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

  13 FEATURES
  14
  15   * IP (Internet Protocol) including packet forwarding over multiple network
  16     interfaces
  17   * ICMP (Internet Control Message Protocol) for network maintenance and debugging
  18   * IGMP (Internet Group Management Protocol) for multicast traffic management
  19   * UDP (User Datagram Protocol) including experimental UDP-lite extensions
  20   * TCP (Transmission Control Protocol) with congestion control, RTT estimation
  21     and fast recovery/fast retransmit
  22   * Specialized raw/native API for enhanced performance
  23   * Optional Berkeley-like socket API
  24   * DNS (Domain names resolver)
  25   * SNMP (Simple Network Management Protocol)
  26   * DHCP (Dynamic Host Configuration Protocol)
  27   * AUTOIP (for IPv4, conform with RFC 3927)
  28   * PPP (Point-to-Point Protocol)
  29   * ARP (Address Resolution Protocol) for Ethernet

  35 DEVELOPMENT
  36
  37 lwIP has grown into an excellent TCP/IP stack for embedded devices,
  38 and developers using the stack often submit bug fixes, improvements,
  39 and additions to the stack to further increase its usefulness.
  40
  41 Development of lwIP is hosted on Savannah, a central point for
  42 software development, maintenance and distribution. Everyone can
  43 help improve lwIP by use of Savannah's interface, CVS and the
  44 mailing list. A core team of developers will commit changes to the
  45 CVS source tree.
  46
  47 The lwIP TCP/IP stack is maintained in the 'lwip' CVS module and
  48 contributions (such as platform ports) are in the 'contrib' module.
  49
  50 See doc/savannah.txt for details on CVS server access for users and
  51 developers.

  53 Last night's CVS tar ball can be downloaded from:
  54   http://savannah.gnu.org/cvs.backups/lwip.tar.gz [CHANGED - NEEDS FIXING]
  55
  56 The current CVS trees are web-browsable:

  58   http://savannah.nongnu.org/cgi-bin/viewcvs/lwip/contrib/

  64 DOCUMENTATION
  65
  66 The original out-dated homepage of lwIP and Adam Dunkels' papers on
  67 lwIP are at the official lwIP home page:
  68   http://www.sics.se/~adam/lwip/
  69
  70 Self documentation of the source code is regularly extracted from the
  71 current CVS sources and is available from this web page:
  72   http://www.nongnu.org/lwip/
  73
  74 There is now a constantly growin wiki about lwIP at
  75   http://lwip.wikia.com/wiki/LwIP_Wiki
  76
  77 Also, there are mailing lists you can subscribe at
  78   http://savannah.nongnu.org/mail/?group=lwip
  79 plus searchable archives:
  80   http://lists.nongnu.org/archive/html/lwip-users/
  81   http://lists.nongnu.org/archive/html/lwip-devel/
  82
  83 Reading Adam's papers, the files in docs/, browsing the source code
  84 documentation and browsing the mailing list archives is a good way to
  85 become familiar with the design of lwIP.
