Packets for new flows are handled in userspace with a classifier that is capable of handling wildcards. Future packets in that flow are handled by an exact match table in the kernel. > 2) Is there any difference between rules with wildcard field and exact > rules? > 3) what is the effect of huge number of rules on the performance of > openvswitch The userspace table is mostly proportional to the number of unique sets of wildcards. The kernel table is not affected by the number of OpenFlow rules. _______________________________________________ discuss mailing list [email protected] http://openvswitch.org/mailman/listinfo/discuss
