A Mechanism of Predicting Network Simulation Performance Based on BP Nets

Performance analysis is a key issue in parallel network simulation. This paper proposes a new mechanism of parallel network simulation performance prediction. Analyzing the key factors of impacting parallel simulation performance, six parameters which may determine the time-cost of network simulation is presented. Then we adopt the Back Propagation (BP) network to approximate to the non-linear relation between time-cost and these parameters. So we can carry out a very good prediction to the new network simulation missions with BP nets. This mechanism also does not require configuring all the workstation with same kind of hardware/software environment.
