Maybe you could have a look at that page
:http://kb.pert.geant2.net/PERTKB/BandwidthMeasurementTools
that extensively use IPPERF/BWCTL so as to troubleshoot TCP window
issue. Basically, PERT (Performance Enhancement Response Team) is
mainly focused on Performance issue.
Hope this help,
Cheers/Fred

Actually, you can use IP SLA for bandwidth testing too. You just need to
find some file which can be pulled off the internet via HTTP/FTP, and
use IP SLA to get it.
The only thing is that you would be killing your user's access to the
net at the time of the test, so testing during peak hours would be out
of the question, while testing the bandwidth in off-peak hours does not
mean much, as the ISP would have extra BW...
I would monitor the response time for HTTP for small web sites, and just
monitor the trend. The bottom line is that your end users do not really
care about the raw amount of bandwidth, but are really looking for good
response time and consistent service level.
Its called "Quality of Experience" as opposed to "Quality of Service".

You can use netperf to test bandwidth, cron it to run daily for 10
seconds and it will report the bandwidth on your circuits.

IP SLA seems to be the best option at present. Although we monitor with
some open source tools. I would like to have a way to check that I am
getting what (bandwidth) I am paying for if this makes sense.
It seems to me that these programs only monitor the circuits not test
throughput. I want to be able to test throughput on the circuit. These
third party sites are ok but I am sure there is someway providers are
doing this with out using speedtest sites?

Dear rootnet,
Not a direct solution to what you want, but did you consider using IP
SLA for constant performance monitoring?
You can setup a few IP SLA HTTP probes to well known sites and monitor
the performance trend. This would give you a real indication of the
"quality of experience".

Hi List,
Is there some sort of tool you can load into the IOS on a router to
check bandwidth? Or if not what are you all doing these days in this
situation.
Like for example things are running slow and you think the Internet
feed
may be the problem is there a way to do speed tests on the router
itself?
