Abstract
The change of industrial automation towards a highly interconnected architecture is still ongoing. Time-sensitive networking (TSN) is an essential element for this transition. This paper focuses on TSN end stations, mainly answering how to implement a software-based worst-case execution time (WCET) analyzable buffer management. The two-level segregated fit (TLSF) algorithm was chosen, implemented, and evaluated based on an asymptotic complexity analysis of dynamic storage allocation algorithms. The implemented and improved TLSF algorithm showed similar timing behavior as calculated when executed on a time-predictable platform. The paper concludes by outlining further research.
