This invention belongs to the field of communication and
network control technology. To address the problems of poor adaptability in non-ideal observation environments and the inability of a single optimization objective to meet various
differentiated service requirements, and to overcome scheduling failures caused by network
jitter or node failures leading to
data loss, this invention provides: a time-sensitive network traffic scheduling method based on causal data completion. This method collects real-time traffic data from the
current time-sensitive network (TSN) and constructs an irregular
observation matrix; it uses a state reconstruction module based on neural
Granger causality to complete the
missing data in the
observation matrix; it extracts robust spatiotemporal features with
noise resistance from the completed
observation matrix using a variational graph
attention network; and it inputs these robust spatiotemporal features into a
reinforcement learning decision network based on hierarchical optimization. Under the hard real-time constraint of priority
critical time-triggered TT flow, it optimizes the best-effort BE flow transmission efficiency, ultimately generating a gated control
list for execution. This invention is primarily applied in design and manufacturing applications.
