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/. +
