Abstract |
To reduce the computation requirement of large-scale network simulation, this paper presents a direct computing method for discrete event network simulation. In this method, many of the discrete events are replaced by direct computing, so the computation overhead for network simulation is decreased, yet the accuracy of simulation result is kept unchanged. Experiments show, compared with the traditional discrete event network simulator, the direct computing method can decrease the number of discrete events generated during the network simulation by over 50%, and can decrease the simulation running time by over 40%, without the loss of simulation accuracy; the memory required during simulation is also decreased. |
