Analysis of 5G+ Internet of Vehicles Application Based on SPN

SPN is an innovative technology system proposed for 5G transmission. SPN can realize comprehensive service transmission with large bandwidth, low delay and high efficiency in Internet of Vehicles, but there are still problems to be resolved. In this paper, the slicing function and service carrying capacity of SPN system are analyzed by constructing SPN test network. The test data show that the management and control planes of the slice function can greatly reduce the complexity of service opening and maintenance, and the forwarding plane can realize the function of isolation and flexible bandwidth scheduling of the IoV service based on FlexE technology, and the combination of service bearing and Service Router can effectively reduce the risk of service interruption and improve the network security performance.
