This application provides a routing, routing path, and
multicast routing path decision-making method and electronic device. The
routing decision-making method includes acquiring first information of a source node
satellite and second information of a destination node
satellite in a routing path decision-making task; determining a
satellite to be decided upon, and designating neighboring node satellites of the satellite to be decided upon as candidate routing node satellites; acquiring the real-time
traffic load of the candidate routing node satellites and the predicted
traffic load within a preset future
time step; and, based on the real-time
traffic load, the predicted traffic load, the first information, and the second information, determining the next routing node satellite from the candidate routing node satellites using a
routing decision-making model pre-constructed based on a Markov
decision process. The routing, routing path, and
multicast routing path decision-making method and electronic device of this application can determine both real-time performance and accuracy, thereby effectively improving
data transmission efficiency.
