CoRE4INET is an open source extension to the INET-Framework for the event-based simulation of real-time Ethernet in the OMNEST/OMNeT++ simulation system. It provides real-time Ethernet protocols like AS6802 and AVB. It was created by the CoRE (Communication over Realtime Ethernet) research group at the HAW-Hamburg (Hamburg University of Applied Sciences).

CoRE4INET Environment


  • Updated to support OMNeT++ 5.5.1 and INET 3.6.6
  • Added IEEE 802.1Qci filtering and TSN nodes.
  • Added IEEE 802.1Qbv shaping. (Including scheduled gate control list and credit based shaper)


  • Best Efford Crosstraffic
  • IEEE 802.1Q / IEEE P802.1p VLANs and Priorities
  • Time-Sensitive Networking (TSN)
  • IEEE 802.1 Audio/Video Bridging (AVB)
  • TTEthernet (AS6802)
  • IP over Realtime-Ethernet


CoRE4INET was first introduced as TTE4INET at the 4th International Workshop on OMNeT++ (2011) along with the 4th International ICST Conference on Simulation Tools and Techniques (2011). You can find the publication and slides here.

Since there were changes necessary to support OMNeT++ 4.2 and INET 2.0, it was completely redesigned. When more real-time Ethernet protocols were added the project was renamed from TTE4INET to CoRE4INET to show that it does not only contain time-triggered protocols.

The CoRE4INET model is under continuous development: new parts are added, bugs are corrected, and so on. We cannot assert that the implementation will work fully according to the specifications. YOU ARE RESPONSIBLE YOURSELF TO MAKE SURE THAT THE MODELS YOU USE IN YOUR SIMULATIONS WORK CORRECTLY, AND YOU'RE GETTING VALID RESULTS.
