TTE4INET is an extension to the INET-Framework for the event-based simulation of time-triggered Ethernet ( TTEthernet) 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 TTEthernet 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.
TTE4INET comes with sample networks that show the configuration of networks and the integration of custom real-time applications, that use the TTEthernet-API, in the simulation.
TTE4INET is under continious development and extended with new features. It is used in our evaluation projects and several master and bachelor theses.

abstract = {Real-time extensions to standard switched Ethernet widen
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.},
