摘　　要：以深入理解软件定义网络(SDN)技术基本原理和解决当前网络存在的问题为出发点,结合线上线下实验资源,设计了虚拟型和实体型两大类实验项目,每类实验均有基本型和创新型。虚拟实验基本型有基于浏览器的线上和基于本地虚拟机的线下实验,创新型实验以掌握SDN应用开发基本流程为目标。实体实验基本型包括三种类型实体SDN交换机实验,创新型实验以解决网络实际问题为目标。实验结果显示,分类实验较好地满足了不同学生的实践需求。Aiming at deep understanding the basic principles of software defined network(SDN)technology and solving problems in the current networks,combining with online and offline experimental resources,two classes experimental projects were designed,virtual and physical,each class has two types of experiments of basic and innovative.The basic type of virtual experiments include browser-based online and local virtual machines based offline experiments,and the innovative experiments aim is to master the basic process of SDN application.The basic physical experiments include three types of physical SDN switch experiments,and the innovative experiments aim to solve the problems in real networks.The experimental results show that the classification experiment satisfies the practical requirements of different students.
