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 productsThe 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.
