Yes. OVS patch ports are implemented entirely inside OVS userspace. That is, nothing in the kernel represents a patch port. > 2, Is there any difference between ovs patch interface and ovs + dpdk > patch interface? If yes, do the ovs+dpdk optimize the patch interface; if > no, will the patch interface be ovs performance bottleneck? If you're talking about the Open vSwitch code base, there's no difference; the same code implements patch ports in each case. Patch ports don't have a performance penalty. (If you're talking about the OVDK fork of OVS, I don't know.) _______________________________________________ dev mailing list [email protected] http://openvswitch.org/mailman/listinfo/dev
