OPNET

OPNET is a network simulation software used to model, analyze, and test how computer networks perform. It allows engineers and designers to create virtual versions of real networks, including devices like routers and switches, to evaluate how data flows, identify potential issues, and test improvements without affecting live systems. By simulating different scenarios, OPNET helps optimize network design, improve performance, and ensure reliability before actual deployment. It's a powerful tool for planning, troubleshooting, and enhancing complex communication infrastructures in various organizations.
