The“on time and deterministic”scheduling and transmission mechanism of Time-Sensitive Networking （TSN）can effectively improve the determinism of information interaction in industrial automation systems and vehicle integrated electronics systems. Therefore，TSN has potentially become one of the candidates for high-deterministic networking of avionics systems. However，how to match its various time-sensitive shaping and scheduling mecha⁃ nisms with the airborne networking environment and requirements is the primary problem to be solved at present. Based on a summary of current TSN standards，this paper firstly analyzes the requirements of airborne networking. Then，the latest progress of current TSN related research is summarized from the perspectives of TSN scheduling opti⁃ mization and delay boundary analysis. This paper also discusses the challenges and key technologies of TSN in the airborne environment in terms of protocol tailoring，system management，model engineering，reliability and security，and wireless hybrid transmission.
