Hello RT-list! I'm pleased to announce the TSN-Testbench. The TSN-Testbench is a real time networking simulation (PROFINET RT/TSN, OPC/UA, ...) and validation tool for Linux with PREEMPT_RT focused on strict cyclic workloads. It leverages modern Linux networking technologies such as XDP, XDP/ZC and busy polling in combination with precise time synchronization and scheduled traffic. It generates RT and non-RT traffic, mirrors traffic, performs consistency checks and latency measurements. In a broader sense think of `cyclictest' over the network. It has been tested and used on NIC(s) such as i210, i225/i226 and stmmac. You can get the code and documentation via the git tree at: https://github.com/Linutronix/TSN-Testbench Thanks, Kurt
