With the rapid development of Low Earth Orbit(LEO)mega-constellation networks,satellite communica-tion systems have become massive in scale with highly dynamic topologies,making intelligent networking a research focal point.This article surveys intelligent networking technologies for LEO mega-constellations,analyzes their net-working characteristics and challenges,proposes an overall architecture for intelligent networking,and systematically reviews five key directions:service awareness and demand prediction,dynamic topology and mobility management,beam scheduling strategies,inter-satellite routing strategies,and intelligent management of multidimensional re-sources.First,we review methods for service awareness and demand prediction,covering traditional single-satellite approaches,AI-based single-satellite approaches,and multi-satellite collaborative prediction.Second,we discuss dy-namic topology and mobility management,tracing the evolution from traditional static management to dynamic schemes oriented to multidimensional resources.Third,for beam scheduling strategies,we describe beam-scheduling methods for single satellites as well as multi-satellite cooperative beam scheduling.Fourth,we examine inter-satellite routing strategies in depth,surveying both centralized and distributed approaches.Finally,we discuss in-telligent management of multidimensional resources from the perspectives of static and dynamic resource manage-ment.On this basis,we analyze the remaining challenges in intelligent networking for LEO mega-constellations,criti-cally assess the effectiveness and limitations of current techniques,and outline future research directions.
