La mejor manera de demostrar esto es con una prueba de iPerf. WebActually, QoS requires two TBF to be applied to a data stream. One of them controls steady state burst size, another one with rate P (peak rate) and depth M (equal to link MTU) limits bursts at a smaller time scale. It is easy to see that P>R, and B>M. If P is infinity, this double TBF is equivalent to a single one.
