一、引言“计算机网络”是网络工程专业本科生的一门专业基础课,是学生进一步学习后续专业课及从事实际专业工作的基础。而实践教学是该课程教学过程中的重要环节,它可以弥补理论教学的不足,加深学生对理论知识的理解,培养学生在学习中发现问题、分析问题、解决问题的能力。传统“计算机网络”教学主要是以原理部分为中心,教学内容缺乏直观性,而实验教学通 I. INTRODUCTION “Computer Network ” is a specialized basic course for undergraduates majoring in network engineering, which is the basis for students to further study the follow-up specialized courses and engage in practical work. The practice teaching is an important part of the teaching process of the course. It can make up for the deficiency of the theory teaching, deepen the students ’understanding of the theoretical knowledge, cultivate the students’ abilities of finding problems, analyzing problems and solving problems in their study. Traditional “computer network ” teaching is mainly the principle part of the center, the lack of intuitive teaching content, and experimental teaching through
