 In order to make this first experience of writing controller easier, we wrote some helpful functions that will abstract some of the particularities of POX away.

 Now let's do a slightly more complicated controller. OpenFlow gives you the power to overwrite fields of your packets at the switch, for example the TCP source or destination port and do port forwarding. You can have clients trying to contact a server at port 5000, and the OpenFlow switch can redirect your traffic to a service listening on port 6000. 
 
-  1. Under the `/local/pox/ext` directory there are two files !PortForwarding.py and myPortForwarding.py that are similar like the previous exercise. Both of these controller are configured by a configuration file at `ext/port_forward.config`. Use myPortForwarding.py to write your own port forwarding controller.
