
to provide services that could meet all of these requirements, and it seems
to have failed to do so.</span></p>

a wonderful opening to a letter, right? After looking over, in some

to be able to state that you have addressed my concerns. I believe
that the changes have made the various distinctions among the different
flavors of service provision clearer, and, more importantly from my PoV,
have made the visible the assumptions that were “baked in”, but
not expressed, in service production. This now provided visibility
to the multiplexing functions that are so essential to the proper functioning

I would be curios about knowing who in CESG has been able to fully understand
the requested changes and eventually to track the implemented changes.</span><span style=" font-size:11pt;font-family:Calibri">
</span><span style=" font-size:10pt;font-family:Arial"><br>
IMO, the mechanism of CESG conditions was thought to address changes with
"reasonable/limited scope". <br>
IMO, when changes exceed a "reasonable/limited scope" the document
should return to CESG Poll (or even to Agency Review in some cases).</span><span style=" font-size:11pt;font-family:Calibri">

<p style="margin-top:0px;margin-Bottom:0px"><span style=" font-size:12pt">I’m
guessing that these necessary updates were “visible” to you, and the
rest of the CESG, because you were able to state the magnitude of the required
changes. Perhaps you are asking that the CESG be given an opportunity
to re-review the changes in response to the PID. I cannot tell because
you did not address that issue. But the CESG did get to see the changes.</span></p>
<p style="margin-top:0px;margin-Bottom:0px"><span style=" font-size:12pt"> </span></p>
<p style="margin-top:0px;margin-Bottom:0px"><span style=" font-size:12pt">In
point of fact, the revisions do not make the document “heavily, nor completely
different” from the document that was reviewed. What the changes
do accomplish is to align the description of the service with the functionality
requested in the IOAG SISG report from years ago, which you, yourself,
were a co-author of. What was required were not changes to the FF-CSTS
service provisioning itself, but were clarifications to the service production
that were not otherwise documented anywhere aside from the IOAG SISG report
and the SCCS-ARD. In the absence of these clarifications the functionality
of the service, both provision (which is the core focus of the service
exposed to users) and production (which are the functions that must be
executed to deliver full functionality of frame merging and DTN bundle
agent and CFDP file agent integration) would be inadequately documented.
It would have been left to the users to guess what production functionality
was required or supported. A massive source of ambiguity for a service
that is to be the heart of DTN integration and support in the future ESLTs.</span></p>
<p style="margin-top:0px;margin-Bottom:0px"><span style=" font-size:12pt"> </span></p>
<p style="margin-top:0px;margin-Bottom:0px"><span style=" font-size:12pt">What
is wrong with this approach is that the WG failed to incorporate the description
of these critical production functions in the first place, and that the
CESG failed to catch it earlier. I point the finger at myself here,
since I had the opportunity to catch the issue earlier and did, in fact,
point this concern out a couple of years ago. But then, I am only
one of the six Area Directors. It appears that no one else, including
you, who were one of the authors of the IOAG SISG report that defined this
new service, managed to catch this issue until now.</span></p>
