The embodiment of the invention provides a method for determining the communication path of a satellite inter-satellite network, a device and an electronic device. The method for determining the communication path of the satellite inter-satellite network adopts the centralized control idea to facilitate the overall control of the satellite inter-satellite network with frequently changing inter-satellite links. The method comprises: obtaining the data request with the highest priority, as the data request to be processed, ensuring that the data request with the highest priority is serviced withpriority, and reducing the situation that the data request with the highest priority can not be serviced because the data request with the lowest priority occupies a large amount of bandwidth; The link whose available bandwidth is not less than the occupied bandwidth is regarded as the available link, which ensures that the data request can occupy enough bandwidth. According to the communicationdelay of the available link, the communication path between the source node and the destination node can be determined, which can reduce the communication delay. The method can realize the communication of satellite inter-satellite network with frequent topology changes and improve the QoS of satellite inter-satellite network with frequent topology changes.
