Abstract :
This letter investigates buffer behavior in data center networks (DCNs). An analytical framework to model a switch buffer in a DCN is proposed. Based on a martingale perspective, we derive the expectation of the stopping time, and we provide explicit expression for the relationship between overflow probability of the stopping time and buffer size. Simulations are given to validate the analysis. In addition, an example is provided to explain how the method can be applied to switch design.
