Abstract :

The issue of buffer sizing is rightly receiving increasing attention with the realization that the 
bandwidth delay product rule-of-thumb is becoming unsustainable as link capacity continues to grow. 
In this talk we examine this issue from the light of our understanding of traffic characteristics and the 
performance of statistical bandwidth sharing. We demonstrate through simple analytical models 
coupled with the results of ns2 simulations that, while a buffer equivalent to the bandwidth delay 
product is certainly unnecessary, the recently advocated reduction to a few dozen packets is too 
drastic. The required buffer size depends significantly on the peak exogenous rate of 
multiplexed flows.
