Agenda:
1. Administrivia and agenda bashing   - 5 min (Chairs)
Chairs introduce the current status of drafts.

2. Distributed Denial-of-Service Open Threat Signaling (DOTS) Telemetry status update   (draft-ietf-dots-telemetry-08)   - 25 min (Med, Tiru) 
Med: Suggest to use comprehension-optional attributes, thus the key values will consume 3 bytes, the proposal for the value range is 128-255.
Valery: No objection, suggest to discuss this on the mailing list.
Tiru: Telemetry is optional, if using comprehension-required then the DOTS server needs to understand all the attributes. Take this to the mailing list.
Chair: Raise this issue on the mailing list.

Tiru: Support to exchange the map of attack-id and attack-name on the data channel.

Tiru: Do we need to use BLOCK 3 and BLOCK 4 more often because of the poor connections caused by attacks?
Jon: I think so.
Med: I agree with Jon. It's not mandatory.

Chair: Should request YANG doctors' review and Ask the OPS AD to review this draft. Encourage the operators to review.

3. Multi-homing Deployment Considerations for Distributed-Denial-of-Service Open Threat Signaling (DOTS) status update   (draft-ietf-dots-multihoming-04)   - 5 min (Med, Tiru) 
Med: Need more reviews and feedback. Suggest to consider WGLC in Sept 2020.

4. Use Cases for DDoS Open Threat Signaling (DOTS) Telemetry   (draft-hayashi-dots-telemetry-use-cases-00)   - 5 min (Yuhei) 
Options on how to move forward with this draft:
 Opt 1. Require WG adoption after addressing comments from WG.
 Opt 2. Add a high-level use case description to the Telemetry draft. (e.g. Appendix)

Tiru: We should adopt this draft. Prefer option 1.
Frank: Suggest option 2.
Valery: For the implementers option 2 would be better, but if the draft is too long to read then option 1 is better.
Tiru: This is a draft of examples of how to using telemetry.
Chairs: discuss this further on the mailing list.

5. A method for dots server deployment   (draft-chen-dots-server-hierarchical-deployment-02)   - 5 min (Meiling) 
Meiling: Ask for how to move forward with this draft.
Frank: Suggest to clarify the objectives and discuss on the mailing list.
Meiling: The objective is to make recommandations for DOTS agents deployment.
Frank: Feel like that this draft can be combinded into other drafts. I don't see the needs of such a separate document. Getting more discussions on the mailing list will be helpful.
Charis: Suggest to discuss on the mailing list.
