[Plug alert]

For longer term monitoring, Project BISmark provides an easy-to-use
system. It's an open source, customizable OpenWRT-based home router that
runs periodic network measurements (latency, throughput, packetloss,
jitter, etc) to nearby MLab servers.

It uses netperf (single and multiple TCP threads), and shaperprobe,
(UDP) for throughput measurements.

Although its original target audience is home users, it can also be used
as a monitoring tool in bigger networks.

It'd be nice to know if NDT was not accurate as well.  Anyone tested it?

We've been using it for a few years. On my laptop that runs linux I get
fairly consistent results (around 935Mb/s up and down right now) over a
1Gig routed link (a couple routers and a firewall in between.) On the
Windows boxes I usually see a 100 to 200 Mb/s drop on the upload side.
The last time I checked, you can compile a commandline version of the
client. I seem to remember the commandline client not taking quite as
bad a hit on the tests compared to running it on linux, but it's been a
while since I tried it.

For us it's been way more accurate than the various speedtest servers
our customers insist on trying. A while back I switched from compiling
my own kernel and NDT to using perfSONAR-PS
(http://psps.perfsonar.net/). I like that they've got live-cd and
net-install versions. If nothing else it's useful for pointing out the
difference between a local network issue and Internet Suckage.
