Note that the paper "Characterizing Residential Broadband Networks" by Dischinger, et. al. indicates that a large fraction (in their 2 year old sample, 30% or so) of broadband head ends are running without RED, and should be doing so if at all possible; alternatives are years out by the time they are tested and deployed, and operators running without it in congested systems are inflicting pain on their customers.
Something I've observed is if you are sending data 'upstream' on the cable modem setup i have (16 down/ 2 up) and you saturate the upstream, the buffering destroys any downstream capability at the same time. I'm not even sure where to start diagnosing to explaining this to the carrier involved, as this isn't the desired behavior of a "business class" service. - Jared
