[Sis-mia] Description for proposed new project

Tue May 30 18:33:49 UTC 2017

I wondered whether the book as proposed should be a Magenta Book.  In the past we’ve received feedback from the CMC on what color a project should actually be, vs. assumptions we made early in the process.

I agree with the notion of a teleconference this summer prior to technical meetings in November.  I think our priority now is moving forward with the revision to the Charter, and Scott can let the CMC know that we have a project proposal being iterated between now and Fall technical meetings.

Agreed?

I also concur with Osvaldo, reading from the text it is mostly about best practices rather than new interface/protocol/architecture specifications. As such, I would see more appropriate to go for a magenta rather than blue book, which would also be lighter in terms of requested effort, since no prototypes are necessary there.
As to the urgency of such project, if such, we may want to organize a telco (provided that we find a reasonable time to let USA, Asia, and Europe people to join) and discuss the matter. Otherwise as suggested by Osvaldo we can safely wait until Fall Meetings in the Nederland.

Hi All
It is any reason why we need to have a blue book now and not a Magenta one? Or do we have any hurry?
It will be (in my opinion) more reasonable if we have a MIA meeting in the Hague and discuss what we really want to do and agree after that which prototypes and test we will need to develop and carry out.
After we have the meeting and a clear plan we can decide if we go for a blue book or not
From a CMC point of view it is too early and too vague (also with the update from Jeremy) to be approved
Any ideas?
Best Regards
Osvaldo

Hi Rodney,

Just a few comments from my side:

1)      I think it would be better to explicitly state what is the MIA blue book (i.e., CCSDS number and title).
**  My understanding is the book can’t get assigned a CCSDS # until it is an approved project.  As for the title, I’m open to suggestions if the current proposed title isn’t appropriate (“RTP for Space Applications”).

2)      In my impression we need more details about the overall focus of this blue book. It is stated that BP cannot support ordered delivery of video frames (what about using e2e DTPC?) and RTP is proposed. Does it mean that RTP (over UDP/IP I guess) shall be used in alternative to BP or are we going to propose a new CLA to make RTP interoperable to BP? Some more details about the proposed protocol architecture I think are necessary.
**  Good points.  My thinking was this offers an alternative method for streaming video (and voice) than what is outlined in our current motion imagery blue book.  Jeremy/Osvaldo, if you could please, make some suggested edits based on Tomaso’s comment?

3)      I think it would be good to draft a tentative timeline and also check internally which agencies are willing to commit resources to this blue book (for the 2 prototypes generation), who is the book editor, who is contributing and who is observing (if any).
**  We would follow the template for a blue book in the CWE.  One of my actions below was asking which agencies were interested in committing resources to the blue book for the prototypes.  NASA will provide the book editor as we have for other MIA activities.

Hope it can help

Cheers,

Tomaso

All—during our meetings in San Antonio, DLR/Jeremy Mayer proposed a new project, likely a Blue Book, related to the use of RTP for video (and voice).  One of the reasons I circulated a draft for an updated charter was to pave the way for this new project, and perhaps subsequent projects like it.

Attached and in the CWE (SIS-MIA>documents>draft documents is a draft project description.  Two actions for you, please.  Please review and provide any suggested edits or comments to me and Osvaldo Peinado by COB June 2.
Please let me and Osvaldo know whether your Agency could commit to some level of resources to support development of a Blue Book (which requires 2 prototypes for publication), also by June 2.

WRT commitment of resources, formal commitment would come as part of the CMC process, but we will need to know of likely interest to put forward the project proposal.

Thanks!
