"局域网聊天软件设计与实现:Linux下TCP通信与数据库应用"
The bachelor's degree thesis "The Design and Implementation of the LAN Chat Software" is a comprehensive study on developing a LAN chat application for Linux systems using C language. The software is designed to provide functions such as automatic user list refreshing, message communication through TCP protocol, and user authentication through a MySQL database. This design aims to create a simple and secure LAN chat software for internal use within enterprises and laboratories, without data exchange with the internet, with advantages in speed and security. The thesis focuses on the following key aspects: data parsing for user log-in/out notifications and message communication, TCP network programming to create clients and servers, and implementation and analysis of the software's design and functioning process. Key words related to the study include: Linux, TCP, Socket, MySQL database, and C. The research and development of the LAN chat software took place in Beijing University of Posts and Telecommunications, representing a practical application of theoretical knowledge in computer science and networking. The software's implementation and analysis provide an in-depth understanding of the underlying processes involved in creating a network application and the challenges faced in ensuring its functionality and safety. Overall, the thesis provides valuable insights into the design and implementation of a LAN chat software, shedding light on the technical intricacies and considerations involved in similar projects.
