What is Omnet++?

OMNeT++ is a modular, component-based C++ simulation library and framework, primarily for building network simulators. It's widely used for modeling communication networks, queuing networks, hardware architectures, and business processes. OMNeT++ provides a component architecture to easily define simulation topologies, message passing mechanisms, and statistical data collection capabilities. Its primary strength is its flexibility and extensibility, making it suitable for both research and industrial applications.
