Hi guys. I'm using an openflow controller to poll the ovs each second, from this I'm getting the flows passing through the switch ans other relevant information.
I made a topology similiar to this. Host1 --- OVS1 ---- OVS2 ---- OVS3 ---- OVS4 --- OVS5 --- Host2 I'm generating traffic from Host1 to Host 2 using iperf and all hosts and switches are generated by Mininet. I'm polling all the switches on the same time and I noticed that OVS1 doesn't have more traffic passing through it than the OVS5 or any other switches. This seems strange, since I'm polling the switch from the beginning of the flow, so the traffic from OVS1 should be bigger than OVS2 and OVS2 traffic > OVS3 traffic > OVS4 traffic > OVS5 traffic. But this doesn't happen. Just some more considerations, I'm sending one traffic on each experiment and I've tried with UDP, TCP and video streaming (not iperf), but all looks the same. I'm getting the total traffic already passed through a flow. Thank you.
