3.2. HTTP-Test

We did perform the HTTP-Test in order to be able to compare the performance characteristics of the ip-stacks with values raised by a
test on the same application layer level as FTP. In fact HTTP is a protocol on top of tcp which is in top of ip. So the values can be compared
with the ones raised by the FTP test which is also a protocol on top of tcp.

Realization:

We transmitted the same files like we did in the FTP-test, but in this case we only considered transmission over 100 MB/s ethernet LAN. The realization was the same like in the FTP-test: Each file was transmitted 10 times and a mean value was computed out of these values. The source host was yui.fh-regensburg.de and the destination host was rfhnt8004.fh-regensburg.de.
We compiled apache 1.3.28 out of its patched source code using the KAME-patch apache-1.3.28-v6-20030912.diff.gz in order to make it IPv6 enabled
and then installed it on yui. Because we wanted apache to run on a non privilleged port (8000) we had to include "listen 0.0.0.0 8000" in the httpd.conf file.
On the client side we used wget 1.7 in its IPv6-ready patched version using wget-17-v6-20010716a.diff.gz from KAME.
Wget was used because we didn`t want to use only one client programm throughout the whole test. If we had done so, we would possibly not recognize a performance effect which reasons are in the implementation of the client.

3.2.1 NetBSD 1.6 --> WinXP

A precompiled binary version of wget 1.7 for Windows XP with built in IPv6 support is availible at http://win6.jp and was used for this test. The guys at http://win6.jp have compiled several applications for the Microsoft plattform using Cygwin and the patches from KAME. Also in the case of wget it was done in this way, so we can assume to use nearly the same sources as we do in the UNIX-environment.

3.2.2 NetBSD 1.6 --> SuSE Linux 8.2

In order to get wget 1.7 compiled with IPv6 support using the above mentioned KAME-patch, we had to modify the Makefile of wget in the following way:
The DEFS statement of the makefile had to be extended by the definition "-DINET6". This is necessary to tell the compiler to use the #define INET6 preprocessor command.
