The controller variable `traffic` contains a list of dictionaries.
Each dict contains the information of one flow, such as `src`, `dst`, etc.
:no_entry: The controller has not accessed to the failure scenario. You are not allowed to read the scenario files from the controller, and you can't use Open vSwitch commands to detect a failure (we use Open vSwitches to simulate silent failures, instead of bringing the interface down). As in a real network, to detect failures you have to rely on the protocols provided by the routers and/or you can implement your own failure detection mechanism in P4 and use it in the switches.
The provided controller already installs the required rules for L2 forwarding onto the switches.
Finally, you may find yourself in need of some additional dependencies.
