lwIP - A Lightweight TCP/IP Stack

-

- The web page you are watching was served by a simple web - server running on top of the lightweight TCP/IP stack lwIP. -

-

- lwIP is an open source implementation of the TCP/IP - protocol suite that was originally written by Adam Dunkels - of the Swedish Institute of Computer Science but now is - being actively developed by a team of developers - distributed world-wide. Since it's release, lwIP has - spurred a lot of interest and has been ported to several - platforms and operating systems. lwIP can be used either - with or without an underlying OS. -

-

- The focus of the lwIP TCP/IP implementation is to reduce - the RAM usage while still having a full scale TCP. 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. -

-

- More information about lwIP can be found at the lwIP - homepage at http://www.sics.se/~adam/lwip/. -
