SDN4CoRE

SDN4CoRE (Software-Defined Networking for Communication over Realtime Ethernet) is an open-source extension for the event-based simulation of programmable (software-defined) real-time Ethernet networks in the OMNEST/OMNeT++ simulation system. It is based on the INET-Framework, providing internet technologies, the CoRE4INET Framework, providing real-time Ethernet protocols such as AS6802, AVB and TSN, and the OpenFlow Framework, originally developed at the University of Würzburg, Germany, providing a programmability option via the OpenFlow protocol. SDN4CoRE provides programmable network devices and controllers for different Ethernet extensions such as IEEE802.1Qbv and AVB (including SRP) and various management protocols such as NetConf and OpenFlow. It was created by the CoRE (Communication over Realtime Ethernet) and the INET (Internet Technologies) research group at the HAW-Hamburg (Hamburg University of Applied Sciences).

    • Check [Abstract Network Description Language] | [CoRE Simulation Model Installer] | [Gantt Chart Timing Analyzer]
  5. Get CoRE framework (GitHub or CoRE Simulation Model Installer)
    • GitHub: Clone framework and import it in OMNEST/OMNeT++
    • CoRE Simulation Model Installer: OMNEST/OMNeT++ -> Help -> Install CoRE Simulation Models...
  6. Get our original fork of the OpenFlow framework (GitHub)
    • GitHub: Clone framework and import it in OMNEST/OMNeT++
  7. Get SDN4CoRE framework (GitHub)
    • GitHub: Clone framework and import it in OMNEST/OMNeT++
  8. Working with the framework

IMPORTANT

The SDN4CoRE 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.
