If you are gonna run a presentation to show-off aDSL, remember the 'a' for

ADSL is tuned towards downloading rather than uploading...it was originally
intended as a media-streaming solution...
The upstream is typically 1/8 of the downstream, so bidirectional

Sorry for the slow reply to you Kevin, and the group.
I've been away for most of last week.

Well I work for a Telecoms training centre. We have just installed a
number of ADSL access nodes for training purposes which are accessing a
Linux web server through an ATM switch and an IP router. I have been
involved in the installation of the system and I want to demonstrate the
speed and reliability of ADSL during the training courses.
I guess that video streaming and videophone stuff would be really good
demonstrations, but I also want to show a measurement of the available
So what is the best way to measure the available bandwidth + latency?
Are there any good applications out there for this?

The ADSL "modems" we are using will work with Linux, or any other
system that can drive an Ethernet card. It's configured via a web
has the ability to do NAT (when in routing mode)
I guess that I could organise some demos to ILUG members if there is
