Research on the Deterministic Ethernet Application for Manned Lunar Exploration
Deterministic Ethernet(Time-Triggered Ethernet and Time-Sensitive Networking)is a technology that adds time synchronization and time-aware shaping to traditional Ethernet to provide deterministic communication services with high reliability and low latency.The application of deterministic Ethernet in spacecraft can solve the problem that the existing bus is difficult to meet the requirements of future space applications such as system architecture openness,real-time data processing and data transmission reliability.This paper analyzes the background,technical principle and development status of deterministic Ethernet technology,and proposes a"first fusion and then enhancement"promotion step,that is,the integrated architecture of Time-Triggered Ethernet and Time-Sensitive Networking is gradually transitioned to a complete Time-Sensitive Networking architecture,which provides ideas for the design and implementation of China's future spacecraft information system data bus.
