There exists this Exact Match Cache(EMC) per PMD thread and has 8k entries to cache flows. In case of lookup failure the packets are sent to datapath classifier. The dpcls can have multiple subtables and key lookup is done on each subtable till a match is found. Note that there exists a classifier per ingress port in OvS-DPDK master! - Bhanuprakash. _______________________________________________ discuss mailing list [email protected] https://mail.openvswitch.org/mailman/listinfo/ovs-discuss
