With the continuous development of information and communication technology, the requirements for expanding network coverage and reducing communication delay are becoming higher and higher.Low earth orbit (LEO) satellite networking, as a network system constructed by satellites with low orbital altitudes, has the advantages of wide coverage and small communication delay.Firstly, the development status of LEO satellite network around and the challenges faced by LEO satellite networking were summarized.Then, the key technical difficulties and suggestions of LEO satellite networking were described.Finally, some potentially feasible LEO satellite networking schemes were discussed, combined with the theory and methods of distribution, game and artificial intelligence.

Key words: LEO satellite networking technology, artificial intelligence, game theory, 6G space Internet
