3.1 FTP - Test

Realization:

Altogether 8 files (for the 10 MBit/s test) or 16 files (for the 100 MBit/s test) of different sizes were transmitted using FTP over IPv4 and IPv6. The test was performed over a 10 MBit/s ethernet LAN connection and over a 100 MBit/s ethernet LAN connection. The source-host for the 10 MBit test was smaug.fh-regensburg.de, running NetBSD 1.6.1. For the 100 MBit test it was yui.fh-regensburg, also running NetBSD 1.6.1.
These computers are hosts on our local network, like as well the destination-host rfhnt8004.fh-regensburg.de. ( Description under point 1)
The ftp-deamon included in NetBSD is implemented with IPv6 support by default.
On rfhnt8004 we installed different operating systems on its scsi-hard discs.

Each of these files was transmitted 10 times and a mean value was computed out of the raised Performance-values.

The fact that the transmissions really used the IPv6 resp. IPv4 Protokoll was checked with the sniffer Ethereal.
Now two screenshots of an v4 and a v6 packet displayed with Ethereal are shown:

Client software:

The client-ftp software used throughout this test was nc-ftp3.1.5. This famous ftp-client exists for nearly every common operating system and can be used by
shell-scripts because of its non-interactive mode (ncftpget resp. ncftpput). Because it is open software its sources and binaries can be obtained from www.ncftp.com
but it does not support IPv6 by default. We compiled v6 supporting binaries using the patch ncftp-315-v6-20030207.diff from the KAME-project. www.kame.net
For our client side scripting under an UNIX environment we used the shell scripts  FTPTestScrIP6.sh  and  FTPTestScrIP4.sh  .

3.1.1 NetBSD 1.6 --> Microsoft Windows XP

There was no need to compile nc-ftp for Windows because a excellent running and v6 supporting version of this programm can be obtaind from http://win6.jp
We automated the transfer using  batchfiles. (  FTPTestScrIP4WIN.bat.htmlFTPTestScrIP6WIN.bat  )

The following meanvalues were computed out of the exact values: ( FTPPerfOUTIP4Win.txt FTPPerfOutIP6Win.txt  )

3.1.2 NetBSD 1.6 --> SuSE Linux 8.2

The transmission was performed by a shell script ( FTPPerfOutIp6Linux.txtFTPPerfOutIP4Linux.txt   ) which uses ncftpget3.1.5.
To compute the mean values a special shell script was used. ( analyze.sh  )

3.1.3 NetBSD 1.6 --> NetBSD 1.6.1

The shell-scripts mentioned above were used to transmit the files from their source host to rfhnt8004. In this case we worked with ncftp303 because this
is the latest availible version of ncftp in the NetBSD  package-sourcetree. The sourcecode of our ncftp client was patched using the
ncftp-303-v6-20010707.diff patch from KAME. Refer to FTPPerfOutIP4NetBSD and FTPPerfOutIP6NetBSD for the exact values.
