Modeling of Corporate Network Performance and Smoothing Spline Interpolation

Achieving excellent network quality of service (QoS) is the fundamental aim of any internet service provider (ISP), in view of this, a model of a corporate network has been developed, simulated and implemented using optimized network engineering tool (OPNET) technology in the simulation area of 10,000m 2 office topology to monitor the effect of data delay in a network based on the host users; 50, 100, 150 and 200 to predict the network performance. The result shows that the network with the less number of host users has the better network performance, which implies that; the more the Number of the host users the higher the network error. The RMSE predicted in each LAN for 50, 100, 150 and 200 host users are 0.000423, 0.0006203, 0.0006629 and 0.001408 respectively. The modeling result predicts that input characteristics have influence over network performance as well as capacity utilization.
