基于SDN与NFV技术的第五代移动通讯方法研究

Research on the fifth generation mobile communication method based on SDN and NFV technology

在5G时代,由于传统的网络传输架构缺乏灵活性,已无法满足用户的各种需求。为了适应5G通讯系统中的不同场景(如eMBB、URLLC等),本文提出了一种基于NFV和SDN的5G业务核心网络管理体系结构,并基于该结构提出了一种最优工作负载分配算法。该框架结合SDN、NFV,可以提供分布式和按需的网络功能部署、网络切片、灵活的网络功能编排和最优的工作负载分配。仿真结果表明,该框架和算法在降低网络运行成本方面是有效的。

In 5G era,the traditional network architecture for lack of flexibility can’t meet the diverse needs of users,in order to adapt to different scenarios of 5G communication system(such as eMBB,URLLC,etc.),this paper proposes a NFV and SDN based 5G core network management system structure,and puts forward a based on the structure of the optimal workload allocation algorithm.The framework,combined with SDN and NFV,can provide distributed and on-demand network function deployment,network slicing, flexible network function choreography and optimal workload distribution. Simulation results show that the framework and algorithm are effective in reducing the cost of network operation.
