Design and Analysis of a Time-Sensitive Networking Simulation Model

As a new communication technology for Industry 4.0, Time-Sensitive Networking (TSN) provides reliable support for real-time data amidst massive data transmissions. However, manually verifying the overall performance mechanisms of such a network is challenging. Therefore, this article models and simulates the TSN network on the OPNET platform. First, the key mechanisms and current development status of Time-Sensitive Networking are introduced. Next, the simulation modeling of the network switches and end systems is described, highlighting the key technologies within the model; where the end systems are responsible for data generation, transmission, and processing, and the switches are responsible for data forwarding and routing. Finally, this article designed the initial data of the TSN model and completed the testing of the model under a certain network bandwidth, with an almost zero packet loss rate for high-priority data packets, and the end-to-end delay meets expectations. Although the packet loss rate and delay for medium and low-priority data are slightly higher than those for high-priority data, they still meet expectations.
