摘　　要：许多网络应用,如工业控制、自动驾驶等对网络的可靠性要求很高,时间敏感网络(TSN)是基于标准以太网架构演进的新一代网络技术,包含了可靠性的帧复制和消除(FRER)的冗余机制。首先对TSN标准中的冗余机制进行阐述,包括发展过程、相关标准和研究现状,然后对TSN中的空间冗余与时间冗余机制进行分类阐述与分析,最后对时间敏感网络的冗余机制的未来发展和应用场景做出展望,提出一些启发性的研究方向和思路。Many network applications,such as industrial control and automatic driving,have high requirements for network reliability.Time-sensitive networking(TSN)is a new generation of network technology based on the evolu-tion of standard Ethernet architecture,including the frame replication and elimination for reliability(FRER).Firstly,the redundancy mechanism in TSN standard was described,including the development process,relevant standards and research status.Secondly,the spatial redundancy and time redundancy mechanisms in TSN were classified and analyzed.Finally,the future development and application scenarios of the redundancy mechanism in TSN were pros-pected,and some inspiring research directions and ideas were put forward.
