| demayer | 0:6bf0743ece18 | 1 | INTRODUCTION |
| demayer | 0:6bf0743ece18 | 2 | |
| demayer | 0:6bf0743ece18 | 3 | lwIP is a small independent implementation of the TCP/IP protocol |
| demayer | 0:6bf0743ece18 | 4 | suite that has been developed by Adam Dunkels at the Computer and |
| demayer | 0:6bf0743ece18 | 5 | Networks Architectures (CNA) lab at the Swedish Institute of Computer |
| demayer | 0:6bf0743ece18 | 6 | Science (SICS). |
| demayer | 0:6bf0743ece18 | 7 | |
| demayer | 0:6bf0743ece18 | 8 | The focus of the lwIP TCP/IP implementation is to reduce the RAM usage |
| demayer | 0:6bf0743ece18 | 9 | while still having a full scale TCP. This making lwIP suitable for use |
| demayer | 0:6bf0743ece18 | 10 | in embedded systems with tens of kilobytes of free RAM and room for |
| demayer | 0:6bf0743ece18 | 11 | around 40 kilobytes of code ROM. |

| demayer | 0:6bf0743ece18 | 14 | FEATURES |
| demayer | 0:6bf0743ece18 | 15 | |
| demayer | 0:6bf0743ece18 | 16 | * IP (Internet Protocol, IPv4 and IPv6) including packet forwarding over |
| demayer | 0:6bf0743ece18 | 17 | multiple network interfaces |
| demayer | 0:6bf0743ece18 | 18 | * ICMP (Internet Control Message Protocol) for network maintenance and debugging |
| demayer | 0:6bf0743ece18 | 19 | * IGMP (Internet Group Management Protocol) for multicast traffic management |
| demayer | 0:6bf0743ece18 | 20 | * MLD (Multicast listener discovery for IPv6). Aims to be compliant with |
| demayer | 0:6bf0743ece18 | 21 | RFC 2710. No support for MLDv2 |
| demayer | 0:6bf0743ece18 | 22 | * ND (Neighbor discovery and stateless address autoconfiguration for IPv6). |

| demayer | 0:6bf0743ece18 | 25 | * UDP (User Datagram Protocol) including experimental UDP-lite extensions |
| demayer | 0:6bf0743ece18 | 26 | * TCP (Transmission Control Protocol) with congestion control, RTT estimation |
| demayer | 0:6bf0743ece18 | 27 | and fast recovery/fast retransmit |
| demayer | 0:6bf0743ece18 | 28 | * raw/native API for enhanced performance |
| demayer | 0:6bf0743ece18 | 29 | * Optional Berkeley-like socket API |

| demayer | 0:6bf0743ece18 | 48 | DEVELOPMENT |
| demayer | 0:6bf0743ece18 | 49 | |
| demayer | 0:6bf0743ece18 | 50 | lwIP has grown into an excellent TCP/IP stack for embedded devices, |
| demayer | 0:6bf0743ece18 | 51 | and developers using the stack often submit bug fixes, improvements, |
| demayer | 0:6bf0743ece18 | 52 | and additions to the stack to further increase its usefulness. |
| demayer | 0:6bf0743ece18 | 53 | |
| demayer | 0:6bf0743ece18 | 54 | Development of lwIP is hosted on Savannah, a central point for |
| demayer | 0:6bf0743ece18 | 55 | software development, maintenance and distribution. Everyone can |
| demayer | 0:6bf0743ece18 | 56 | help improve lwIP by use of Savannah's interface, Git and the |
| demayer | 0:6bf0743ece18 | 57 | mailing list. A core team of developers will commit changes to the |
| demayer | 0:6bf0743ece18 | 58 | Git source tree. |
| demayer | 0:6bf0743ece18 | 59 | |
| demayer | 0:6bf0743ece18 | 60 | The lwIP TCP/IP stack is maintained in the 'lwip' Git module and |
| demayer | 0:6bf0743ece18 | 61 | contributions (such as platform ports) are in the 'contrib' Git module. |
| demayer | 0:6bf0743ece18 | 62 | |
| demayer | 0:6bf0743ece18 | 63 | See doc/savannah.txt for details on Git server access for users and |
| demayer | 0:6bf0743ece18 | 64 | developers. |
| demayer | 0:6bf0743ece18 | 65 | |

| demayer | 0:6bf0743ece18 | 77 | DOCUMENTATION |
| demayer | 0:6bf0743ece18 | 78 | |
| demayer | 0:6bf0743ece18 | 79 | Self documentation of the source code is regularly extracted from the current |
| demayer | 0:6bf0743ece18 | 80 | Git sources and is available from this web page: |
| demayer | 0:6bf0743ece18 | 81 | http://www.nongnu.org/lwip/ |
| demayer | 0:6bf0743ece18 | 82 | |
| demayer | 0:6bf0743ece18 | 83 | There is now a constantly growing wiki about lwIP at |
| demayer | 0:6bf0743ece18 | 84 | http://lwip.wikia.com/wiki/LwIP_Wiki |
| demayer | 0:6bf0743ece18 | 85 | |
| demayer | 0:6bf0743ece18 | 86 | Also, there are mailing lists you can subscribe at |
| demayer | 0:6bf0743ece18 | 87 | http://savannah.nongnu.org/mail/?group=lwip |
| demayer | 0:6bf0743ece18 | 88 | plus searchable archives: |

| demayer | 0:6bf0743ece18 | 92 | lwIP was originally written by Adam Dunkels: |

| demayer | 0:6bf0743ece18 | 94 | |
| demayer | 0:6bf0743ece18 | 95 | Reading Adam's papers, the files in docs/, browsing the source code |
| demayer | 0:6bf0743ece18 | 96 | documentation and browsing the mailing list archives is a good way to |
| demayer | 0:6bf0743ece18 | 97 | become familiar with the design of lwIP. |
