Hello,
Continuing this topic.
With introducing selection_fields to OVN Load_Balancer row we moved the
responsibility of calculating the hash to ovs-vswitchd
That means we will have potential performance penalty because of that.
I verified what the numbers are.
I took the environment created by O
Hello,
Thanks for working on this.
The change for setting the selection fields for Load_Balancer has been
merged upstream [1].
This change helped a lot and OVN Octavia provider driver (master) is now
able to specify those fields [2] and as effect of it - is able to be
properly tested with tempest

Thanks Maciej for testing.

Hello!
Thank you for discussion and those findings.

Based on the discussion in OVN meeting today I did some more testing, and
here are my findings.
- With ICMP (ping) between same source and destination it is always same
bucket selected by dp_hash.
- With "nc" specifying same TCP 5-tuples, the packets can end up into
different buckets. This is simi
Thanks Numan for the investigation and the great explanation!

Hello!
I would like to ask you to clarify how the OVN Load balancing algorithm
works.
Based on the action [1]:
1) If connection is alive the same 'backend' will be chosen,
2) If it is a new connection the backend will be chosen based on
selection_method=dp_hash [2].
Based on changelog the dp_has
