Network Simulation Experiments Manual, Second Edition, enables networking professional to visualize how networks work by providing free access to easy-to-install OPNET software. This software provides a virtual environment for modeling, analyzing, and predicting the performance of IT infrastructures, including applications, servers, and networking technologies. The book also goes a step further by providing detailed experiments on core networking topologies for use in this simulation environment. Each experiment is also accompanied by review questions, a lab report, and exercises. This book is recommended for graduate students and networking designers and professionals. - Useful experimentation for professionals in the workplace who are interested in learning and demonstrating the capability of evaluating different commercial networking products - The experiments in this manual are closely tied to Peterson/Davie: Computer Networks, fourth edition (a best-selling Morgan Kaufmann title), making it a perfect companion book.
