Removed the old lwIP homepage from the example web server filesystem and replaced it with a simple web page with short information about the lwIP project. Previously the web pages in the example web server was a large portion of the final .tar.gz file.

<h4>DHCP client</h4>

<p align="justify">
|

Leon Woestenberg from Axon Digital Design B.V. has written a CS8900a
|
|
||||||
network interface driver and is currently developing a DHCP client for
|
|
||||||
lwIP. They can both be found <a
|
|
||||||
href="http://www.esrac.ele.tue.nl/~leon/lwip/">here</a>. The plan is
|
|
||||||
to eventually integrate Leon's DHCP client in the main lwIP
|
|
||||||
distribution.

<h4>IGMPv2 implementation</h4>
|

<p align="justify">
|

Steve Reynolds of Citel Technologies Ltd. has donated his IGMPv2
|
|
||||||
implementation for lwIP to the community. It is avaliable for download
|
|

<a href="download/igmpfiles.zip">here</a> (note that the copyright and
|
|
||||||
license differs slightly from lwIP - read the license in the igmp.c
|

file). The plan is to integrate his code into the main lwIP
|
|
||||||
distribution.

<h4>Alternative BSD socket layer</h4>

Paul Sheer has incorporated lwIP into his PaulOS system and has
|

written an alternative BSD socket layer. It is avaliable for download

<h1>lwIP - A Lightweight TCP/IP Stack</h1>
|
||||||
|
<p>
|
||||||
|
The web page you are watching was served by a simple web
|
||||||
|
server running on top of the lightweight TCP/IP stack <a
|
||||||
|
href="http://www.sics.se/~adam/lwip/">lwIP</a>.
|
||||||
|
</p>
|
||||||
|
<p>
|
||||||
|
lwIP is an open source implementation of the TCP/IP
|
||||||
|
protocol suite that was originally written by Adam Dunkels
|
||||||
|
of the Swedish Institute of Computer Science but now is
|
||||||
|
being actively developed by a team of developers
|
||||||
|
distributed world-wide. Since it's release, lwIP has
|
||||||
|
spurred a lot of interest and has been ported to several
|
||||||
|
platforms and operating systems. lwIP can be used either
|
||||||
|
with or without an underlying OS.
|
||||||
|
</p>
|
||||||
|
<p>
|
||||||
|
The focus of the lwIP TCP/IP implementation is to reduce
|
||||||
|
the RAM usage while still having a full scale TCP. This
|
||||||
|
makes lwIP suitable for use in embedded systems with tens
|
||||||
|
of kilobytes of free RAM and room for around 40 kilobytes
|

<h2>Using lwIP with or without an operating system</h2>
|
|
||||||
|
|
||||||
<p align="justify">
|
|
||||||
There has been a few questions about how lwIP can be used in a
|
|
||||||
standalone environment (i.e., an environment without a multi-threaded
|
|
||||||
operating system) lately. The purpose of this document is to describe
|
|
||||||
how lwIP is designed to be used with and without a multi-threaded
|
|
||||||
operating system.
|
|
||||||
</p>
|
|
||||||
|
|
||||||
<center><img src="os.png"></center>
|
|
||||||
|
|
||||||
<h3>The lwIP single-threaded core</h3>
|
|
||||||
<p align="justify">
|
|
||||||
The core of lwIP consists of the actual implementations of the IP,
|
|
||||||
ICMP, UDP, and TCP protocols, as well as the support functions such as
|
|
||||||
buffer and memory management. The core components are the only ones
|
|
||||||
that are needed when lwIP is to be run in a single-threaded (non-OS)
|
|
||||||
environment.
|
|
||||||
</p>
|
|
||||||
<p align="justify">
|
|
||||||
The core components can be viewed as a software library which has the
|
|
||||||
following interface:
|
|
||||||
</p>
|
|
||||||
<ul>
|
|
||||||
<li><tt>ip_input(pbuf, netif)</tt>: Takes an IP packet and the incoming network
|
|
||||||
interface as arguments and does the TCP/IP processing for the packet.
|
|
||||||
<li><tt>tcp_tmr()</tt>: Should be called every 100 ms. Does all TCP
|
|
||||||
timer processing such as doing retransmissions.
|
|
||||||
</ul>
|
|
||||||
<p align="justify">
|
|
||||||
Because none of the core functions ever needs to block when run in a
|
|
||||||
single-threaded environment, the <tt>sys_arch</tt> (the operating
|
|
||||||
system abstraction layer) does not need to implement locking
|
|
||||||
semaphores or mailboxes. In future versions of lwIP, the dependancy of
|
|
||||||
the <tt>sys_arch</tt> will be removed in the single-threaded case.
|
|
||||||
</p>
|
|
||||||
<p align="justify">
|
|
||||||
A simple main loop for a single-threaded system might look
|
|
||||||
like this:
|
|
||||||
</p>
|
|
||||||
<pre>
|
|
||||||
while(1) {
|
|
||||||
if(poll_driver(netif) == PACKET_READY) {
|
|
||||||
pbuf = get_packet(netif);
|
|
||||||
ip_input(pbuf, netif);
|
|
||||||
}
|
|
||||||
|
|
||||||
if(clock() - last_time == 100 * CLOCK_MS) {
|
|
||||||
tcp_tmr();
|
|
||||||
last_time = clock();
|
|
||||||
}
|
|
||||||
}
|
|
||||||
</pre>
|
|
||||||
|
|
||||||
<h3>lwIP in a multi-threaded system</h3>
|
|
||||||
<p align="justify">
|
|
||||||
lwIP is designed to be able to be run in a multi-threaded system with
|
|
||||||
applications running in concurrent threads. The model used in this
|
|
||||||
case is that all TCP/IP processing is done in a single thread. The
|
|
||||||
application thread communicate with the TCP/IP thread using the
|
|
||||||
sequential API.
|
|
||||||
</p>
|
|
||||||
|
|
||||||
<center><img src="threads.png"></center>
|
|
||||||
|
|
||||||
<p align="justify">
|
|
||||||
The inter-thread communication is implemented in the two files
|
|
||||||
<tt>api_lib.c</tt> and <tt>api_msg.c</tt>. The former contains the
|
|
||||||
functions used by the application programs and the latter implements
|
|
||||||
the TCP/IP stack interface. A third file, <tt>tcpip.c</tt>, handles
|
|
||||||
incoming packets and timer events as described in the previous
|
|
||||||
section.
|
|
||||||
</p>
|
|
||||||
|
|
||||||
<p align="justify">
|
|
||||||
When run in a multi-threaded environment, incoming packets are handled
|
|
||||||
by the function <tt>tcpip_input()</tt>, which takes the same arguments
|
|
||||||
as the <tt>ip_input()</tt> function. The difference between the two
|
|
||||||
functions is that the <tt>tcpip_input()</tt> function does not process
|
|
||||||
the incoming packet immediately. It merely puts the packet on a queue
|
|
||||||
which later is drained by the TCP/IP thread.
|
|
||||||
</p>
|
|
||||||
|
|
||||||
<p align="justify">
|
|
||||||
When being run in a multi-threaded system, timer events are taken care
|
|
||||||
of internally in <tt>tcpip.c</tt>.
