The OPNET IT GURU has been in existence for years and designed to be used for the industry and the academics. The simulation software is now in version 10.0 and equipped with abundant features such as: modeling network topology and traffic, application impact assessment, and server capacity planning. The features of modeling network topology and traffic are ideal for network engineers to experiment different kinds of scenarios before implementation of any networks, which in turn could cost the organizations less on the IT budget. The application impact assessment is useful when measuring the end-to-end time of the deployed or to-be-deployed applications. The end-to-end response time is important to EC transactions. The server capacity planning can be used for IT departments to do what-if analysis before they reallocate IT resources such as production or application servers.
