[Sis-mia] Updated Green Book, Rome meetings prep

[Grubbs, Rodney P. (MSFC-EO50)]

In word, with Final showing markup, on page 3-9 (not section 3-9), you don’t see section 4 with my comment (see attached screen grab)?

Whoa, same here.

With regards to testing, I agree with Scott, with the additional caveat that (at least one) hop should have an extremely variable level of jitter, and there should probably be packet loss on two nodes: Speaking in an operation scenario, one hop with loss may be from a relay to a lunar lander, while the other would be the lunar->earth link. I’ll take a look at the rest tomorrow.

Thanks,
Jeremy

I'm sorry, Rodney, I somehow lost this email until just now.  I don't see the content on page 3-9 that you are asking about; have you already removed it?  The testing I think would be most important to document would be end-to-end streaming video over a multi-hop path with significant propagation delay (maybe 20 seconds?) and data loss (like 2% packet loss) on at least one of the hops

Scott

Subject: [Sis-mia] Updated Green Book, Rome meetings prep
Apologies for being late with this update.

I have placed an updated draft of our Green Book, version 1.5, in the CWE.  SIS-MIA>Draft Documents>Streaming Services Green Book

This version includes recent updates from Jeremy and Scott.  There is content on page 3-9 where I have asked if anyone remembers why we put that there.  Jeremy/Scott, if you guys could take a look at that and let me know if that is captured in your new content to your satisfaction, I’ll remove.

Once that is settled we’ll consider this our second draft.

One area we need to be thinking about in preparation for the Rome meetings is Section 5.5,  “Common Test Scenarios for Future Study”.  Earlier this summer there was some discussion of testing between JAXA and DLR.  That discussion is ongoing.  If you could please, give some thought to content for this section.

Thanks!
