	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.
	12
	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.
	52
	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:
	57	http://savannah.nongnu.org/cgi-bin/viewcvs/lwip/lwip/
	58	http://savannah.nongnu.org/cgi-bin/viewcvs/lwip/contrib/
	59
	60	Submit patches and bugs via the lwIP project page:
	61	http://savannah.nongnu.org/projects/lwip/

	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.scribblewiki.com/
	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.
