Nowadays, the technological avenues in modern techniques of networking have provided means to resolve the challenging environment of traffic engineering. Prima facie, video conferencing that has gained worldwide popularity, has led us to an idea to optimize its’ video traffic by using Multi-protocol Label Switching as opposed to conventional IP Networks. MPLS can be a promising technology in dealing with real time applications that have low network delays and provide efficient utilization of network resources. In our study to model certain scenarios of both IP and MPLS networks, we found Optimized Network Engineering Tool (OPNET) to be the best suited tool in providing comparative performance statistics of throughput and end to end packet delay. The Simulations showed better performance of the MPLS environment over IP Networks when traffic for video conferencing were analyzed and their results were compared.
