ConnMan
ConnMan (Connection Manager) is a lightweight, open-source daemon designed to manage network connections on Linux-based embedded systems and IoT devices. It provides a modular framework for handling wired, wireless, cellular, and VPN connections, with a focus on low resource usage and fast connection setup. It integrates with system services like D-Bus for communication and supports various backends for different network technologies.
Developers should learn ConnMan when building or maintaining embedded Linux systems, IoT devices, or mobile platforms where efficient network management is critical, such as in automotive infotainment, smart appliances, or routers. It is particularly useful in scenarios requiring minimal memory footprint, rapid network switching, and support for multiple connection types without heavy dependencies like NetworkManager.
