As the demand for digital office and living environments grows, building and optimizing small local area networks has become an important topic. This article outlines the process of setting up a small LAN, covering hardware selection, network topology design, and network configuration. It introduces network performance testing metrics and methods, using specialized tools to test throughput, latency, packet loss rate, and other metrics on the completed LAN. The test data is analyzed to evaluate network performance, identify performance bottlenecks, and propose optimization strategies. By presenting a complete setup and testing process, this article provides a reference for the construction and performance improvement of small LANs.
