    9595==  2.6 Modify the OpenFlow Controller to balance throughput among all the TCP flows ==
    9696 - 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
    97  - 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? TCP tries its best to suck up the whole bandwidth so more throughput means network is not congested)
     97 - 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? TCP tries its best to consume the whole bandwidth so more throughput means network is not congested)
    9898 - If you do not know where to start, check the hints in Section 3.
    9999  - 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].
