Performance Comparison of Real-Time Video Conferencing In MPLS and IP Networking Environment

Abstract

Modern techniques in networking have evolved a diverse range of opportunities to resolve the challenging task of traffic engineering. With a principle focus on video conferencing that has gained popularity worldwide, we contrive to optimize video traffic by using Multiprotocol Label Switching (MPLS) rather than conventional Internet Protocol (IP) networks. MPLS can be a promising technology for real-time applications with low network delays and efficient utilization of network resources. To substantiate this, in this paper we model certain scenarios of both IP and MPLS networks using Optimized Networking Engineering Tool (OPNET) to simulate and provide comparative performance statistics of throughput and end-to-end packet delay. We illustrate that MPLS has the ability that makes it stand out to IP by analyzing the simulation results of both networking mechanisms.
