Fiction-reading websites usually store users 'web novels offline so that users can read them on different devices. This kind of offline storage technology was generally called "distributed storage". It used multiple storage servers to store the novel data to improve the storage efficiency and stability. In the novel reading network system, every user had an account and a reading progress. After the user logged in, the system would store the user's reading progress and the data of the novels they had read. At the same time, the novel reading network would also use some technical means, such as the use of CDA (Content Delivery Network), to distribute the data to different servers to improve the effect and range of the buffer. When the user wanted to read the same novel, the system would first retrieve the latest version of the data from the server and then upload the data to the server for updating. Therefore, even if the user logs in to the system on different devices, the latest data can be automatically obtained from the buffer server to ensure the user's reading experience.
