Time-Adaptive Numerical Simulation for High Speed Networks

Abstract—As the bandwidth of networks is increasing exponentially, the computational cost to simulate such type of networks is also growing in a similar fashion. This paper presents a scalable simulation method, called timeadaptive numerical simulation, which can be used to represent dynamics of high speed networks using fluid-based models. The new method dynamically adjusts the size of a time step for a numerical solver which solves a system of differential equations representing dynamics of protocols and nodes’ behaviors. The simulation results show that the time-adaptive method reduces the computational time while achieving the same accuracy compared to that of a fixed step-size method.
