Fluid Simulation for High Speed Networks 1

We propose to use uid model based time-driven simulation to simulate high speed networks. For single class uid in feedforward networks, we prove that the error introduced by discretizing a uid model is within a deterministic bound proportional to the discretization interval length and is not related to the network size. We show that uid simulation ooers the exibility to trade accuracy for eeciency, and it is also easy to parallelize. These features enable us to speed up simulation by orders of magnitude compared to the event-driven simulation.
