5G移动通信中基于安全信任的网络切片部署策略研究

Network Slicing Deployment Strategy based on Security and Trust in 5G Mobile Communications

传统的基于安全信任的网络切片部署策略对于网络流量的控制能力较差,导致5G移动通信网络中资源利用率较低,影响网络的安全。为此,设计5G移动通信中基于安全信任的网络切片部署策略:设定5G移动通信网络切片结构,为网络信息资源处理提供构架基础;设置资源分配以及分配成本约束条件,控制网络切片资源分配;使用OpenFlow交换机作为流量调度部署设备,设定网络流量调度方式。实验结果表明,此策略使用后网络切片的资源利用率明显高于传统策略使用后的网络资源利用率,使用效果更佳。

The traditional security and trust based network slicing deployment strategy has poor control over network traffic,leading to low resource utilization in the 5G mobile communication network and affecting the network security.To this end,a network slicing deployment strategy based on security and trust in 5G mobile communications is designed:set the 5G mobile communication network slicing structure to provide an architecture basis for network information resource processing;set resource allocation and allocation cost constraints,and control network slicing resource allocation;use OpenFlow switches as traffic scheduling deployment equipment to set the network traffic scheduling methods.Experimental results show that after this strategy is used,utilization rate of network slicing is significantly higher than that after the traditional strategy is used,and the use effect is better.
