TSN can operate in centralized and distributed models, and the distributed model is more suitable for the safety-critical applications that require high network availability and reliability. However, the existing approach for the TSN's fully distributed model makes a pessimistic latency bound estimation due to the problems of lower priority streams and dependency. The pessimistic estimation will result in a decrease in the schedulability of TSN streams. This paper identifies and evaluates the impact of the two problems via a case study and then proposes a TDMA-based stream reservation approach to alleviate the two problems. The simulation results validate the proposed approach in terms of the number of accepted streams and computation time. © 2021 IEICE. |
