The development of SPN provides a new way for the application of 5G transmission network,which can realize the transmission of various services with higher quality,faster speed and broader bandwidth.However,in the field of 5G+ Internet of Vehicles,there are still many challenges.Through the design and construction of the SPN test network,this paper deeply studies the slicing function and service carrying capacity of the SPN system.The research finds that,the slicing function control plane can effectively reduce the complexity of service provisioning and maintenance,and the forwarding plane can also play the functions of bandwidth scheduling and isolation of Internet of Vehicles services through corresponding technologies,so as to greatly improve the security and reliability of the network.
