[ovs-discuss] 答复: [ovs-dev] Why are iperf3 udp packets out of order in OVS DPDK case?

Ian, here is my configuration, sorry I can't show flow details because it is confidential. By the way, iperf3 tcp is ok and performance is good enough, I'm really confused, udp was ok but tcp were not ok in my VM environment before, it broke my sense :-), I can avoid out of order issue if I

[ovs-discuss] Flow comparison with OFPFlowMod message

Hi, In my project I need to compare an active flow in the table(obtained from `EventOFPFlowStatsReply`) with a OFPFlowMod message that is sent to the controller. I've thrown together a method to compare the two but it doesn't look good. Is there a better way to do this? ``` def

Re: [ovs-discuss] Query on DEC_ttl action implementation in datapath

I think it was considered cleaner from an ABI perspective, since it doesn't require another action, since "set" was already supported. In practice, I don't think it's a problem, since usually a TTL decrement is associated with a routing decision, and TTLs tend to be fairly static between two
