Time-sensitive network is a set of protocol standards for deterministic real-time communication developed by the IEEE802.1 working group. It defines the time-sensitive mechanism of Ethernet transmission and is suitable for network communication of airborne safety-critical systems; the traffic scheduling mechanism can effectively ensure the real-time and reliable communication of the airborne time-sensitive network, time-aware shaper and frame preemption are typical traffic scheduling algorithms of TSN. Currently, there is no performance evaluation for the transmission requirements of airborne services on TSN. By analyzing the system architecture of TSN and key characteristics of the scheduling algorithm based on the airborne network topology, a transmission delay model of the airborne time-sensitive network is proposed, and the mathematical derivation is carried out. The discrete simulation tool is used to build a network simulation platform, and three typical network traffic scheduling algorithms are verified. The upper bound value of traffic transmission delay is calculated, and the influence of stream characteristic parameters on the selection of scheduling algorithm is analyzed. Finally, the selection of traffic scheduling algorithm in airborne scenarios is summarized.
