Other Open Source TCP/IP Stacks

http://dunkels.com/adam/uip/ uIP - A free small TCP/IP implementation for 8- and 16-bit microcontrollers by Adam Dunkels.

http://ucsu.colorado.edu/~chenf/ 8051WEB is an embedded web server running on top of the uIP TCP/IP stack developed by Adam Dunkels. 8051WEB is ported from uIP by Fajun Chen.

http://digilander.iol.it/ffumi/ This is the first implementaion of a TCP/IP stack on the Casio Pocket Viewer, realized by porting to the PV platform and OS the uIP.

http://www.informatik.fh-hamburg.de/~christ_o/ Cool! TCP/IP for Lego Mindstorm.

http://www.sics.se/~adam/lwip/ 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 tenths of kilobytes of free RAM and room for around 40 kilobytes of code ROM.

uC/IP (pronounced mew-kip) is a project to develop free TCP/IP/PPP stack for uC/OS. The code is based on BSD code and carries the BSD licence. By Guy Lancaster.

eAVR is a group project for the development of GPL'd ethernet communication libraries for Atmel AVR microcontrollers. By Jason Kyle.

Liquorice aims to provide a reliable, high performance, environment for embedded application development. It's a complete new design by Dave Hudson. Unfortunately this interesting project has come to a halt, but the latest release, dated 10/18/2000, is still available for download.
