							- INTRODUCTION
 
- lwIP is a small independent implementation of the TCP/IP protocol
 
- suite that has been developed by Adam Dunkels at the Computer and
 
- Networks Architectures (CNA) lab at the Swedish Institute of Computer
 
- Science (SICS).
 
- The focus of the lwIP TCP/IP implementation is to reduce the RAM usage
 
- while still having a full scale TCP. This making lwIP suitable for use
 
- in embedded systems with tens of kilobytes of free RAM and room for
 
- around 40 kilobytes of code ROM.
 
- FEATURES
 
-   * IP (Internet Protocol) including packet forwarding over multiple network
 
-     interfaces
 
-   * ICMP (Internet Control Message Protocol) for network maintenance and debugging
 
-   * IGMP (Internet Group Management Protocol) for multicast traffic management
 
-   * UDP (User Datagram Protocol) including experimental UDP-lite extensions
 
-   * TCP (Transmission Control Protocol) with congestion control, RTT estimation
 
-     and fast recovery/fast retransmit
 
-   * Specialized raw/native API for enhanced performance
 
-   * Optional Berkeley-like socket API
 
-   * DNS (Domain names resolver)
 
-   * SNMP (Simple Network Management Protocol)
 
-   * DHCP (Dynamic Host Configuration Protocol)
 
-   * AUTOIP (for IPv4, conform with RFC 3927)
 
-   * PPP (Point-to-Point Protocol)
 
-   * ARP (Address Resolution Protocol) for Ethernet
 
- LICENSE
 
- lwIP is freely available under a BSD license.
 
- DEVELOPMENT
 
- lwIP has grown into an excellent TCP/IP stack for embedded devices,
 
- and developers using the stack often submit bug fixes, improvements,
 
- and additions to the stack to further increase its usefulness.
 
- Development of lwIP is hosted on Savannah, a central point for
 
- software development, maintenance and distribution. Everyone can
 
- help improve lwIP by use of Savannah's interface, CVS and the
 
- mailing list. A core team of developers will commit changes to the
 
- CVS source tree.
 
- The lwIP TCP/IP stack is maintained in the 'lwip' CVS module and
 
- contributions (such as platform ports) are in the 'contrib' module.
 
- See doc/savannah.txt for details on CVS server access for users and
 
- developers.
 
- Last night's CVS tar ball can be downloaded from:
 
-   http://savannah.gnu.org/cvs.backups/lwip.tar.gz [CHANGED - NEEDS FIXING]
 
- The current CVS trees are web-browsable:
 
-   http://savannah.nongnu.org/cgi-bin/viewcvs/lwip/lwip/
 
-   http://savannah.nongnu.org/cgi-bin/viewcvs/lwip/contrib/
 
- Submit patches and bugs via the lwIP project page:
 
-   http://savannah.nongnu.org/projects/lwip/
 
- DOCUMENTATION
 
- The original out-dated homepage of lwIP and Adam Dunkels' papers on
 
- lwIP are at the official lwIP home page:
 
-   http://www.sics.se/~adam/lwip/
 
- Self documentation of the source code is regularly extracted from the
 
- current CVS sources and is available from this web page:
 
-   http://www.nongnu.org/lwip/
 
- There is now a constantly growin wiki about lwIP at
 
-   http://lwip.wikia.com/wiki/LwIP_Wiki
 
- Also, there are mailing lists you can subscribe at
 
-   http://savannah.nongnu.org/mail/?group=lwip
 
- plus searchable archives:
 
-   http://lists.nongnu.org/archive/html/lwip-users/
 
-   http://lists.nongnu.org/archive/html/lwip-devel/
 
- Reading Adam's papers, the files in docs/, browsing the source code
 
- documentation and browsing the mailing list archives is a good way to
 
- become familiar with the design of lwIP.
