Hi,

end-to-end bandwith meters are available on the net, like: http://www.2wire.com/

Between you and your provider this is however useless.
Only real test you can do, is to ftp between your local machine, and the your home-page of your provider. At the end of the transfer it calculates and reports the transfer-rate
take care to use several sizes (64KB...1MB).
If the transfer is too short (< 10 seconds) it might report fals values.

Also check traffic BOTH ways.
You can automate this by putting this all in a .netrc file...... (starting it from a script, generate a plot file with gnuplot, putting it on the web...)

I gkrellm to keep a real time eye on the bandwidth being used. Testing the bandwidth on the first leg can difficult. In my case there is a gateway box at the other end with no services (not even ping!). gkrellm will graphically show the last 30 seconds or so of usage on all your network interfaces.

I've found that downloading a hefty USGS DLG map is a good long distance ftp test. We got up to 300K byte/second while testing with a microwave/T1.
