TSimNet: An Industrial Time Sensitive Networking Simulation Framework Based on OMNeT++

The upcoming IEEE Time Sensitive Networking standard will offer a set of new functionality for Ethernet like frame preemption and frame replication that need careful evaluation. The IETF DetNet working group also works on deterministic layer 3 segments and leverages therefore works from the IEEE group. We present here a simulation framework based on OMNeT++ that implements all non time-based features present in TSN in a modular and easily extendable way. The framework gives other researches a stable base to start evaluating existing and future scenarios. An evaluation of frame preemption as well as per-stream policing based on the framework is presented. It was shown, that frame preemption does not always bring latency advantages and highly depends on configuration of the system. The paper concludes with an overview of the computational cost for the use of this framework.
