Embodiment Construction
[0017] In the emergency / synchronous / asynchronous mixed virtual channel three-level multiplexing physical channel mode adopted by the present invention, by forming a unified data stream, spacecraft engineering data, audio data, video data, and payload data can be simultaneously transmitted , delay playback data and other different information to process large-capacity, high-speed data, by allocating virtual channels for different business data, dynamically manage and schedule virtual channels in a time-division multiplexed manner to ensure reasonable channels Efficient use of.
[0018] The scheduling algorithm based on the virtual channel multiplexing of the satellite network of the present invention is characterized in that: the scheduling algorithm includes the following steps:
[0019] S1 adopts emergency / synchronous / asynchronous mixed three-level multiplexing method, and divides a cycle of virtual channel scheduling into N t time slots, of which: a part is used for the eme...
