Naeem,
If you look into the document I initially sent
http://research.microsoft.com/en-us/um/people/ssaroiu/publications/imc/2007/imc2007-dischinger.pdf
They show that 26% of DSL lines have RED actually deployed - and tuned on!
They did not detect any RED on the cable side.

Mikael,
The shallow marking theshold is not the most significant feature of
the AQM in DCTCP. More importantly, it does not delay congestion
signals by averaging them over a period equivalent to a worst-case
RTT (about 100ms), like all other AQMs do (RED, PIE, CoDel etc).

Thanks Shahid
Although interesting to know that (W)RED has made it into some hardware (in
your RE to Lars' point), my question is more about "deployment" at the edge
or the core, whether it's being used or not?
Cheers,
