摘　　要：在车联网环境下,针对道路拥堵过程中RSU拥塞导致的链路拥塞,通信质量下降,用户服务质量降低等问题,基于SDN架构,采用网络切片方法实现RSU负载均衡功能。利用SUMO和Mininet-WiFi联合仿真,采用Django框架构建监测系统,实时监测调度过程。结果显示:在不同阶段,RSU负载均衡系统均可充分利用带宽,能满足更多应用请求并保障较高优先级应用请求。In the context of the Internet of Vehicles,aiming at the problems such as link congestion,communication quality decline and user service quality decrease caused by RSU congestion during road congestion,based on SDN architecture,network slicing method was adopted to realize RSU load balancing function.In addition,through joint simulation of SUMO and Mininet-WiFi,a monitoring system was constructed by using Django framework to monitor the scheduling process in real time.Experimental results show that,at different stages,RSU load balancing system can fully utilize the bandwidth to meet more application requests and ensure application requests with higher priority.
