Run example tcp-variants-comparison.cc which is available in examples/tcp directory in ns-3. Several ‘.data’ files will be created in the ns-3 root directory. Plot the TcpVariantsComparison-cwnd.data file using gnuplot. Follow the steps given below for completing this task:

1. Configure ns-3 using command: ./waf configure --enable-examples
2. Build ns-3 using command: ./waf
3. Run the example tcp-variants-comparison.cc using below command:

         ./waf --run "tcp-variants-comparison --tracing=true"
   

4. Check if the file TcpVariantsComparison-cwnd.data is created in the ns-3 root directory.
5. Use gnuplot to plot this file. The resultant graph should follow the guidelines given below:

    Format of the graph: .png
    Name of the image: cwnd.png
    Type of Graph: Line Graph
    X-axis label: Time (in Seconds)
    Y-axis label: cwnd (in Bytes)
    Title of the graph: Congestion Window Plot
    Position of the key: outside and top right corner
    Line width: 2
