OMNeT is a public-source, component-based, modular and open-architecture simulation environment with strong GUI support and an embeddable simulation kernel. Its primary application area is the simulation of communication networks, but it has been successfully used in other areas like the simulation of IT systems, queueing networks, hardware architectures and business processes as well.

See the main OMNeT website omnetpp.org for documentation, tutorials and other introductory materials, release downloads, model catalog, and other useful information.
