This is due to the flow installation process triggered by the first ping (Specifically, the ARPs sent by the hosts) as the switch suffers a flow table miss.

Therefore, if you have a Mininet install, you get OVS for "free". You can use OVS directly for your data plane. 126 126 127 127 = II More complex examples = 128 You can launch multiple instances of Floodlight on one or more nodes. If you decide to run the instances on a single host, the ports used by the Floodlight instances must not conflict i.e. each instance must be assigned a different set of ports. 129 128 You can launch multiple instances of Floodlight on one or more nodes.
