    v23 v24  
    9898 - You need to calculate the average per-flow throughput observed from both left and right path in function "stats_reply" in your load-balancer.rb
    9999 - In function "packet_in", change the path decision based on the calculated average per-flow throughput: forward the flow onto the path with more average per-flow throughput. (Why? Hint: TCP tries its best to suck up the whole bandwidth)
    100  - If you do not know where to start, check the hints in Section 3. If you really do not know where to start after reading the hints, download the answer directly from [http://www.gpolab.bbn.com/experiment-support/OpenFlowExampleExperiment/ExoGENI/load-balancer-solution.rb Here].

     101  - If you really do not know where to start after reading the hints, download the answer directly from [http://www.gpolab.bbn.com/experiment-support/OpenFlowExampleExperiment/ExoGENI/load-balancer-solution.rb Here].
    101102 - Redo the above experiment (the one with some lossrate on the left path), check the graphs plotted on !LabWiki as well as the controller's log on node "Switch" at /tmp/lb.tmp and see the difference.
    102103 - If you have more time or are interested in trying out things, go ahead. The tutorial is over now and feel free to ask questions :-)
