Description
Summary:Highly reliable, scalable and deployable net-works with strict temporal constraints are inevitable for future cyber physical systems. Due to widespread usage and success of Ethernet technologies, the Time Sensitive Networking task group introduces a series of protocol extensions to the IEEE 802.1 Ethernet standard. These standards provide real time capabilities and performance improvements. Simulation environments are intensively used to investigate correctness and applicability of new protocol suites. This paper presents an OPNET simulation framework for simulating TSN time-based features. Our framework implements ingress time-based policing and enhancements for scheduled traffic as an extensions of the Ethernet standard. We describe the implementation details of our simulation models which provide temporal properties. We also evaluate and compare our results with the expected behaviors of the aforementioned protocols.
