摘　　要：传统的数据中心网络难以为指定业务的网络带宽需求提供保障.基于SDN(Software Defined Network)的网络带宽保障系统通过在Floodlight控制器中开发网络带宽保障服务,并采用MVC(Model View Controller)模式设计出一个客户端软件,能够实现用户对网络状态的实时监控和对带宽保障策略的灵活调度.在Mininet搭建的虚拟网络环境中进行测试的结果显示,该系统能够实时监控网络状态、灵活调度带宽保障策略,进而准确有效地保障网络中指定业务的带宽需求.Traditional data center network has difficulty in guaranteeing the network bandwidth requirements of specified services. By developing network bandwidth guarantee services in Floodlight controller and designing client software using MVC（Model View Controller） pattern, the network bandwidth guarantee system based on SDN（Software Defined Network） is designed to enable users to monitor the network status real-timely and schedule the bandwidth guarantee strategies flexibly. Through the tests in the virtual network environment which is created by Mininet, the results show that this system can monitor the network status real-timely, schedule bandwidth guarantee strategies flexibly and then guarantee the bandwidth requirements for specified services in the network accurately and effectively.
