CoRE4INET is an extension to the INET-Framework for the event-based simulation of real-time Ethernet in the OMNEST/OMNeT++ simulation system. It was created by the CoRE (Communication over Realtime Ethernet) research group with support from the INET (Internet Techologies) research group at the HAW Hamburg (Hamburg University of Applied Sciences)

 The simulation model is an extension that adds Real-time Ethernet components (hosts and switches) to the standard internet protocol suite. The model is developed in C++ and runs on Windows, Linux and OS X systems. Besides the recording of network metrics it supports the configuration validation by precise messages in the GUI.

CoRE4INET comes with sample networks that show the configuration of networks and the integration of custom real-time applications in the simulation.

CoRE4INET is under continious development and extended with new features. It is used in our evaluation projects and several master and bachelor theses.

                      the realm of computer networking into the time-critical
                      domain. These technologies have started to establish in
                      process automation, while Ethernet-based communication
                      infrastructures in vehicles are novel and challenged by
                      particularly hard real-time constraints. Simulation tools
                      are of vital importance to explore the technical
                      feasibility and facilitate the distributed process of
                      vehicle infrastructure design. This paper introduces an
                      extension of the OMNeT++ INET framework for simulating
                      real-time Ethernet with high temporal accuracy. Our module
                      implements the TTEthernet protocol, a real-time extension
                      to standard Ethernet that is proposed for standardisation.
                      We present the major implementation aspects of the
                      simulation model and apply our tool to an abstract
                      in-vehicle backbone. A careful evaluation that compares our
                      results with calculations obtained from a mathematical
                      framework, as well as with real-world measurements using
                      TTEthernet hardware shows simulation and reality in good
                      agreement.},
