Dear Erik,
As discussed in out last working group meeting, the WG would like to start the AD review of the concept book draft 2: 930x0g-draft-2.docx<https://spacecomm.sharepoint.com/:w:/r/sites/CSS/Shared%20Documents/CSS-CLOUD/Draft%20Documents/ConceptBook/930x0g-draft-2.docx?d=w37e6569186c043f09b3a7627de19f280&csf=1&web=1&e=jtX13G>

Note that there is one late addition for the Cyber Security chapter. I added a discussion of Network Segregation in the Context of CDDS. CDDS may really offer an advantage over SLE and CSTS, as the underlying technologies like AWS Kinesis, Google Messaging, gRPC and others, support out of the box common proxy and inverse proxies. Compared to SLE / CSTS that allows to comply to security regulations without need of dedicated SLE / CSTS proxy systems; quite an advantage.

Best regards,
Holger

Dear Holger,

Thank you for sending the concept document. I have taken a look and have some minor comments and suggestions below. I think once these are addressed then I think we can submit the book for CESG publication polling.

Best regards,

---notes re concept book---


  1.  General: we will need to have .svg kind of graphics submitted separately from the book. Given that the diagrams are done in powerpoint (I think), it should be possible to save the diagrams as .svg files?  Alternatively, perhaps we can include a powerpoint file with the diagrams in the publication package for the secretariat ?
  2.  General:  We should probably generate a "clean" version of the document (i.e., accept all changes, remove comments) to send to the secretariat.
  3.  Probably we should date the book April 2026?
  4.  Figure 1:   I'm not sure that the annotation "CDDS Production State" ( bottom right the diagram) really adds anything to the diagram, given that CDDS Production is already noted.   Maybe just remove the annotation?
  5.  Section 7.3 File extensions -- "Telecommand report files" -- these are already files, so maybe this could just be "Telecommand reports" with a "tcr" extension?

Hello Holger,

A quick message to let you know that I finally had a look at the orange book and provided some comments.  I did this directly via the link provided.

Subject: [EXTERNAL] [CSS-CLOUD] CDDS Updates and Review Request

Dear CDDS Colleagues,
Some updates before our March 11 telecon #2 and a request for your review.

Concept Book
After doing some cleanup and a read-through, the Concept Book draft 2 is in my mind ready to go for AD review:  930x0g-draft-2.docx<https://urldefense.us/v3/__https:/spacecomm.sharepoint.com/:w:/r/sites/CSS/Shared*20Documents/CSS-CLOUD/Draft*20Documents/ConceptBook/930x0g-draft-2.docx?d=w37e6569186c043f09b3a7627de19f280&csf=1&web=1&e=hnfqRc__;JSU!!PvBDto6Hs4WbVuu7!M69bPpzMCCjC6rEnEXy11FJEeFTRPURWQ-dLEOMUj7xTNCBV0gnaaLeGH5eF88Gj4clW24fr5gGKChYJxGGp3yKCkJjt-xHL9sM$>
It would be great if you could do review and provide feedback until before the telecon #2, such that we can take a decision in n March 11.

New Orange Book
To speed up the publication process, and as discussed last time, a CDDS Orange Book has been created based on Blue Book Draft 1: 931x10-O-draft-1.docx<https://urldefense.us/v3/__https:/spacecomm.sharepoint.com/:w:/r/sites/CSS/Shared*20Documents/CSS-CLOUD/Draft*20Documents/OrangeBook/931x10-O-draft-1.docx?d=wf40071f9a7574d65828a95064af8f382&csf=1&web=1&e=fYYCwc__;JSU!!PvBDto6Hs4WbVuu7!M69bPpzMCCjC6rEnEXy11FJEeFTRPURWQ-dLEOMUj7xTNCBV0gnaaLeGH5eF88Gj4clW24fr5gGKChYJxGGp3yKCkJjtJl_OHPE$>
The CDDS Orange Book contains in addition two annexes for gRPC TC and TM services. The idea is to turn / shift the Orange Book into a Blue Book once we can complete the prototyping for the Blue Book.  The Blue Book won't contain the RPC M and TC services; they shall remain in the Orange Book. At the same time the Blue Book is published, the proposal is to update the Orange Book as well to eliminate the material shifted to the Blue Book.

If you have and comments to the approach and of course the Orange Book, please provide them latest for the telecon#2 March11.

CDDS GitHub https://github.com/CCSDS-CDDS/cdds.messages<https://urldefense.us/v3/__https:/github.com/CCSDS-CDDS/cdds.messages__;!!PvBDto6Hs4WbVuu7!M69bPpzMCCjC6rEnEXy11FJEeFTRPURWQ-dLEOMUj7xTNCBV0gnaaLeGH5eF88Gj4clW24fr5gGKChYJxGGp3yKCkJjtWDZ_JtI$>
The CDDS GitHub repository has now gRPC service definitions for the TM and TC as described in the CDDS Orange Book. In addition a little prototype for the TC service as jUnit test is available. That test realizes security based on (self-signed) certificates, that may be interesting. The security approach is also documented in the Orange Book for gRPC services.

Best regards,
Holger

CDDS may really offer an advantage over SLE and CSTS, as the underlying technologies like AWS Kinesis, Google Messaging, gRPC and others, support out of the box common proxy and inverse proxies. Compared to SLE / CSTS that allows to comply to security regulations without need of dedicated SLE / CSTS proxy systems; quite an advantage.
