We've launched Project BISMark, a project that performs active performance measurements of upload and download throughput, latency, etc. from OpenWRT-based routers running inside of homes. We have tested our OpenWRT image on the NetGear WNDR 3700v2 and are currently shipping out NetGear routers with the BISMark firmware to anyone who is interested.
Please, pretty please, with sugar on top, don't just do active measurement, but also do passive measurement of real traffic. Doing test traffic is one case, but the really important thing to look at is real traffic. I tried to get traction for this on IETF75, but there seems to be little interest.
On a NAT router there is a state table, what would the performance penality be to look at TCP sequence numbers, RTTs (TCP timestamps) to be able to discern PDV and loss of the actual traffic the customer is doing?
There are a lot of test suites, they solve one problem, but a passive monitoring system that would show how the real traffic is behaving would yield a lot more valuable information that just relying on active testing (which will cause harm to customer traffic when the test is run).
