emNet

In the world of embedded systems, IP based communication lays the groundwork for any modern device. High-layer IoT (Internet of Things) protocols such as MQTT (Message Queuing Telemetry Transport) still rely on the availability of a TCP/IP stack to provide lower layers of communication in standard protocols such as TCP. As an industry-leading IP stack specifically designed for embedded devices, emNet is an ideal choice to provide this component. It is straightforward to configure and integrate and can easily be fine-tuned to the varying requirements and constraints of embedded systems.

emNet combines maximum performance with minimal memory requirements and simple integration without configuration effort. Its design, which specifically targets embedded devices, makes it highly efficient in terms of flash, RAM and packet processing speed. This means that even small, low-frequency microcontrollers deliver excellent network performance.

emNet is designed to use a single task for management and handling of incoming packets. SEGGER's IP stack comes with the built-in performance-optimizing feature UDP flood protection which frees up CPU time that can be used for other tasks. It can help to save execution time on incoming data that would be discarded anyhow. Other tasks in the system exist along with emNet and might also use higher priorities than the IP_Task (used for management and processing received packets) to make sure they fulfill their real-time requirements.
