The article mainly analyzes the structure of distributed computer network and the specific measures for its optimization. The distributed computer network includes the connections and servers of different clients, and the architectural style is introduced into the existing "computer communication network excellent course system", which makes the system more concise and standardized, and improves the scalability of the system. At the same time, any system can communicate with other systems. Compared with other network structures, the multi-version parallel development mode is adopted to ensure the development of new functions and the improvement of stability. This enables new requirements functions to be quickly responded to in high versions, while reducing their impact on the stability of the framework itself.
