AI Technical Summary
Existing satellite communication link switching strategies cannot meet the QoS requirements of streaming media services, especially the data transmission packet loss and low network resource utilization caused by frequent link switching in satellite networks.
By acquiring the source and destination nodes in the satellite network, using the shortest path tree and remaining lifetime, the backup route for the target streaming media service is determined. Combining resource consumption thresholds and interruption probability, the optimal backup path is selected to reduce time complexity and network packet loss rate.
It improves the efficiency of satellite communication link switching, reduces network packet loss, meets the QoS requirements of streaming media services, and reduces the impact of large-scale networks.
