摘要：
As an emerging technology of industrial communication, time-sensitive networking (TSN) can provide high reliability and deterministic latency guarantee for industrial control traffics. This article proposes a latency upper-bound analysis model based on network calculus for time-aware shaper (TAS) widely used in TSN. The proposed model gives an explicit analysis for upper-bound of the end-to-end latency under multiple TSN-node networking scenarios, which can be used to evaluate the quality of service (QoS)-guarantee performance of the current gate control list (GCL) setting, as well as to help to simplify the complexity of GCL setting. In the model simulation part, the main factors affecting the end-to-end latency are compared and analyzed, and the validity of the latency upper-bound given by the proposed model is verified with OMNeT++. © 2023 Science Press.
