[Sis-csi] Cislunar Section 8 - definitions and stacks

[Keith Hogie]

Chris,

  In reviewing your other examples and trying to figure out a what we 
should use, I ended up trying to see if there were some categories we 
could identify for all the types of data flows.  Then we could do an 
example for each case.  I put some thoughts in the file and tried to fit 
your first example into those definitions. 

I'm not sure where this is going but in the process of trying to fit 
your example into the categories I found that the example starts by 
discussing a transfer down and then ends up describing a transfer up.  
So running through the checklist of categories actually had some use.

I also noticed that your relay node did not go high enough to do the 
CFDP processing.  It shows a relay node with no storage and that only 
does packet forwarding.  I inserted an alternate diagram that tried to 
put more emphasis on the network layer, file storage locations, and RF 
links.  It also doesn't include lower layer details to avoid any 
conflict with other working groups.

I didn't get down to proposing any alternate scenarios yet.  Some 
initial thoughts are:

1 - Traditional satellite/rover scenarios - GROUND controlling 
satellites/rovers, data dumps, etc.
2 - Traditional MANNED scenarios - voice, video, telemetry
3 - More elaborate scenarios with RELAYS at network layer and above for 
realtime and file store-and -forward  (not TDRSS, or other RF relay)
4 - Non-Earthly scenarios with unmanned and manned interaction without 
Earth contact
5 - Scenarios with MULTI-PARTY communication, not just two endpoints

See what you think
