基于虚拟化技术的软件定义网络实验教学方案

摘要

提出了采取虚拟仿真实验教学手段进行软件定义网络(Software Defined Network,SDN)实验教学,给出了具体的实验教学方案.采用网络仿真平台Mininet 构建SDN网络,采用OpenDayLight控制器集中式控制SDN网络.最后以“SDN转发表控制”实验为例,对提出的SDN实验教学方案进行实验过程展示.在整个实验的实验过程中,学生只需通过简单的操作就可以完成SDN控制器对整个网络设备集中化管控与调度.提出的基于虚拟化技术的SDN实验教学方案有助于提高SDN课程的教学质量和激发学生学习SDN的兴趣.%The paper briefly introduced the concept,characteristic and the development trend of SDN (Software Defined Network),and put forward virtual simulation experiment teaching means to SDN experiment teaching.The SDN experiment teaching scheme was designed as follows:Mininet,a network simulation platform,was adopted in simulating SDN networks,and OpenDayLight controller was adopted in the centralized control Network.Finally,using " SDN forwarding control" experiment as an example,the paper detailed the scheme of SDN experiment teaching by the whole experimental process.Students can use SDN controller to carry out the network of the centralized control and scheduling by the simple operation in the experiment.The proposed SDN experiment teaching scheme based on virtualization technology was helpful to improve the teaching quality of SDN and arouse the students' interest in learning SDN.
