DASH Workgroup Community Update 1/15/2025
Kristina Moore
Hello DASH Community –thank you for your time yesterday.
This week we quickly touched upon the 12 closed PRs from over the break and discussed the ‘in-progress’ and ‘awaiting review’ items for updates. Please find below the full discourse and follow-ups. As a reminder, Synogate has offered to present their Packet Processing Pipeline proposal at a future date – I’ll send an updated agenda to include this topic once we have a date finalized.
In Summary
(full list below),
since the last Community call we have:
3 PRs/Issues completed (-9)
9 in ToDo (+/- 0)
1 in Draft
16 in Progress (+1)
8 Awaiting Review (+1)
For further reading, see
full meeting notes and follow-ups below in this thread.
Just a reminder that we would encourage/invite Community members to present to the Community (test runs or progress, new scenarios, etc…), just ‘r’ to let me know, or generate a PR in the repo.
Follow-up tasks:
· LF Username Transition: Transition user names to the Linux Foundation. (Kristina)
· Synogate Packet Processing Pipeline Presentation: Schedule a presentation for the packet processing pipeline idea
· Local Region ID: Merge the update to include the local region ID change after passing all checks
· Review Smart Switch Related Tables: Resolve the conflict related to the smart switch tables and get it reviewed (Yakiv)
· Upload Images: Upload images for the floating NIC document and insert them into the text. (Kristina)
Thank you for your time/contributions –
see you on 1/22/2025
With respect to
any of our DASH meetings - Community (Wednesdays), or Behavioral Model (Thursdays) –
please let me know if there are PRs, Q&A, or items you would like to discuss or present.

TL:DR DASH Community Notes 😊
· Project Progress: Reviewed the progress made over the break, highlighting that 12 PRs were completed.
o The meeting last week had fewer attendees due to an unexpected schedule change to Thursday, with nine or ten people attending.
· Linux Foundation UserName Transition: Transition of usernames to the Linux Foundation is still pending and on her to-do list.
· Local Region ID Merge Approval: Kristina received approval from Mukesh to merge a change related to the local region ID, but it needs to pass all checks. Riff will look into the issue/dependency.
· Underlay TTL and HA Session Parameter: Nvidia mentioned that the changes to the underlay TTL and HA session parameter are not ready to merge yet, as they are working on other essential gaps in the behavioral model.
· Floating NIC Document: Kristina is uploading images for the FNIC document publication, Kristina and Riff working on text next.
· Smart Switch Related Tables: Kristina mentioned that a task related to smart switch tables needs a conflict resolution and is awaiting a review..
· PTF Test Cases for DASH Flow: Riff noted that the test cases are dependent on the Data Plane App, which has already been merged, so the test cases can now proceed. Review requested from Riff.
· Per-Action Production Parameter Support: Looks like this is ready to close, checked w/JimmyZhai.
· Synogate Packet Processing Pipeline Presentation: Synogate expressed interest in presenting their packet processing pipeline idea, which includes a smart algorithm for session state management. Asked Phillip to schedule the presentation.
