+To restart Trema controller as well as the attached switch: 
+{{{
+1. kill trema process: kill $(pidof ruby) 
+2. delete lock file: rm /opt/trema...../tmp/pid/controller.pid  (controller is the name of your controller, in the case of Load Balancing, its `Load_Balancer`)
+3. unlink the switches from controller: ovs-vsctl del-controller br0
+4. start controller: /opt/trema....../trema run controller.rb (controller is the name of your controller, in the case of Load Balancing, its  load_balancer.rb)
+5. link switches to the controller: ovs-vsctl set-controller br0 tcp:127.0.0.1 
+ (might need to wait for 2 seconds for the switch to connect to the controller, to verify that, print something in the "switch_ready" function so that you can see the output when switch is connected)
