One method to make this information "stick" is to create an environment where networking professionals and students can visualize how networks work, utilizing software that simulates the functions within the network. Tool itself is very useful because it provides a virtual environment for a variety of desirable features such as network modeling based on certain criteria and predicting its performance. Network Simulation Experiments Manual takes an instructional tool a step further and provides detailed experiments on core networking topologies for use in a simulated environment. * The experiment in this manual closely related to the Peterson / Davie: Computer Networks, 4E, a Morgan Kaufmann bestselling titles * Software download based on superior product made by OPNET Technologies, Inc., the software used by thousands of commercial organizations and governments around the world, and with more than 500 universities * Useful experiments for professionals in the workplace who are interested to learn & demonstrate ability to evaluate different products commercial network
