I disagree only about one
statement; i.e. "MIA Green Book, being non-normative, can (IMHO) say
whatever it wants" <br><br>
In this respect I suggest the MIA Green Books adding a remark to state
that the used TCP CLA is not standardised yet. <br>

<b>Subject: </b>RE: MIA Green Book 730.2-G-0<br>
<br>
Interesting question. I think this would entail a substantial
reworking of figure 3.3, because the application data units (which become
bundle payloads) issued by the transparent gateway never go into a file
at all and therefore would bypass CFDP altogether. The figure 5.2
protocol entity would appear between the “live stream” application box –
which in this case would be the transparent gateway, but which we are
removing for simplicity – and the box labeled “BP”. I’d prefer not
to make this substantial revision to that 901.1-M-1 diagram here,
though.<br>
<br>
The organizational relationship between the bundle payload and the other
blocks of a Bundle is described in detail in 734.2-B-1. Again, I’d
like to avoid recapitulating the material in other books in this Green
Book if possible.<br>

Makes sense to me. For Fig 3.3 I like showing the two different
paths, file based and RT, but I agree it would make the figure more
complicated.<br>
<br>
In Fig 5-2 I might be tempted to show the relationship between the Bundle
Payload, as Scott described it, and the Bundle Header. Let me also
ask you to think about just where on FIG 3.3 the Fig 5.2 protocol entity
would appear. Between which two boxes?<br>

<b>Subject: </b>RE: MIA Green Book 730.2-G-0<br>
<br>
Walt, I agree with Peter: let’s remove the live stream notation from
figure 3.3. We don’t have to show all possible configurations in
this figure, and if we do want to show live streaming from the ground
then we have to show a corresponding live display on the spacecraft,
which makes the diagram too complex.<br>
<br>
On figure 5.2, I think the main problem is the caption. This figure
does not show the structure of a gateway, as one might reasonably guess;
it shows the structure of the payload of any single bundle that is issued
by the “transparent gateway” application. I would propose the
following:<br>
· Change the caption for
figure 5.2 to “Payload of bundle from transparent gateway”.<br>
· Change the label at the
top of the diagram from “single bundle” to “payload of a single
bundle”.<br>
· Remove the block at the
bottom of the diagram that says “bundle protocol – generated by
gateway”.<br>

Hi Walt,<br>
<br>
I'm ok with Fig 3.3 and I like the addition of your video user
services. The only issue I have is that there is a flow on the RHS
labelled "Live Stream" that flows into the "User File
Application". In my reading of this that should be a stream of
video data that gets flowed directly into some sort of video to bundle
process, not into a "file application" and from there directly
into a Bundle Protocol (BP) agent. Somewhere, presumably on
the Space User Node, there should be a reverse process that would accept
bundles, extract video data, and send a "live stream" to a
video display. I do not see that. My suggesitons is that you
either address all of these bits and pieces for a live stream or leave it
off and just show the video buffered in a file.<br>
<br>
In Fig 5.2 I still have no idea what you are trying to say. This is
titled " Overview of Transparent Gateway", and I provided the
note before that said:<br><br>
<b>Sorry, but I find this figure confusing. It’s labelled, at the
top, “Single Bundle”, but it includes what appear to be a “gateway
header”, packets, BP, BSSP, and lower layers. Just what is it
trying to show?<br>
</b><br>
I am still confused. Is it a "Gateway" connecting two
different domains or is it a single bundle? If it is a
"Gateway", what are the stacks for the two (presumably
different) domains and what is the nature of the gateway function?
If it is a "Single Bundle" where is the bundle header and how
is the data within the bundle structured?<br><br>
Trying to help here, but I get that this may be a little tiresome.
Looking for clarity.<br><br>
Thanks, Peter<br><br>

CFDP may run over space data link protocols (such as e.g. CCSDS Advanced
Orbiting Systems [AOS]) as well as the Bundle Protocol, but in the
context of this book, exclusive focus is on the Bundle Protocol transport
<br><br>
Another small remark is on figure 6-3 where an arrow is labelled
"Bundled Protocol" and it may be the final "d" on
Bundle is too much. <br><br>

Gian Paolo, we have reviewed your comments to our Green Book and I
believe resolved each one. I’d like to find some time to review
them with you. <br><br>
The attached document includes in the notes each comment we received from
the CESG (in context), and with "track changes" shows how we
have resolved the comment. <br><br>
Regarding your comment: <br><br>
Gian Paolo Calzolari - Last but not least I think that a feedback effect
(e.g. Technical corrigendum) to CCSDS 734.2-B-1 is required for Annex B
y=that contains the Convergence Layer Adapters (CLAs).<br>
Clause in B2.1 states "Compliant implementations shall implement at
least one of the CLAs in this section." but, as the (normative)
Annex B defines the following 3 CLAs<br>
- LTP CONVERGENCE LAYER ADAPTER<br>
- UDP CONVERGENCE LAYER ADAPTER<br>
- CCSDS ENCAPSULATION SERVICE CONVERGENCE LAYER ADAPTER<br>
then BSSP would not be not BP compliant.....<br>
Therefore it looks wise adding there the definition of a TCP CLA and/or
stating something in B2.1 that the list of CLAs in Annex B is not
exhaustive.<br>
I also noticed that (normative) section A6 BASIC REQUIREMENTS mentions
adapters referring to sections B3.1.2 and B4 but not B5 (i,e. the CCSDS
ENCAPSULATION SERVICE CLA defined in B5 and the LTP CLA for Unreliable
transmission defined in B3.1.3 should be added to the table in A6).
<br><br>
Since that comment really relates to a DTN book, I asked Keith to
comment. Here is his response: <br><br>
If you ONLY implemented BSSP then it wouldn’t be compliant. But for
a BP-compliant implementation if you implement UDP and BSSP, or LTP and
BSSP, you’d be good. I think you can recommend using BSSP if you
like (really, anything since it’s a Green Book) and leave the requirement
from the BP Blue Book alone.<br><br>
<br><br>

You may want to review the document before we chat. Or, after
reviewing the document, you hopefully will be content that we’ve resolved
everything. If that is the case, I would just need a note from you
indicating such for my records. <br><br>
Thanks! <br><br>
