The idea was stolen, by me and at least one other that I've since seen[*], from another context. Van Jacobson and his team over at LBLL proposed something called a RED gateway. As the queue length increases, random packets are dropped in increasing likelyhood. Evidentally, this provides the right kind of feedback to TCP to have it slow down. I was merely wondering if this might be applied well to the problem at hand. The random method is different than the discard the oldest, and may or may not work better.... Tests are underway right now. Warner [*] Since I made my original suggestion, I have seen mail from Robert Morris forwarded to another list suggesting the same thing, but more coherently.
