As a result, users will experience some delay in fetching the flow statistics (i.e., `stats_reply` will not be called right after a !FlowStatsRequest message has been sent in `packet_in` function). Also, it seems that it will take some time for the Open vSwitch to be able to report some flow statistics to the controller. In our experience, Open vSwitch will start to report flow statistics after two flows have already been established. So do not be panic when flow_stats_reply says nothing when one or two flows are already running. |
