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 tenths of kilobytes of free RAM and room for
|
|
around 40 kilobytes of code ROM.
|
|
|
|
lwIP features:
|
|
* IP (Internet Protocol) including packet forwarding over multiple
|
|
network interfaces
|
|
* ICMP (Internet Control Message Protocol) for network maintenance
|
|
and debugging
|
|
* UDP (User Datagram Protocol) including experimental UDP-lite
|
|
extensions
|
|
* TCP (Transmission Control Protocol) with congestion control, RTT
|
|
estimation and fast recovery/fast retransmit
|
|
* Specialized API for enhanced performance
|
|
* Optional Berkeley socket API
|
|
|
|
lwIP is freely available under a BSD license.
|
|
|
|
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. A core team
|
|
will improve lwIP by the use of Savannah's interface and CVS.
|
|
|
|
The current lwIP CVS tree can be checked out by doing:
|
|
cvs -d:pserver:anoncvs@subversions.gnu.org:/cvsroot/lwip login
|
|
cvs -z3 -d:pserver:anoncvs@subversions.gnu.org:/cvsroot/lwip co lwip
|
|
|
|
Last night's CVS tar ball can be downloaded from:
|
|
http://savannah.gnu.org/cvs.backups/lwip.tar.gz
|
|
|
|
The current CVS tree is web-browsable:
|
|
http://savannah.nongnu.org/cgi-bin/viewcvs/lwip/lwip/
|
|
|
|
Submit patches and bugs via the lwIP project page:
|
|
http://savannah.nongnu.org/projects/lwip/
|
|
|
|
Stable releases have not been released yet. For development we
|
|
suggest downloading the latest CVS and keeping track of the
|
|
lwIP mailing list.
|
|
|
|
The mailing list (with searchable archives), as well as Adam
|
|
Dunkels' papers on lwIP are at the official lwIP home page:
|
|
http://www.sics.se/~adam/lwip/
|
|
|
|
Reading Adam's papers and browsing the mailing list archives
|
|
is a good way to become familiar with the design of lwIP.
