I think you're confusing OpenFlow tables with unique sets of wildcards. The former has a limit but each one is not scanned on flow lookup. The later depends on the wildcards in the flows that are written. > How many entry the kernel table can have?

The number of bits that can be wildcarded is large but the number of unique sets of wildcards is usually small in practice. _______________________________________________ discuss mailing list [email protected] http://openvswitch.org/mailman/listinfo/discuss
