Network Loop Detector with W5500 and ESP32

Project description

Network Loop Detector with W5500 and ESP32 Overview Network loops can cause serious problems in Ethernet infrastructure. When a loop occurs in a Layer 2 network, broadcast frames can circulate repeatedly through switches and cables. This may result in broadcast storms, high network traffic, packet loss, unstable communication, and even complete network failure. The Network Loop Detector with W5500 and ESP32 project provides a compact hardware-based tool for detecting network loop conditions without requiring a laptop or complex diagnostic software. This project uses an ESP32 as the main…
