Everyday has done a meticulous piece of confirmation of the practical effect of the STM policy. ShaperProbe reported nothing. That doesn't surprise me having read the learned paper on how ShapeProbe works and the extent of the field studies performed.

The studies were performed in the USA and AFAIK (and I've done searches), none of the ISPs concerned use the same system that is deployed at VM; ALLOT Communications traffic shaper.

The ALLOT system works by de-prioritising user packets whose rate exceeds a threshold (the STM limits). This occurs if the server's buffers are full and the packet is delayed until there higher priority packets have been cleared. I don't think the strategy has changed only the application policy.

I'm not the expert here so others might add better value. But unless ShaperProbe can capture this method, it will return a negative report.
