    3636  Question 2. fill up the blanks in function `packet_in` to insert a flow match in the OpenFlow device that allows the packets (as well as those in the reverse path) that match rules in the fw.conf to pass [[BR]]
    3737  Question 3. fill up the blanks in function `packet_in` to insert rules that drops all other packets that does not match the rules specified in fw.conf [[BR]]

    7373 OpenFlow controllers can also make complex flow decisions based on arbitrary state. This is one benefit to removing the controller from the network device — the controller is free to perform any computation required over whatever data is available when making decisions, rather than being constrained to the limited computing power and storage of the network device. For this exercise, you will extend the firewall described in Section 3.1 to include rudimentary denial of service prevention using this capability. [[BR]]
