Design and Implementation of Industrial Gateway for AUTBUS and TSN Protocol Conversion

The integration of AUTBUS and Time-Sensitive Networking (TSN) enables real-time, deterministic control data transmission to underlying devices while supporting long-distance, large-scale data transfer. Despite their potential, limited research has been conducted on the interworking between AUTBUS and TSN, hindering the combined deployment of these advanced network technologies in industrial applications. This paper addresses this gap by focusing on seamless interconnection between AUTBUS and TSN. It explores protocol conversion methodologies, examines a heterogeneous network architecture, and details data link layer and comprehensive network frame format conversion techniques, as well as flow identification mapping. Additionally, the paper presents the design of a protocol conversion gateway, covering both its software and hardware architecture. Experimental results demonstrate that the gateway effectively bridges AUTBUS and TSN, ensuring seamless communication and successful protocol conversion between devices adhering to their respective standards.
