To run the project:

1. First run 'main.py' to detect the topology and save in to the file (default 'routers.dat') $ python main.py
2. Any of the 'task1.py', 'task2.py', 'task3.py' can be run when 'main.py' successfully finished its job: $ python task1.py

Only data which is necessary for building a plot is output to STDOUT. Everything else is output to STDERR. If everything needs to be redirected to STDOUT, should be invoked as follow: $ python task2.py 2>&1
