lwIP (lightweight IP) is a widely used open source TCP/IP stack designed for embedded systems. lwIP was originally developed by Adam Dunkels at the Swedish Institute of Computer Science and is now developed and maintained by a worldwide network of developers.

lwIP is used by many manufacturers of embedded systems. Examples include Altera (in the Nios II operating system), Analog Devices (for the Blackfin DSP chip),[1] Xilinx,[2] Honeywell (for some of their FAA certified avionics systems) and Freescale Semiconductor (Ethernet Streaming SW for Automotive microcontrollers).

The focus of the lwIP TCP/IP implementation is to reduce resource usage while still having a full-scale TCP.[3] This makes lwIP suitable for use in embedded systems with tens of kilobytes of free RAM and room for around 40 kilobytes of code ROM.
