VLAN划分与NAT地址转换教学实验设计

Design of instructional experiment of VLAN division and Network Address Translation

网络课程是计算机专业的基础课,重视学生掌握理论基础以及培养学生的基础实验技能和研究能力。网络课程实验通过实验教学内容的改进,使学生利用实验室现有实验设备和条件,设置实验项目,设计解决方案,通过实验前后数据对比,达到理论联系实际解决具体问题的教学目的,并在此过程中培养学生独立思考与解决问题的能力。通过将只有一个公网IP的实验室或机房(约70台计算机)进行NAT地址转换和VLAN划分,成功访问互联网并提高访问速率。

Internet is a basic course of computer science,which put emphasis on the mastery of fundamental theories and the cultivation of rudimentary experimental techniques and the ability to conduct researches.With the improvement of the teaching contents in computer network experiments,students are able to utilize the current equipment and conditions to integrate the theory with the practice.Several steps can be followed to achieve the teaching goal:formulating a project,carefully designing a solution and comparing the results obtained from the experiment with the data before it.Meanwhile,the ability of thinking independently and addressing problems is significantly improved.By the means of Network Address Translation and VLAN division in the laboratory(around 70 computers)with only one public IP address,students can succeed in accessing to the Internet at a faster speed.
