Re: [Dots] [Nmop] Request for a solt at Nmop IETF119 [Extended YANG Data Model for DOTS]

[Linzhe Li <[e-mail]>]

Hi Med,

Thanks for your comments. We will make the following main updates:
 * Use cases to make the problem clearer.
 * We've taken DOTS telemetry into account, and we found there is stll some other information worth considering in the data model. We will make this point more clearly.
 * Explain the source of the extension parameters to prove that our assumptions about the client are feasible.

Looking forward to have a further talk with you at the hackathon.

Best regards,
Linzhe

Hi Linzhe,
 
(ccing DOTS)
 
Recorded your request at https://github.com/ietf-wg-nmop/IETF-Meetings/blob/main/119/requested-slots.md. However, I don’t expect a slot to be allocated for this item.
 
FWIW, you may find some quick comments at:
 
pdf: https://github.com/boucadair/IETF-Drafts-Reviews/blob/master/2024/draft-cui-dots-extended-yang-01-rev%20Med.pdf doc: https://github.com/boucadair/IETF-Drafts-Reviews/edit/master/2024/draft-cui-dots-extended-yang-01-rev%20Med.doc
 
The main comment I have is that the Problem to be Solved is not clear enough and seems to not take into account the recent work about DOTS telemetry. I found it useful in the past to have a DOTS use case document with the flow to illustrate the intended functionality. You may inspire from RFC 9387.
 
Some assumptions about the client capabilities in the draft should also be better clarified (e.g., supplying mitigation strategies).
 
There are some issues with the modules themselves, but that’s not important at this stage. These can be fixed once the overall problem is clarified.
 
Hope this helps.
 
Looking forward to have more information from the hackathon.
 
Cheers,
Med

Hi all，
I would like to request a slot to present the draft about extended YANG model of DOTS (DDoS Open Threat Signaling).In the process of deploying dots, we identified some problems and proposed preliminary solutions

We are designing and deploying a collaborative mitigation framework for DDoS attacks. And we noticed DOTS and tried to use it to complete the transmission of important data in the collaborative mitigation framework. However, we and operators, security equipment manufacturers, discovered that both the data channel and signaling channel of DOTS lacked some important data models. This will seriously affect the response speed and mitigation effectiveness of collaborative mitigation parties. Therefore, we proposed a draft to describe the data model that DOTS needs to add.
It is worth mentioning that we will demonstrate the expanded prototype system at HACKAHTON and explain the benefits of the expanded data model.
 
Request Information:
  Title: Extended YANG Data Model for DOTS
  Draft: https://datatracker.ietf.org/doc/draft-cui-dots-extended-yang/
  Presenter: Linzhe Li
  Duration: 10 minutes

Best regards,
Linzhe
