Desenvolvimento de uma ferramenta para análise de vazão em redes de computadores

Abstract

This work presents the development of a tool with a graphical interface for automated analysis of throughput in Wi-Fi networks, using the UDP protocol. The proposal arose from the identification of limitations in widely used tools, such as Speedtest and iPerf, which require manual configurations or are not suitable for measuring the performance of local networks. These limitations were highlighted through a practical analysis of iPerf, whose tests showed the absence of automatic mechanisms for adjusting the transmission rate and the lack of a graphical interface as obstacles to usability. The developed solution adopts a client-server architecture and was implemented in Python, using the socket, customtkinter, threading and time libraries, allowing simple and practical tests between two devices connected to the same network. After development, tests were performed that demonstrated the ease of use of the tool and its ability to automatically evaluate the performance of local Wi-Fi networks.
