The Frame Replication and Elimination for Reliability (FRER) redundancy mechanism in Time Sensitive Network (TSN) improves the reliability of the network through the replication and elimination functions of data packets. Data packets are copied onto the redundant paths through replication function, and then the paths are merged and the elimination function removes duplicates. This redundancy scheme affects the timing behavior of the TSN, resulting in increased end-to-end uncertainty. To this end, by combing the Time Aware Shaper (TAS) algorithm, the delay problem caused by the FRER mechanism is reduced by setting different gating parameters, and a worst-case delay calculation model based on Network Calculus (NC) is provided for airborne TSN, and the upper bound of end-to-end delay in multi-service data transmission is quantitatively analyzed to evaluate whether the airborne network under TSN meets the communication requirements. Finally, the network topology of certain aircraft is simulated by OMNET, which verifies the applicability of TSN technology in civil aircraft avionics network and the availability of this model for end-to-end worst delay analysis of airborne TSN communication system, and provides a basis for network resource optimization.
