Hi, Thanks Abbasi and Túlio! I miss-understood that.
> Is *total_capacity = n_table * max_entries* correct? I guess it is right. but as Túlio said, it is highly depending on the implementation of your switch. When I tested a hardware switch before, the throughput of that switch declined significantly around the number of n_table * max_entries.
