Design And Implementation Of Network Management System For Future Classroom

With the rapid development of Internet and various emerging of technologies, the construction of the future classroom is an important area of the education industry, and has gradually attracted wide attention and discussion at home and abroad.At present, the application of various intelligent hardware and software facilities in the field of education is becoming more and more extensive. This paper discusses the design and implementation of network access management system in the future classroom, aiming at creating a convenient 、safe and reliable network access management system. It adopts the scheme of SSH security protocol, API HTTP as the control interface, JSON data as the data structure, which not only ensures the security of the system, but also takes into account the ease of use and scalability.This paper analyzes the development of education in China in the information age, and discusses the dilemma of the traditional multimedia classroom. Secondly, based on the exploration and conception of the future classroom, the concept and features of the classroom and the network environment in the future classroom are analyzed. Finally, the main research work and chapter arrangement of this paper are introduced.Secondly, several common network protocols are analyzed, and their security is compared. The architecture, workflow and security of SSH protocol are emphasized. Through the comparison of security, the secure channels of SSH protocol are determined to accomplish the communication of data.Then, the system needs analysis and detailed design, and the system development structure and function modules are completed. And the key technology of the system is analyzed, including TCP connection, Libssh2 function library, JSON data format. Subsequently, in Chapter 4, the concrete realization of the function modules of the system, including the login function, view state switches, management of the cable network, wireless network management, display CPU and memory utilization rate information and view the log file. And in the fifth chapter, the operating status of the system is tested, and the security of data transmission is studied.At last, a summary of the paper is made, and the shortcomings of the system and the need to improve are presented, and then the future research is prospected.This paper detailed describes the design and implementation of access network system in the classroom of the future, especially remote login management based on the SSH protocol. It has certain guiding significance to improve the security of the network in the future classroom and remote centralized management of terminal equipments.
