Comparative Analysis of Time-Sensitive Network Scheduling and Traffic Shaping Mechanisms for A380 Aircraft Network Topology

Time-Sensitive Networking (TSN) has been deployed in time-critical industrial and automotive applications, and numerous studies have evaluated TSN scheduling mechanisms for industrial and automotive network topologies, but there is a clear lack of comparable studies for the avionics network topologies. This paper fills this gap by evaluating three widely used TSN scheduling algorithms on an Airbus A380 network topology using the OMNeT++ simulation framework. Each algorithm is evaluated in four simulation cases with varying amounts of side traffic in the network. Asynchronous traffic shaper (ATS) exhibited the unimodal distribution of end-to-end delays with a strong positive skew and peak values for both Best-effort (BE) and Time-critical (TC) traffic.
