Abstract

This disclosure provides a satellite network routing method, apparatus, device, storage medium, and program product. It divides the operating cycle of the target satellite network into several time windows based on a preset time granularity. Within each time window, a snapshot is generated based on link information and solar interference information. Preset attributes of the target service are extracted, and it is determined whether the target service passes through a solar interference area in the snapshot. In response to determining that the target service passes through a solar interference area in the snapshot, the links within the solar interference area are removed, generating a routing domain snapshot. The routing domain snapshot is divided into a solar interference area, a transition area, and a normal area. The source node and target node of the target service are determined, and the transmission path of the target service is determined based on the positional relationship between the source node and target node and the solar interference area, transition area, and normal area. This disclosure can dynamically adapt to changes in satellite network topology, significantly improving network service reliability and resource utilization efficiency.
