Hi, When doing netperf TCP_CC and TCP_CRR with openvswitch-2.0.0 on CentOS6.3(2.6.32-279.19.1), we found Megaflow which supposed to boost flow setup rate does not take effect. ovs-dpctl shows many flows that match tcp source port. Our flows are setup like this: in_port=20,dl_src=XXXXXX,dl_dst=XXXX actions=set_field:0xXXXX->tun_id,output:36, it's not necessary to match tcp source port.
However, when using actions=normal flow, flows in kernel are indeed setup like megaflow, that is being wild carded. We are not very familiarly with the implementation details of kernel datapath, can anyone suggest what's the mechanism of megaflow and what should we do to utilize megaflow? _______________________________________________ discuss mailing list [email protected] http://openvswitch.org/mailman/listinfo/discuss
