What tools are you guys using to qualify network bandwidth /throughput?

I'm not talking standard ISP “Speedtest” apps, but dedicated hardware or software solutions.

There are companies out there that produce software tools for intensive network troubleshooting but all seem to be based at enterprise networking and are therefore at enterprise price levels!!

I am looking at something more suited to small and high end residential networks.

we have various Fluke hardware for infrastructure and connectivity testing but nothing that load tests the network or can analyse existing traffic and bandwidth.

TIA, Nick
