【摘要】：基于嵌入式WEB的反向登录技术的远程网络实训环境与网络的实际建设有一定差异性，就是网络线路的复杂性及协议的多样性。为了能够给师生提供最好的、真实的实验环境，，那就要求网络实验室尽可能的去模拟这些复杂的环境。这就要求在网络实验室的构建中，既能够模拟宽带数据城域网及大型园区网的组网方式和业务思路，又能构建多种类型的局域网和广域网。通过本人多年的教学研究，发现在网络专业的课程之初，实训室里的网络设备本身都具有初始配置，但学生在做完实验后，（如IP、网关等）初始配置的参数都发生了变化，给以后的课程带来不便。为了保证教学质量，因此需要恢复网络设备的初始信息。对于一个大的网络实验室而言，必须能够提供一种简便的方式能够同时管理多台设备。 针对以上问题本研究将远程试验系统引入河北软件职业技术学院网络技术实训室建设的真实项目，首先通过思科cisco25系列路由器实现反向telnet构建终端服务器，利用H3C路由器和交换机等多台真实设备，应用业界内较成熟的嵌入在多端口路由器内的应用程序，以较小的投入，巧妙地呈现出搭建远程网络实训环境的全过程,实现远程试验系统的体系架构；其次给出了某高校的体系结构图,植入嵌入式DMC软件平台系统，并根据网络实验室的基本要求和管理方式对其进行了简单的功能描述和线路分析,详细阐述了实验室的解决方案,总结了系统的特点和优势。在实践过程中，本文作者参考行业著名思科公司具有代表性的带外登录技术，深入挖掘H3C网络设备功能，巧妙的应用了业界较为成熟的H3C嵌入式通用路由平台VRP所特有的系统扩展试验设备管理系统DMC，底层采取反向telnet技术实现了对串行RS232通信端口的驱动，上层实现了与用户的web交互，采用图形界面完成对网络实验拓扑的操控，解决了原实训室应用过程中插拔设备的弊病，既保护了设备，又延长了设备使用寿命。同时，成功搭建了远程网络教学平台，实现了远程网络教学实训的扩展功能。

[Abstract]:There is a certain difference between the remote network training environment based on embedded WEB reverse login technology and the actual construction of the network, that is, the complexity of the network line and the diversity of the protocols. In order to provide the best and real experimental environment for teachers and students, the network laboratory is required to simulate these complex environments as much as possible. This requires that in the construction of network laboratory, it can not only simulate the networking mode and business ideas of broadband data metropolitan area network and large campus network, but also construct various types of local area network and wide area network. Through my many years of teaching and research, it is found that at the beginning of the course of network major, the network equipment in the training room has its own initial configuration, but after the experiment, the parameters of the initial configuration (such as IP, gateway, etc.) have changed, which brings inconvenience to the future courses. In order to ensure the teaching quality, it is necessary to restore the initial information of the network equipment. For a large network laboratory, it must be able to provide an easy way to manage multiple devices at the same time. In order to solve the above problems, this study introduces the remote test system into the real project of the network technology training room of Hebei Software Vocational and Technical College. Firstly, the reverse telnet is realized through the Cisco cisco25 series router to construct the terminal server, and several real devices, such as H3C routers and switches, are used to apply the more mature application programs embedded in the multi-port router in the industry with less investment. The whole process of building remote network training environment is skillfully presented, and the architecture of remote test system is realized. Secondly, the architecture diagram of a university is given, and the embedded DMC software platform system is implanted. according to the basic requirements and management mode of the network laboratory, the simple function description and circuit analysis are carried out, the solution of the laboratory is expounded in detail, and the characteristics and advantages of the system are summarized. In the process of practice, referring to the representative out-of-band login technology of famous Cisco company in the industry, the author deeply excavates the functions of H3C network equipment, and skillfully applies the system extension test equipment management system DMC, which is unique to the industry H3C embedded general routing platform VRP, to realize the driver of serial RS232 communication port by adopting reverse telnet technology in the bottom layer, and realizes the web interaction with users in the upper layer. The graphical interface is used to complete the control of the network experiment topology, which solves the disadvantages of inserting and pulling the equipment in the application process of the original training room, which not only protects the equipment, but also prolongs the service life of the equipment. At the same time, the remote network teaching platform is successfully built, and the expansion function of distance network teaching training is realized.
