Hello DASH Community –thank you for your time last Wednesday.

This week we have a volunteer @amith...@gmail.com attempting to look at bmv2 fixes for #415 and #436 – thank you Amith!.  In addition, we further discussed changes to documentation, and another round re: the DASH-SAI-Pipeline-Packet-Flow draft.  Detailed notes follow below…

We do have the DASH Behavioral Model call on Thursday 11/16/2023 at 10am Pacific ; please attend if you have ideas or ability to contribute. 

As always, 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.

DASH Community Upcoming Project Action Items

 

 

 

Discussion:

 

-Mircea made some changes to the documentation to clarify the use of ENI in PR455 and Issue454

-Kristina and Mircea discussed a configuration issue related to inbound in Issue452 and requested an update from the SONiC team.

-Marian received approval from the Sonic team for changes made and needs to merge.

-Riff talked about a packet flow document (below); including that the packet flow captures some of the points that are not really defined in the current published documents.  The motivation is to extend what they currently have to make it more flexible.  The plan is to wait for another one to two weeks to close any outstanding issues before merging the document.

-Kristina re-reviewed the entire document during Thursday/Friday 11/2 and 11/3 with recommendations for Riff to review. 

-Bud and Rob reviewed the packet parser changes and found them to be good.
