【摘要】 鉴于计算机网络硬件实验平台的局限性,应用虚拟仿真软件进行实验教学是必要的。简要介绍了Packet Tracer网络仿真软件并阐述了通用路由封装协议(Generic Routing Encapsulation,GRE)隧道技术原理,进而基于Packet Tracer仿真软件设计了GRE隧道配置实验方案,包括实验目的、网络拓扑结构设计、网络参数设置、实验环境配置,以及上述配置结果的验证方式等。教学实践表明:采用该实验方案进行教学有助于学生对网络知识的理解掌握和综合运用,可以作为传统网络实验教学的有效补充和扩展。更多还原

【Abstract】 Due to the limitation of hardware experimental platforms for computer network, it is necessary to apply virtual simulation software in experimental teaching. The Packet Tracer network simulation software and the theory of GRE tunnel technology are briefly introduced. An experimental scheme for GRE tunnel configuration based on Packet Tracer in presented, including purpose of the experiments, design of the network topology, configuration of network parameters and experimental environments, and validation of the configuration aforementioned. Teaching practices indicate that this experimental scheme is helpful for the students to understand and use the knowledge of network and that the proposed scheme is a valid expansion of the classical network experiments.更多还原
