Improving Triple Play Services Using Multi Protocol Label Switching Technology

Abstract

<b>Problem statement:</b> Traditional IP networks have many limitations such as routing tables, which can be complex and time consuming. These limitations affect the performance of the network in some applications of triple play services (i.e., voice, video and data) which are characterized as time sensitive applications. Thus, Multi Protocol Label Switching (MPLS) technology has been proposed to speed up the traffic flow in the network using labels. <b>Approach:</b> In this study, an experiment using the Network Simulator NS-2 was performed to evaluate the impact of MPLS technology on the Triple Play Services based on the average throughput of the network, total number of packets received at destination nodes and packet loss rates and this is compared to that provided by traditional IP networks. <b>Results:</b> The results showed that MPLS performs better since it utilizes all the available paths to the destinations. <b>Conclusion:</b> MPLS allows Internet Services Providers (ISPs) to provide better triple play services for end-users

Hybrid Traffic Management Model for Multi-Protocol Label Switching Network

“…The author presented a two-phase heuristic approach to solve this formulation efficiently. Yasin and Ibrahim (2010) explains the MPLS hierarchical architecture for label-switched networks can be used to address all required functions of converged/unified networks, from initial IP level authentication and configuration, security, session control, resource reservation, admission control, to quality of service and policy management, enhanced only where necessary to address the idiosyncrasies of the mobile wireless environment. This architecture encompassing mostly Internet Engineering Task Force (IETF) standardized protocols, takes advantage of MPLS flexibility to address wireless-specific requirements such as micro mobility as well as nonwireless specific requirements, such as traffic engineering and quality of service and does not involve specific requirements in the mobile terminal for initiating label-switched paths over the wireless interface and allowing end to end interconnection to the backbone network.…”
