摘 要
随着人们对移动互联业务、物联网以及各种通信应用需求的不断增加,移动通信系统的功能及性能有了更多的挑战,新一代移动通信系统有了更高的要求。第五代移动通信系统(5G)正属于开发研究阶段,如今已有一些新的可以用于第五代移动通信系统的架构。软件定义网络(software defined networking,SDN)就是其中之一,它通过集中控制的网络构架把传统的数据转发和逻辑控制两个功能进行分离,使数据层和控制层实现了分离,从而改善了传统网络结构的封闭、转发受限。低利用率等问题,提高了业务效率也满足了人们对业务的不同需求,所以软件定义网络(SDN)已成为5G网络构架的的关键技术。本文对基于软件定义网络(SDN)的5G网络构架进行了阐述,并列举了几个实际应用,然后设计了一种基于软件定义网络(SDN)的负载平衡,最后分析展望了软件定义网络(SDN)网络构架在未来研究的改变。

Research on Software Defined Networking in fifth-generation
Abstract
As people of mobile Internet services, Internet of things and the increasing demand, a variety of communication applications on mobile communication system function and performance had the higher request, also give new generation of mobile communication system challenge. Fifth generation mobile communication system (5G) is be in development stage. At present, we already have some new wireless transmission technology and network technology. Software defined network (software defined networking, SDN) is one of them, it makes the data layer and control layer to achieve the separation by centralized control network architecture of the traditional data forwarding and logic control to separate two functions, thus improving the traditional forward the network structure of closed, limited,low efficiency and such problems, improve business efficiency and satisfy the people to the different needs of the business, so SDN has become the key technology of 5G network architecture. In this paper, based on the 5G network SDN architecture are expounded, and lists several practical application, and design a load balance based on SDN , in the final analysis is prospected SDN network architecture study of change in the future.
Key words:mobile communications;software defined network;system architecture;load balance
