Dear Juan,

I'm not sure I understand you. Are you just trying to find a
junk-creating program?

If you're on Linux or anything vaguely similar

dd if=/dev/zero bs=1024 count=65536 | netcat some.ip.add.ress port

works well. If netcat doesn't work, try nc, socket, socat, or any of the
other options available. (You can use ping for latency monitoring - it
isn't perfect, but it'll do in a pinch.)

On Windows, any number of programs can be abused for this purpose;
WinZip comes to mind. You can then send it off someplace using whatever
program you please (Outlook and IE (FTP) can be used, if necessary).
