This simulator is created to test the performance of a network managed by a logically-centralized SDN-controller using the Discrete Event Modelling and Simulation Methodology DEVS. The simulator is very simple and can be extended to evaluate the performance and limitations of Software-Defined Networks in large-scale networks. To excute the simulator: -------Navigate to the project folder-------- -------Compilation--------------------------- $ make clean; make all -------Testing atomic models---------------- $ cd bin ./SENDER_TEST $ ./PROCESSOR_TEST $ ./FLOWTABLE_TEST $ ./CONTROLLER_TEST $ ./RECEIVER_TEST -------Testing the simulator---------------- $ ./OFP ../input_data/input_ofp.txt -------clean----------------------- rm -f bin/* build/*
