Hi,
We want to make some OSV code modification in order to obtain fuctionality
desribed in https://arxiv.org/pdf/1805.07993.pdf
Strictly speaking wa want to implement the part related to Figure 4 on page
10. In shortcut, the proposed mechanism uses 2 flow tables (Detailed and
Coarse Flow Table, DT
ld be placed in
the code? Thank you in advance.

I'm taking about hash based on which flow table is looked up in kernel data
path.

Hi Jason
I have the same doubts - I would like to connect balance-slb in OpenStack
Rocky to two separate switches.
I see you wrote this post a few years ago.
Have you figured it out finally?
Thank you in advance for your reply
