【摘要】 为了增强软件定义网络课程实验的灵活性和可扩展性,使用Mininet模拟器作为基础架构,并结合P4语言,搭建了基于真实操作系统内核的轻量级虚拟化实验环境。以通过编写P4程序来实现集中控制交换机数据转发的实验为例,介绍了P4语言的主要组成部分以及用法,展示了实验环境中网络拓扑的配置、路由的配置、P4程序的编写和用户交互流程。更多还原

【Abstract】 In order to enhance the flexibility and scalability of the Software Defined Network course experiment, the Mininet-based infrastructure and P4 language are used to build a lightweight virtualized experimental environment based on the real operating system kernel. Taking the experiment of writing P4 program to centrally control the data forwarding of the switch as an example, the experiment introduces the main components and usage of P4 language and shows the network topology configuration, routing configuration, the way of writing P4 program and user interaction process.更多还原
