基于SDN的5G智慧校园融合专网研究

Research on 5G Smart Campus Converged Private Network Based on SDN

自5G商用以来,中国已经建成了世界最大的5G网络,加快推动智慧校园与5G网络的融合是智慧校园网络建设的方向。通过UPF下沉,实现智慧校园与5G的打通,以5G网络的低时延、高带宽、广链接网络特性及5G网络切片技术特性,解决智慧校园网络重复建设、网络覆盖率低等问题。并基于软件定义网络(Software Defined Network,SDN)的标准化、可编程技术,实现网络的极简管理、细粒度的资源划分,同时提高网络安全等级。基于SDN的智能化、利用5G的网络特性,构建泛在互联的校园5G专网,为校园安防、智慧课室、虚拟数字校园等智慧校园建设提供网络基础,提升教育质量、变革教书育人模式。

Since the commercialization of 5G,China has built the world’s largest 5G network all over the world.Accelerating the integration of smart campus and 5G network is the direction of smart campus network construction.Through UPF sinking,the smart campus and 5G can be connected,and the problems of redundant construction and low network coverage of smart campus network can be solved with the characteristics of low delay,high bandwidth and wide link network of 5G network and the technical characteristics of 5G network slicing.Based on the standardization and programmable technology of Software Defined Network(SDN),it realizes minimal network management,fine-grained resource division and improves network security level.Based on the intelligence of SDN and the network characteristics of 5G,a ubiquitous interconnected campus 5G private network is constructed,which provides a network foundation for the construction of smart campuses such as campus security,smart classrooms and virtual digital campuses,improves the quality of education,and changes the mode of teaching and educating people.
