Since we have previously disabled Forwarding, flows added by the Static Flow Pusher will be the only flows present on the switches, and thus only traffic permitted by these flows will traverse the OVS network. These flows essentially take packets from a particular ingress port and send them out a destination port. To do this, we need to determine the port numbers Floodlight has associated |
