Against the backdrop of digital education, the campus network has become an indispensable infrastructure in universities, yet the limitations of traditional operation models have become increasingly prominent. This paper systematically presents the entire process of the free campus network reform initiated by Dalian Jiaotong University, focusing on its background, implementation paths, existing challenges, and optimization strategies. It explores the construction of an on-demand service system for campus networks, and practical experience can provide some reference and guidance for sister universities.
