I don't know if you are referring to the "RED in a different light" paper: that was never published, though an early draft escaped and can be found on the net.
"RED in a different light" identifies two bugs in the RED algorithm, and proposes a better algorithm that only depends on the link output bandwidth. That draft still has a bug.
I also noticed another paper published later that references "RED in a different light": http://www.icir.org/floyd/adaptivered/ Adaptive RED: An Algorithm for Increasing the Robustness of RED's Active Queue Management (postscript, PDF). Sally Floyd, Ramakrishna Gummadi, and Scott Shenker. August 1, 2001. And this one: http://citeseerx.ist.psu.edu/viewdoc/download?doi=10.1.1.98.1556&rep=rep 1&type=pdf July 15, 2002 Active Queue Management using Adaptive RED Rahul Verma, Aravind Iyer and Abhay Karandikar Abhay But it doesn't look like aRED went anywhere
