How do you understand the problems ? Before designing the networks
Network design analysis is the most critical and the hardest part of Computer network design.Designers should be trained to understand the real problems

You are right. We call those short ovarloads , microburst. Microbursts also will be hold in the buffer but the problem is , in the high speed links those buffers get full within couple milliseconds. 

What I am saying in my article, you can protect some traffic thats right but if you have enough load , eventually one flow will die couple milliseconds after another and all those end to end qos design is not worth to manage that complexity, especially if you have large scale network.
