摘要
网络地址转换(NAT)是计算机网络实验的重要内容,一般和访问控制列表(ACL)搭配使用,在保证内网安全的前提下,能够实现Internet访问,是组建综合性、复杂性网络的基础。该文利用Packet Tracer仿真软件模拟真实环境,要求学生根据需求,自行设计和实现实验方案,并对实验结果进行验证和分析,有助于学生深入理解网络技术原理,同时增强独立分析和解决问题的能力。实践表明,应用仿真软件开展实验教学,学生学习的主动性有所提高,教学效果良好。
Network address translation(NAT)is an important part of computer network experiments,which is generally used with access control list(ACL),under the premise of ensuring the network security,at the same time to enable Internet access,NAT is the basis of the forming a comprehensive and complex network.This paper uses Packet Tracer simulation software to simulate the real environment,students are required to design and fulfill the project according to the needs.The experimental results are also required to be verified and analyzed.This teaching method can help students to thoroughly understand the principle of network technology,while enhancing the ability of independent analysis and problems solving.Practice shows that the application of simulation software to carr^^out experimental teaching,student learning initiative has improved,the teaching effect is good.
