Hi Abbasi,
Actually If you are working with openvswitch It has unlimited flow limit.
If you are working with a hardware-based SDN switch you have to estimate
the limite by getting its TCAM size (usually in MB) and check the size
field of your installed flows. So that you can divide these numbers and
have a ideia of how many flow rules your switch can support.
By the way, are you working mainly about flow rule limitations? If so,
please contact me by e-mail If you desire as it is part of my master thesis.
Best Regards,
Túlio Pascoal
