elessair | 0:f269e3021894 | 1 | INTRODUCTION |
elessair | 0:f269e3021894 | 2 | |
elessair | 0:f269e3021894 | 3 | lwIP is a small independent implementation of the TCP/IP protocol |
elessair | 0:f269e3021894 | 4 | suite that has been developed by Adam Dunkels at the Computer and |
elessair | 0:f269e3021894 | 5 | Networks Architectures (CNA) lab at the Swedish Institute of Computer |
elessair | 0:f269e3021894 | 6 | Science (SICS). |
elessair | 0:f269e3021894 | 7 | |
elessair | 0:f269e3021894 | 8 | The focus of the lwIP TCP/IP implementation is to reduce the RAM usage |
elessair | 0:f269e3021894 | 9 | while still having a full scale TCP. This making lwIP suitable for use |
elessair | 0:f269e3021894 | 10 | in embedded systems with tens of kilobytes of free RAM and room for |
elessair | 0:f269e3021894 | 11 | around 40 kilobytes of code ROM. |

elessair | 0:f269e3021894 | 45 | DEVELOPMENT |
elessair | 0:f269e3021894 | 46 | |
elessair | 0:f269e3021894 | 47 | lwIP has grown into an excellent TCP/IP stack for embedded devices, |
elessair | 0:f269e3021894 | 48 | and developers using the stack often submit bug fixes, improvements, |
elessair | 0:f269e3021894 | 49 | and additions to the stack to further increase its usefulness. |
elessair | 0:f269e3021894 | 50 | |
elessair | 0:f269e3021894 | 51 | Development of lwIP is hosted on Savannah, a central point for |
elessair | 0:f269e3021894 | 52 | software development, maintenance and distribution. Everyone can |
elessair | 0:f269e3021894 | 53 | help improve lwIP by use of Savannah's interface, Git and the |
elessair | 0:f269e3021894 | 54 | mailing list. A core team of developers will commit changes to the |
elessair | 0:f269e3021894 | 55 | Git source tree. |
elessair | 0:f269e3021894 | 56 | |
elessair | 0:f269e3021894 | 57 | The lwIP TCP/IP stack is maintained in the 'lwip' Git module and |
elessair | 0:f269e3021894 | 58 | contributions (such as platform ports) are in the 'contrib' Git module. |
elessair | 0:f269e3021894 | 59 | |
elessair | 0:f269e3021894 | 60 | See doc/savannah.txt for details on Git server access for users and |
