There has been substantial interest from researchers in the development and contribution of modules in NS2. One of the challenges in NS2 modeling is to seamlessly integrate real world traffic data into the NS2 network model. Normally the traffic in NS2 is generated from the traffic agents such as TCP and UDP agents whose parameters are based on certain statistical distribution. The aim of this paper is to demonstrate how traffic agents in NS2 simulator are used to generate different types of traffic based on real traffic network. In this work, a modified sniffer program was used to capture real traffic data from a production network and output to a traffic text file. This traffic test file is then used by the NS2 traffic agents in the simulated network model representing the real production network. To validate that the simulation works accurately, the output trace file of NS2 after simulation is compared with the traffic generated at the destinations of the production network. Error percentage and t-test data analyses were conducted. It was found, based on comparisons that the difference was nearly zero for traffic captured for duration of around 15 minutes simultaneously generated from four different production sites.
