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.distributed network model; stream reservation; Time-sensitive networking (TSN)Accident prevention; Network architecture; Deterministic communications; Distributed models; Distributed network model; Distributed networks; Distributed time; High bandwidth communication; Network models; Real-time application; Stream reservation; Time-sensitive networking; Time division multiple accessconference paper10.23919/APNOMS52696.2021.95626222-s2.0-85118156160
