Review of Research on Time-Sensitive Networking Testing

With the advent of the Industry 4.0 era, the demand for precise time synchronization and high-speed data communication has been steadily increasing across various industries. In this context, Time-Sensitive Networking (TSN), as a significant enhancement of traditional Ethernet protocols, is gradually becoming a core enabling technology in multiple fields due to its technological advantages, including accurate time synchronization, high bandwidth, low latency, and high determinism. This paper first reviews the major protocol standards of Time-Sensitive Networking (TSN) and its current state of development, providing a detailed summary of the key characteristics of TSN technology. Next, it focuses on analyzing the latest research advancements in the field of TSN testing, both in academia and industry, covering the development of theoretical frameworks, the design of verification schemes, and the construction of testing tools and experimental platforms. Furthermore, this paper summarizes and reviews the technical features and application practices of TSN testing products developed by several companies, highlighting the efforts and achievements of the industry in advancing the maturity of TSN testing technologies. Finally, the paper concludes by summarizing the key points and proposing potential directions for future research.
