为加深学生对计算机网络知识的理解，提高工程实践能力和创新能力，在新工科教育理念指导下，提出“虚实训”三结合实验教学模式，包括真实实验与虚拟实验相结合、真实设备与开源软件相结合、实验教学与项目实训相结合，具体操作包括模块化教学内容、规范教学流程、定义考核标准等，结合校园网设计案例，介绍教学实施流程，阐述教学效果保障措施，实践证明该实验教学方法有助于提高学生创新能力。

In order to deepen students' understanding of computer network knowledge, improve their engineering practice and innovation abilities, under the guidance of the new engineering education concept, a "virtual real training" three combination experimental teaching mode is proposed. Real experiments are combined with virtual experiments, real equipment is combined with open source software, and experimental teaching is combined with project training. The specific operations include modular teaching content, standardized teaching processes, defined assessment standards, etc. Combining with campus network design cases, the teaching implementation process is introduced, and teaching effectiveness guarantee measures are elaborated. Practice has proved that this experimental teaching method helps to improve students' innovation abilities.
