So basically I agree with your problem statement, however I think it would be benficial if your proposed solution was a bit more specific, or at least pointed more in that direction. To propose a solution that sounds more like "limit buffers to 100ms or less and everything will be fine" would indeed remove some of the problem, but it would hurt performance for some applications.
The key to the solution is better Adaptive Queue Management, or AQM. As long as we have to decide on fixed queue sizes for all traffic, we're forced to cater to the most common traffic type. It would be nice to put queues of different RTT into different queues. Today that is basically impossible. -- Leo Bicknell - bicknell@ufp.org - CCIE 3440 PGP keys at http://www.ufp.org/~bicknell/
