摘　　要：虽然当前有多种路由实验手段,但是都不能很好的满足研究人员的需求.而OpenFlow作为一个新兴的技术,它将网络的数据转发功能和逻辑控制功能分离开来,使得网络能够实现充分的可编程性.因此,科研人员开始研究以OpenFlow网络为基础开展网络实验.本文提出了一种基于OpenFlow技术的路由实验方法:用开源的网络模拟软件mininet模拟网络拓扑,用控制器控制流量的转发逻辑以达到实验目的.借助于开源的RouteFlow控制器平台,将路由的逻辑控制转移到通用的虚拟的计算环境中,使得模拟的OpenFlow网络具备路由转发功能.本文也搭建了的原型系统,证明了这种解决方案的可行性,为后期的实验工作提供了参考.Although there have been several ways for networking routing experiments, none of them can meet all the needs of networking researchers. OpenFlow is an emerging network technology. In OpenFlow architecture, the control and data plane are decoupled, which fully enable the programmability of the network. Therefore researchers start to conduct network experiments based on the OpenFlow network. In this paper we propose a method to conduct routing experiment with OpenFlow technology. We simulate the network topology with open source networking simulation software mininet, and control the network flows with an OpenFlow controller. With the open source RouteFlow controller platform, we transfer the routing calculation to general virtual machine, which enable the OpenFlow network with routing feature. We also deploy a prototype and prove the practicability of this solution, which paves the way for future researches.
