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.

-Shahid.

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,
Naeem

I don't have hard data, but my soft data is that generally, devices branded as switches (including L3 switches) do not support it. Routers might.
